3 Lesson 5: Multimedia on the Web 5-3 Introduction to Multimedia on the Web Multimedia on the Web has expanded rapidly as broadband connections have allowed users to connect at faster speeds. Almost all Web sites, including corporate sites, feature multimedia content and interactive objects. For instance, employee orientation sessions, audio and video memos, and training materials are often placed on the Internet or corporate intranets. Nearly all network-connected devices, such as PCs, tablets, smartphones and smart TVs, can view online interactive multimedia. Each device includes a sound card, speakers and a video card. In some cases, small applications called plug-ins are required for browsers to view content that is not supported. Browser plug-ins are commonly used to play streaming audio and video, and interact with multimedia objects. As an IT professional, you should understand the elements required for browsers to view these items. This lesson will introduce you to multimedia content and several popular plug-ins that allow browsers to display it. It will teach you to install and operate some of the most widely used plug-ins. You will also learn how to download and store various types of files from the Internet. CIW Online Resources Movie Clips Visit CIW Online at to watch a movie clip about this topic. Lesson 5: Multimedia on the Web Objects, Active Content and Languages object An element on a Web page that contains data and procedures for how that item will react when activated. On a Web page, an object is typically a multimedia presentation. object-oriented programming (OOP) Programming concept based on objects and data and how they relate to one another, instead of logic and actions; C++ and Java are OOP languages. Objects enable Web authors to include multimedia effects, also called active content, on their sites. These objects can play sounds, show video clips and animation sequences, or demonstrate ideas in 3-D simulations. In addition to making the user's Web experience more enjoyable, these multimedia capabilities can greatly enhance a site's educational value. Many businesses expect to profit from this active approach to Web site design and construction. The following sections discuss various types of programming and scripting languages used to create objects and active content, and their relationships to one another. C C is a programming language used primarily to create operating systems and applications. For instance, many UNIX operating systems have been developed using C. Because object-oriented programming (OOP) is becoming popular, C is being replaced by C++ and Java. In object-oriented programming, a program is handled as a collection of individual objects that perform separate functions, rather than as a sequence of statements that performs a specific task. C++ C++ is a superset of the C language that uses object-oriented programming. Although the names are similar, C++ uses a completely different set of programming concepts than C uses and is considered the best language for creating large applications.

4 5-4 Internet Business Associate Java An object-oriented programming language developed by Sun Microsystems that is fully cross-platform functional. applets Small programs written in Java, which are downloaded as needed and executed within a Web page or browser. Java Java is an object-oriented language developed by Sun Microsystems. Java concentrates on distributed objects over a network (for example, the Internet), and is often used when data needs to be shared across the network. Java can be used on the server side, or on the client side. An end user will never see Java used on the server side. However, they will benefit from this code. When Java is used on the client side, the end user will see a Java applet. Java applets Java applets are programs written in the Java language and designed to run within a Web browser when accessed. Applets were the first technology developed for bringing program objects to the Web. Similar to ActiveX objects (discussed later in this lesson), applets animate pages, add functionality and interactivity, access multimedia services, and provide active content. Java applets are miniature Java programs downloaded into a Web browser when a user requests a Web page. They are treated the same way as other Web-embedded objects and are displayed in the browser's content area. Your Web browser must be Java-enabled to run applets. Most browsers, including Google Chrome, Mozilla Firefox and Windows Internet Explorer, support Java applets. Unlike static objects, such as non-animated GIF and JPEG images or hyperlinks, Java applets can be dynamic and interactive. Their special effects include the following: dynamic Always changing. interactive The characteristic of some hardware and software, such as computers, games and multimedia systems, that allows them to respond differently based on a user's actions. Inline video, changing text, and animation dynamic objects that can be embedded in Web pages without the need for external helper applications or plug-ins. Audio sound files played either when an applet is invoked or in response to user action. User interaction action and responses between a user and the displayed applet. Examples of interactive applets include user-interface controls that allow the user to interact with an on-screen element, such as in a computer game. Real-time data feeds transmissions that maintain an open connection between the server and an applet on a Web page, or periodically poll the server to update information displayed in the browser. Examples of real-time data feeds are online clocks and up-to-the-minute stock market tickers. Applets can combine these properties to create complex but easy-to-use Internet applications. event-driven Reacting to particular user actions or the browser's completion of a specific task. JavaScript The Web is event-driven. For example, when you click or select an element on a Web page, you have caused an event. Events include a mouse click, a mouse drag, text entered or a page loaded (or unloaded) in the browser. JavaScript is an event-driven scripting language because it is designed to react whenever an event occurs. Traditional programming languages, such as C, cause events to happen, rather than reacting to events. By contrast, scripting languages are used within existing programs to extend those programs' capabilities. If you have ever written a macro in Microsoft Word or Excel to perform a task, you have already used a scripting language.

5 Lesson 5: Multimedia on the Web 5-5 JavaScript was the first scripting language developed exclusively for online content design. JavaScript syntax resembles that of traditional programming languages. These scripts are placed within your Web document. When your browser retrieves a page that incorporates JavaScript, it runs the scripts and performs the appropriate operations. JavaScript vs. Java Although the names are similar, JavaScript and Java are completely different languages and share no real similar features. Java is an object-oriented programming language, whereas JavaScript (as the name suggests) is an object-based scripting language. Java, developed by Sun Microsystems, can create stand-alone applications and Java applets. LiveScript The Netscapedeveloped scripting language that was the predecessor to JavaScript. JavaScript, originally developed by Netscape Communications, has its origins in a scripting language called LiveScript. Unlike Java, JavaScript is not a stand-alone programming language: It must reside within HTML documents to run. JavaScript adds interactivity to Web pages without the need for specialized server-based programs. JavaScript complements Java by supporting most of Java's expression syntax and basic program flow controls. It also exposes useful properties of Java applets to JavaScript programmers. JScript JScript is the Microsoft version of JavaScript. Microsoft chose the name JScript due to trademark issues with Netscape, the developer of JavaScript. They are essentially the same language. Though based on the same code, JavaScript and JScript each have additional features not supported by the other. JScript is built into Windows Internet Explorer; JavaScript is built into Mozilla Firefox. Because of the slight differences between JavaScript and JScript, programs written in JavaScript may not function properly within Internet Explorer, and programs written in JScript may not function properly within Mozilla Firefox. C# C# (pronounced "C sharp") is Microsoft's object-oriented programming language; it is Microsoft's answer to Java. Microsoft's.NET platform is designed to explicitly support C#, making the language very popular. You can learn more about C# at the following sites: Microsoft MSDN ( Microsoft MSDN C# blog page ( ActiveX An open set of technologies for integrating components on the Internet and within Microsoft applications. ActiveX ActiveX was first developed by Microsoft, but was then turned over to an independent organization, The Open Group. ActiveX is a strategic initiative that incorporates objectoriented programming tools and technologies. ActiveX is Microsoft's response to Java applets. ActiveX technology enables authors to place interactive objects on their Web sites based on a common standard, and allows the objects to work together. With ActiveX, Web pages can include animation, audio, and video. Web content can be dynamic, providing current information on any topic, customized to the user's profile and preferences.

6 5-6 Internet Business Associate ActiveX is used to create ActiveX controls, which are self-contained programs that can be run anywhere on a network, including within a browser from the Internet. ActiveX controls are similar to Java applets, but officially only run in Internet Explorer and on the Windows operating system. Visual Basic Script (VBScript) Scripting language from Microsoft derived from Visual Basic; used to manipulate ActiveX scripts. Visual Basic The Microsoft graphical user interface (GUI) programming language used for developing Windows applications. A modified version of the BASIC programming language. Visual Basic Script (VBScript) Visual Basic Script (VBScript) is an object-based scripting language that Microsoft derived from its more powerful Visual Basic programming language. VBScript can manipulate two types of objects. The first type is called a standard HTML object, which is an intrinsic object such as those found on a form: a display button, radio button, check box or password field. The second type of object, the ActiveX control, is more powerful and flexible. The ActiveX functions of an object are invoked by user action. Microsoft VBScript is a vendor-specific scripting language. Unlike JavaScript, VBScript may not be supported by browsers other than Windows Internet Explorer.

Exercise 5-1: Programming languages used to create objects and active content Objects and Security Issues To work with downloadable active content such as Java applets and ActiveX objects, you need to understand the security issues involved and know how to protect yourself from hostile incursions. Both ActiveX and Java applets allow information to be downloaded and run on your system. However, some content can cause problems ranging from inconvenience to loss of data. Later in this course, you will learn how both Internet Explorer and Firefox provide control options to enable or disable the execution of Java programs and other active content. You will also learn how to disable active content entirely. This knowledge will allow you to choose the appropriate security setting for your personal computer or your company, and shield your system from dangerous content. HTML5 vs. Plug-ins Before discussing browser plug-ins in detail, you must be aware of Hypertext Markup Language version 5 (HTML5). HTML5 is the latest version of HTML and is gaining acceptance in the Web community. One of the major goals of HTML5 is to eliminate the use of browser plug-ins.

7 Lesson 5: Multimedia on the Web 5-7 Figure 5-1: HTML5 logo HTML5 is a standard provided by the W3C. The practical benefit of this standard is that it gives designers, developers and browser creators a universal framework for embedding videos and other interactive content without first having to install a plug-in. The HTML5 standard benefits end users because you do not have to worry about installing the latest plug-in. The browser's rendering engine and programming handle the video content. One drawback of HTML5, however, is that you must update your browser so that it supports HTML5. Most current browsers support HTML5. However, a large percentage of multimedia content on the Internet is created for browser plug-ins. Adobe Flash is probably the most well-known plug-in for viewing multimedia content, such as videos and interactive content. In an effort to reduce the number of plug-ins, HTML5 offers many options for developers. The following list includes several benefits: Introduces the <video> element, which is designed to eliminate the need to install third-party plug-ins (such as those for Adobe Flash or Apple QuickTime). geolocation An HTML5 application programming interface that allows developers to retrieve the geographical location information for a client-side device. cascading style sheets (CSS) Style sheet language that provides the formatting and "look" of a Web page or document written in a markup language. Adds the <audio> element, which allows pages to seamlessly add audio files for events such as podcasts. No audio plug-in, such as Windows Media Center, is required to listen to music. Establishes ways to enable drag-and-drop capability for Web pages without using third-party add-ons. Many other interactive features that use JavaScript provide the same functionality as plug-ins. Allows geolocation, which is the ability for developers to retrieve the geographical location information for a client-side device. One example is using a mobile device's Global Positioning System (GPS) to determine the device's location, which allows Web services to be provided based on the client's location. To view the HTML5 specifications, go to: HTML5 can produce dynamic multimedia content with JavaScript and Cascading Style Sheets (CSS). These technologies used together provide Web pages that easily adapt to smartphones, tablets, gaming devices and smart TVs, as well as to traditional PCs.

8 5-8 Internet Business Associate Apple co-founder Steve Jobs provided a great argument for using these technologies in his famous "Thoughts on Flash" blog. (Adobe Flash is a browser plug-in that provides multimedia such as video, animation, interactive games and audio.) " we strongly believe that all standards pertaining to the web should be open. Rather than use Flash, Apple has adopted HTML5, CSS and JavaScript all open standards. Apple's mobile devices all ship with high performance, low power implementations of these open standards. HTML5, the new web standard that has been adopted by Apple, Google and many others, lets web developers create advanced graphics, typography, animations and transitions without relying on third party browser plug-ins (like Flash). HTML5 is completely open and controlled by a standards committee, of which Apple is a member." Plug-ins drain system resources. As a result, plug-ins use additional CPU and battery power. This consideration is especially important for users on mobile devices, which depend upon battery power. Battery life can decrease as much as 40 percent on a mobile device when running a plug-in. HTML5 solves this issue by providing native support for animation, movies and other multimedia without the use of plug-ins. CSS and JavaScript are used instead. Despite the plug-in backlash, they will be around for the foreseeable future, perhaps indefinitely. The Android operating system uses plug-ins such as Flash, as do Windows systems. It is extremely important that you are familiar with them. Introduction to Plug-in Technology plug-in A program installed in the browser to extend its basic functionality. Allows different file formats to be viewed as part of a standard HTML document. As browsers have evolved, features that enhance their functionality have been included to support a large range of objects. Users can access the active content directly from the browser with plug-ins, such as Apple QuickTime and Adobe Flash players. Plug-ins, also called players, extend the capabilities of Web browsers. When you visit a Web site that requires a plug-in (or a more recent version of a plug-in that you already have installed), you may be prompted to download and install or reinstall the application so that you can view the Web page content properly. What are plug-ins? Plug-ins are applications associated with a specific platform (such as Windows or Apple OS X) and sometimes with a specific browser (such as Chrome, Firefox or Internet Explorer). The primary goal of a plug-in is to provide efficient integration of multimedia formats with the browser and computer. Without this integration, a user would have to download multimedia files and play them back later with a separate application. Plug-ins allow multimedia data types to execute directly from a browser, allowing immediate viewing and listening, thus enhancing your Web experience. Popular plug-ins include: OBJECTIVE : Plug-ins, addons and viewers Adobe Flash Player renders Flash animation files using streaming delivery. Microsoft Silverlight renders animation, vector graphics and multimedia files (audio, video) using streaming delivery. RealNetworks RealPlayer renders multimedia files (audio, video) using streaming delivery. Apple QuickTime renders multimedia files using streaming delivery. Windows Media Player renders multimedia files using streaming delivery.

9 Lesson 5: Multimedia on the Web 5-9 Firefox plug-ins are called add-ons. Firefox add-ons will be discussed in detail later in this lesson. Popular add-ons include: Live IP Address Flashblock User Agent Switcher WOT Web of Trust Flash Killer Firebug Zotero disk cache Storage space on a computer hard disk used to temporarily store downloaded data. streaming media A continuous flow of data, usually audio or video files, that assists with the uninterrupted delivery of those files into a browser. How do plug-ins work? When a browser encounters a file type that is not directly supported, it launches a plugin application that retrieves the multimedia files from a server, similar to the way a browser retrieves standard Web pages. The files are then delivered to the client system for playback. Instead of loading the entire file at once, many plug-ins retrieve a small portion at a time and store the data in the local disk cache. Using a cache, the plug-in delivers just enough information to build a continuous stream of data, called streaming media, which eliminates transfer delays. For instance, when you listen to a Web audio file, you may be hearing one part of the file while the next part downloads in the background. If you download an entire file before playing it, you are playing non-streaming media. Plug-in appearance Files that have been interpreted by a plug-in appear in one of three ways, depending on the file type and additional HTML tags. Some files will not function if additional HTML attributes are set. Following are the three appearance modes: Full-screen The multimedia will completely fill the browser window's inner frame. Embedded The multimedia appears as part of a larger document, in which the media or media player is visible as a rectangular sub-portion of a page. This mode resembles an embedded GIF or JPEG image, except the media can be live and/or dynamic, and may have its own embedded functionality. Many videos, such as YouTube or news story videos, are usually embedded files. The video is played within the browser window, as shown in Figure 5-2.

10 5-10 Internet Business Associate Video displays in this area Figure 5-2: Embedded video Musical Instrument Digital Interface (MIDI) A standard computer interface for creating and playing electronic music. It allows computers to re-create music in digital format for playback. Hidden The multimedia and its players are not visible in the browser and run in the background. An example of a commonly hidden plug-in is a Musical Instrument Digital Interface (MIDI) player. New window The plug-in opens in a new window, completely separate from the browser. The plug-in functions as a stand-alone application. The browser appears largely the same despite the plug-in. Basic browser operations (such as navigation, history, file opening and so forth) apply to all pages, regardless of which plug-ins are required to view each page. Data Compression and Decompression Before exploring particular audio and video player plug-ins, you should understand the basic principles of data compression. Compression is the reduction in size of data files. Audio and video files are compressed before they are transferred across the Internet to shorten the amount of time required to download them. Once files are received at the client system, they are decompressed so that they can be played (viewed and/or heard). There are various ways to compress data, and many types of data can be compressed. You are probably already familiar with popular "zip" programs that compress text and images. Some image file formats such as GIF and JPEG are designed to reduce the size of image files. lossless compression A type of data file compression in which all original data can be recovered when the file is decompressed. lossy compression A type of data file compression in which some file information is permanently eliminated. Compression can be either lossy or lossless. With lossless compression, all the original data can be recovered when the file is decompressed. Lossless compression is used for compressing text and spreadsheet files, for example. The Graphics Interchange File (GIF) format provides lossless compression. Lossy compression permanently eliminates some of the information (especially redundant information). When the file is decompressed, only part of the original information is still there. Lossy compression is used for video and sound files, where certain amounts of information loss is hard to detect and is therefore not noticeable. The JPEG file format, which is used extensively for photographs on the Web, uses lossy compression. When you save an image file in JPEG format, you can specify how much loss you want to allow. Generally, you must find a balance between image quality and file size.

11 Lesson 5: Multimedia on the Web 5-11 codec A compression/ decompression algorithm used by modern video and audio player plugins. Compression is performed by a program that uses an algorithm to specify compression or decompression instructions for a given file. Multimedia players (such as RealPlayer, Windows Media Player and QuickTime player) and HTML5 use special algorithms called codecs to create streaming media. Codec is an abbreviation for compression/decompression. Media files on the Web are compressed, and when you download them, they must be decompressed so that you can play them. Several standard codec schemes are employed on the Internet today, and new ones are added regularly. Players are equipped with these standardized codec schemes; as new codecs become popular, you can update your player's store of codecs. The store of codecs is updated when you upgrade your plug-in. Plug-in Installation OBJECTIVE : Plug-ins, addons and viewers Although plug-in installation procedures are quickly becoming standardized, unpredictable results can occur. This uncertainty exists because so many different configurations are possible depending on the user's choice of browser, operating system and plug-in. The two ways to install plug-ins are online and offline. Online installation Online installation usually occurs with the browser open. Although certain Firefox plugin installation files support online installation, many must be installed offline. Internet Explorer also installs many plug-in types without prompting the user when unsupported file types are encountered. Offline installation Offline installation requires the user to download the plug-in file, quit the browser and start the installation file. When installation is complete, the computer may need to be restarted before the changes take effect. In the case of offline installation, you must read the installation instructions carefully before starting the download. Installing and updating plug-ins Chrome, Internet Explorer and Firefox include several native plug-ins. The plug-ins are automatically installed with the browser. As mentioned earlier, when you visit a Web site that requires a plug-in (or a more recent version of a plug-in you already have), you may be prompted to download and install it. To avoid interrupting your Web browsing to download a plug-in every time you need one, you can visit several download sites in advance and install the most recent versions of popular plug-ins. It is advisable to occasionally upgrade plug-ins from the appropriate vendor's site. Upgrades usually include increased functionality and security updates.

12 5-12 Internet Business Associate Types of Plug-ins OBJECTIVE : Plug-ins, addons and viewers For many years, technology has allowed users to download and play back high-quality audio and video from the Internet. In the following pages, you will learn about several types of multimedia and their required plug-ins. Various plug-ins are available, and each one can handle different file types, with some overlap. For example, both QuickTime and Windows Media Player can play MP3 files. Most of these applications will prompt you to associate certain file types with the plug-in by default. The default association will display the plug-in icon next to the files of the associated type in Windows Explorer, and selecting an associated file will launch the default plug-in. However, you can still open a file using the non-default application. Adobe Flash Player The Adobe Flash Player allows browsers to view movies created with the Flash application. Flash movies offer full-screen navigation interfaces, are resizable to various display sizes and resolutions, and they can play as they download. vector graphics Resizable images that are saved as a sequence of vector statements, which describes a series of points to be connected. The Flash authoring software allows you to create animation by using vector graphics. Think of vector graphics as mathematical shapes. A vector graphic is saved as a sequence of vector statements, which describes a series of points to be connected. The graphics you are probably most familiar with, GIFs and JPEGs, are raster graphics, which are images that map bits directly to a display space (think of a grid of x and y coordinates on a display space). Raster graphics are pixel-based, and as such are much larger files than vector graphics. When the vector images are downloaded, they are rasterized (converted into raster images) as they arrive and the animation displays in the player. The advantages of using vector graphics are that the files are relatively small (resulting in shorter download time) and they are easily resized without affecting image quality. Flash files use an.swf file name extension. Flash has been ideal for the Internet; complex animations can be downloaded quickly because of their small file sizes. At the time of this writing, Google Chrome had Adobe Flash built in. Firefox and Internet Explorer require a manual installation. In the following lab, you will use the Flash Player with Mozilla Firefox. Suppose the marketing manager of your company wants to view Flash movies in his browser so he can decide whether to invest time and money to create similar products for the company Web site. You can download and install Adobe Flash Player in his browser so that he can view the files.

22 5-22 Internet Business Associate OBJECTIVE : Plug-ins, addons and viewers viewer A scaled-down version of an application; designed to view and print files. Types of Viewers A viewer is necessary to retrieve certain files when the program needed to open a file type is not installed on your computer. Viewers are scaled-down versions of applications and are usually available free of charge. They do not have the full application's functionality. Often, the viewer will allow you to view and print documents, but not edit them. Because viewer files are much smaller than program files, they are helpful when disk space is limited, or when the full program is unavailable. In this section, you will learn about two important viewers. Microsoft PowerPoint Viewer The Microsoft PowerPoint Viewer is a helpful tool for businesspeople who give slide presentations from laptop computers, or for users who have earlier versions of PowerPoint on their computers and must present slide shows created in newer versions. Installing the most recent version of PowerPoint Viewer ensures the ability to present a slide show created with any version of PowerPoint. PowerPoint Viewer can be downloaded and distributed freely from the Microsoft Web site ( You can also view PowerPoint slides directly within your browser. These file types are typically associated with your browser upon installation of either the browser or a new program. Adobe Reader Adobe Systems Incorporated offers a free viewer that can read files created in Adobe Acrobat. Because many files on the Web have been created in Adobe Acrobat, this viewer can be found on thousands of corporate Web pages. Portable Document Format (PDF) A file format that can be transferred across platforms and retain its formatting; designated by the file name extension.pdf. Portable Document Format (PDF) Adobe created the Portable Document Format (PDF), a general file format that can be created and read on any computer, regardless of the local operating system. These files are suitable for transmission over the Web. Because of their high compression and platform independence, PDF files take minimal time to download, even with slower connections. They also retain formatting information through all platforms. In the following lab, you will use Adobe Reader with Mozilla Firefox. Suppose the manager for a new Research and Development (R&D) project wants all the department personnel to be able to download and read PDF files. You can install Adobe Reader on the R&D team members' computers to enable each of them to do this. Lab 5-6: Installing and using Adobe Reader with Mozilla Firefox In this lab, you will download and install the current version of the free Adobe Reader, then use it to view PDF files in Firefox. Note: Students may require an account with administrative permissions to install this software. 1. First, you will download and install Adobe Reader. Open Firefox and go to to display the Adobe home page.

24 5-24 Internet Business Associate OBJECTIVE : Document and multimedia file formats Miscellaneous File Formats Files that you might download or use with plug-ins and streaming technologies include the following: Video Audio Graphics Documents Video files Some of the most commonly used video files on the Web today include (but are not limited to) files with the following file name extensions: Audio Video Interleave (AVI) Standard Windows file format for video files..avi Audio Video Interleave (AVI) files are standard video files for Windows. They are supported by Windows Media Player in Internet Explorer and by LiveVideo in Firefox. LiveVideo allows users to instantly view AVI movies embedded in Web pages, without downloading the files for later playback..mov the standard format for QuickTime movies, and the Apple OS X native movie platform. Another file name extension for QuickTime movies is.qt. Moving Picture Experts Group (MPEG) High-quality audio and video file compression format..mp4 MPEG-4 is a standard format for video on the Internet. The Moving Picture Experts Group (MPEG) is a standard for digital audio and video compression that provides extremely high quality and resolution. MP4 is supported by HTML5 video..ogg video format designed for HTML5 video. It is royalty-free and can be distributed without licensing fees..webm a royalty-free, open video and audio format designed for HTML5 video. The WebM format and its development is sponsored by Google. Audio Interchange File Format (AIFF) High-quality audio format developed by Apple Computer. AU Audio file format used by UNIX servers, the majority of Web servers. Most Web browsers can read AU. Waveform (WAV) Windows standard format for audio files. Audio files Firefox and Internet Explorer include native, or built-in, support for standard audio formats such as Audio Interchange File Format (AIFF), AU, MIDI (discussed earlier in this lesson) and Waveform (WAV). Users can play sound files embedded in HTML documents using their browsers, which automatically identify and play most major formats embedded in or linked to a Web page. Through connections to applications such as RealPlayer and Windows Media Player, browsers can also play MP3 files and other formats. The sound files you are likely to encounter on the Web include:.au audio format used by UNIX servers. Most browsers provide built-in support for AU files..aiff Audio Interchange File Format (AIFF), developed by Apple Computer, offers high-quality audio. Most browsers provide built-in support for AIFF files. The same programs that play AU files can be used to play AIFF files.

25 Lesson 5: Multimedia on the Web 5-25 MPEG-1 Audio Layer-3 (MP3) Popular compression standard for audio files; retains most of the sound quality of the source. Ogg Vorbis (.ogg) A free, open-source alternative to the MP3 compression format for audio files; creates smaller, faster downloading files..mp3 (abbreviation for MPEG-1 Audio Layer-3), a format for compressing audio files that uses the MPEG-1 standard and is supported by HTML5 audio. The MP3 format compresses audio files to one-twelfth the original size, shortening download times considerably. The original sound quality is preserved throughout the compression and decompression process. MP3 files are non-streaming (you must download them before you can play them). To listen to an MP3 file, you must download an MP3 player. Windows operating systems have built-in MP3 players. Many MP3 players are available as shareware and freeware on the Web. Any time a developer creates an application that uses the MP3 format, he or she must pay a license fee to use this format..ogg Ogg Vorbis, a free, open-source alternative to the MP3 format. In addition to not requiring a license, the Ogg Vorbis format uses a somewhat more efficient compression algorithm. Ogg Vorbis is discussed in more detail in the following section. It is supported by HTML5 audio..wav Waveform (WAV), the native sound format for Windows. Most browsers provide built-in support for WAV files. It is supported by HTML5 audio. Following is a brief list of software applications that can play audio files: Nullsoft Winamp ( plays a variety of formats Windows Media Player ( US/windows/products/windows-media) also supports many formats XMMS ( for UNIX-based systems (e.g., Ubuntu Linux) Vorbix ( for the Ogg Vorbis format on UNIX systems Ogg Ogg is a free, open-source alternative to the MP3 audio format (which is proprietary and licensed) and the MP4 video format. It uses the.ogg file name extension and is maintained by the Xiph.Org Foundation. The audio format is specifically called Ogg Vorbis. The Ogg format uses a somewhat more efficient compression algorithm than MPEG. Also, the creators of this format determined that certain frequencies can be dropped (lost) without affecting audio or video quality. Therefore, files are smaller, download faster, and sound as good as other formats. Windows Media Player and most Windows multimedia players do not natively support Ogg. However, you can load DirectShow filters to decode Ogg in them. DirectShow filters can be found at the Xiph.org site ( On Windows systems, the following players support Ogg files after DirectShow is installed: Windows Media Player Media Player Classic Core Media Player RealPlayer

26 5-26 Internet Business Associate Several Windows players do not require DirectShow. These players support Ogg by default: Winamp 5 and higher VLC media player On UNIX/Linux, use the following players for Ogg files: XMMS VLC media player For more information about the Ogg format, consult the Xiph.org site ( and the Ogg Vorbis site ( In the following lab, you will enable Windows Media Player to view Ogg Vorbis files. Suppose you have accessed a site that contains songs you want to hear, but they are all in the Ogg Vorbis format. You want to use the Windows Media Player that comes with Windows Vista. How can you view the files? Lab 5-7: Viewing Ogg Vorbis files in Windows Media Player In this lab, you will install the DirectShow filter required for Windows Media Player to play Ogg Vorbis files, then use the player to play a sample file. 1. First, you will install the DirectShow filter. Note: To save time, the DirectShow filter is provided with the supplemental files in the C:\CIW\Internet\Lab Files\Lesson05 folder. 2. Before you install the DirectShow filter, you must remove any existing Ogg Vorbis codecs. Go to Start Control Panel Programs Programs And Features. The Uninstall Or Change A Program window appears. Remove any Ogg codecs, if necessary. Close the Control Panel. 3. Ensure that the Windows Media Player is closed. 4. Open Windows Explorer and go to the C:\CIW\Internet\Lab Files\Lesson05 folder. Double-click opencodecs_ exe. 5. In the User Account Control dialog box that appears, click Yes. The Open Codecs Setup Wizard will appear. Take the steps necessary to complete the steps in the Wizard to install the codecs. Accept all defaults. 6. Click Finish when the installation is complete. Close the Notepad window that appears at the end of the installation process. 7. For the remainder of this lab to function properly, Windows Media Player must be your default audio player for Ogg files. Go to Start Control Panel Programs Default Programs, then click the Associate a file type or protocol with a program link. Scroll down and select the.ogg file name extension. Click Change Program, click Windows Media Player, then click OK. Repeat for the.oga file name extension, if necessary. When finished, click Close.

27 Lesson 5: Multimedia on the Web Next, you will view Ogg Vorbis files in Windows Media Player. Open Firefox and go to to visit the Vorbis.com site's music page, shown in Figure Notice that five sample tracks are available. Figure 5-15: Vorbis.com's music page 9. Click a link for any of the Ogg Vorbis tracks. One of two responses will occur: Windows Media Player will open and play the track, as shown in Figure Skip to Step 11. If it does not play, an Opening dialog box may appear. You must ensure that Windows Media Player is selected in the Open With drop-down list, then click OK. An alert message may appear stating that Windows Media Player does not recognize the file name extension of.ogx (the x is a variable). It will ask if you are sure the file is from a trustworthy source, and if you want to play it in Windows Media Player. If this message appears, select the check box for Don't ask me again for this extension (.ogx), as shown in Figure Figure 5-16: Configuring Windows Media Player to play.ogg files 10. Click Yes. Windows Media Player will open and play the track, as shown in Figure 5-17.

28 5-28 Internet Business Associate Figure 5-17: Playing an Ogg Vorbis track in Windows Media Player 11. Close the Windows Media Player window and the Firefox window. Converting media file formats For many types of video and audio files, proprietary formats are not cross-compatible. For instance, you cannot play a RealMedia file with Windows Media Player. Several shareware programs can convert various types of files. Video type conversion programs include the Free Video Converter Factory ( HAMSTER soft ( and Freemake Video Converter ( Audio type conversions are numerous. A few examples are MP3 to WAV, WAV to various compressed formats, or even one compressed format to another, such as MP3 to Ogg. For example, oggdec (an Ogg Vorbis tool) decodes an Ogg Vorbis file to a WAV file. Converting file formats that use lossy compression does not yield the best sound quality. Visit or to explore other tools you can use to convert media files. Graphics files Standard formats for graphics files use the following file name extensions. All of these formats can be viewed in browsers, and you can use several graphics programs (such as Photoshop or Paint Shop Pro) to modify and convert these files to other formats. Portable Network Graphics (PNG) An open source graphical image file format created to replace GIFs..png Portable Network Graphics (PNG) has become an Internet standard for graphics. It is a free open-source file format that can support 32-bit color palettes (nearly all colors) for graphics and photographs. PNG uses a bitmap format and was developed to replace the patented and limited GIF format.

29 Lesson 5: Multimedia on the Web 5-29 Graphics Interchange Format (GIF) A graphical image file format commonly used in HTML documents. Joint Photographic Experts Group (JPEG) A graphical image file format commonly used for photographs. Tagged Image File Format (TIFF) Commonly used graphic file format, developed by Aldus Corporation; uses the.tif or.tiff file name extension. Encapsulated PostScript (EPS) File format used for importing and exporting graphics..gif Graphics Interchange Format (GIF), previously one of the most common graphics file formats on the Internet. It has a patent, so anyone creating software programs that produce GIF files must pay a royalty. GIF is a bitmap format that uses lossless compression. It supports various resolutions, but is limited to 256 colors and is used most effectively for drawings and illustrations, rather than for photographs..jpg or.jpeg or.jfif Joint Photographic Experts Group (JPEG), a format widely used for photographs and complex graphics. This format supports 16 million colors and uses lossy compression. JPEG files can be relatively small. However, the developer must decide how much compression to use. The more compression, the smaller the file size, but the lower the image quality. The JPEG format does not work well with line drawings because not much data can be discarded during the lossy compression process, and the images lose sharpness and clarity..tif or tiff developed by the Aldus Corporation, which is now Adobe Software. Tagged Image File Format (TIFF) is a popular, customizable graphic format commonly used for medical imaging and desktop publishing. TIFF supports grayscale, 8-bit and 24-bit color, and monochrome formats. TIFF files are highresolution and very large in file size..ps PostScript (PS) files are written in a page description language so they are unreadable, and are designed for printing on PostScript printers..eps Encapsulated PostScript (EPS) is a file format that you can use to import and export graphic files between operating systems and applications. EPS is standard in the publishing industry. Whereas a PostScript file only has the instructions that determine the display of the graphic, an EPS file actually contains the bitmap information for the graphics file. This additional data allows EPS files to display an alternative bitmap graphic for previewing. EPS formats EPS provides three preview formats for graphics: PICT for Apple OS X systems TIFF for Windows-compatible computers EPSI, which is platform-independent Most of the time, the EPSI format is used to transfer a graphic from a graphics-editing application (such as Adobe Photoshop) into a page-layout application (such as Adobe PageMaker). EPSI is necessary because each application tends to use its own format. EPSI acts as an intermediary that ensures no information will be lost during conversion from one format to another. Document files Some of the common document file formats you may download from the Internet (or your company's intranet) use the following file name extensions:.txt a plain (ASCII) text file. These files can be viewed in your browser, or with a Word processor or text editor..pdf As you learned earlier in this lesson, PDF files can be read on any computer, regardless of the operating system. You need Adobe Reader to view PDF files, and a full version of Adobe Acrobat to create or modify PDF files..docx or.doc These files are usually created with Microsoft Word for Windows.

30 5-30 Internet Business Associate odt These files are usually created with Open Office Writer. Rich Text Format (RTF) Portable text file format created by Microsoft that allows image insertion and text formatting; an almost universal format..rtf Rich Text Format (RTF) was developed by Microsoft. Using RTF, you can insert images and format text. RTF is compatible with many operating systems and applications, including most OS X and Windows word processors. Most applications allow you to save files in multiple formats easily. For example, in Microsoft Word, you can select File Save As, then select PDF, RTF, DOC, DOCX, ODT, or TXT as the document type.

Exercise 5-2: File formats OBJECTIVE 1.5.7: Files and Web browsers Downloading Files with a Browser You can use various methods to download files from the Web using your browser. You can download Web pages (HTML files), image files, compressed files (ZIP files), various document types, MIDI files and so forth. However, remember that although you can download many things, that ability does not always make it acceptable to do so. Copyright infringement Keep in mind that copyright laws protect original works of authorship online as well as in print. Works of authorship include literary works (including computer programs); musical works; pictorial, graphical and sculptural works; motion pictures and other audiovisual works; sound recordings; and architectural works. Downloading songs and movies from the Internet without permission or payment is an illegal use of copyrighted material. Many photos and other images found on Web sites include copyright information or a request that you do not copy the work. If you want to use someone's copyright-protected material, you must contact the copyright owner and ask for permission. If you are granted permission to use the copyrighted work, the copyright holder determines the terms of use. For instance, there may be no cost, but you may be required to credit the owner for the work. If you use someone else's copyrighted material without obtaining permission, you are committing copyright infringement, which is a punishable crime. Saving Web site content You can save entire Web pages or elements of a Web page to your hard disk. You can choose different Save options depending on the elements you want to save. For example, you would use different commands to save an entire Web page than you would to save a graphic from a Web page. When saving a Web page to hard disk, most browsers save all related images, fonts and scripts referenced by the HTML on the page. You can open the page in your browser even when you are not connected to the Internet. When you download files to your hard disk, you are able to specify a destination directory. Be sure to remember where you store your downloaded files so that you can

31 Lesson 5: Multimedia on the Web 5-31 easily locate them when you are offline. In the next lab, you will save downloaded files to your class Downloads folder. You can also copy and paste text and images from a Web page into various types of documents, such as word-processing files or graphics files. Select the text and images you want to copy, then copy them to the Clipboard. Open the application into which you want to paste the text and/or images, then paste them into a new document. In the following lab, you will download and store Web site content using Mozilla Firefox. Suppose the marketing director of your company wants to study a page from a competitor's Web site on his laptop over the weekend without having to access the Internet to do so.
