2 Agenda Video Basics The Internet & IP IPTV Internet TV What s next? Page 2

3 Information Transmission Information Must Converted to be Converted to be Compatible with the Medium Voice -> PCM -> TDM Video -> >QAM -> Coax Various Methods of Conversion Improve Efficiency Allow Processing Provide for Error Correction Page 3

4 Information to Transmit Communications Networks Transmit Many Forms of Information Voice Video Web Pages Documents Telemetry Signals Music Text Messaging Page 4

5 The Internet Widespread Use of the Internet has Made the Internet t Protocol (IP) the Transmission i of Choice Global Access Inexpensive Transport Adapted to use with time-sensitive traffic Page 5

6 Page 6 IP Some of the Basics

7 History of the Internet Created by US Department of Defense in 1969 Wanted a communication system that could not be destroyed by a catastrophic event Page 7

8 Internet History 1957 ARPAnet The geography of the growing ARPANET in June The network has 57 nodes. Page 8

9 OSI Model No Network Discussion is Complete without Mentioning i the OSI Model OSI = Open System Interconnection Defines a networking framework for implementing i protocols Uses seven layers Page 9

10 OSI Model Translating and Coding Policing oc Data broken down into manageable chunks Adds addressing information Data is packaged into frames Page 10

11 What is IP? Internet Protocol (IP) Method (or protocol) by which data is sent from one device to another Each computer on a network (such as the Internet) At least one IP address Unique ID(s) Information ( , Web page, video, etc.) is divided into little chunks called packets. Page 11

12 IP Addressing (Cont) First Bits Used to Define the Network Like the Zip Code or City Last Bits Used to Define Client On Network Like the Name Note: Larger cities need more bits to uniquely identify their citizens. Page 12

13 Options Deliver the Packet Don t Care about Errors User Datagram Protocol (UDP) If the Packet has Errors, Request Another Until it is Correct Transmission Control Protocol (TCP) Page 13

14 UDP Communications UDP User Datagram Protocol No guarantee of delivery When is this useful? Page 14

15 TCP Communications TCP Connection oriented Guaranteed delivery When is this useful? Hey you! I am gonna send you data ` Hold on a second. I am busy PC 1 OK Okay, go ahead and send Here ya go! DATA DATA DATA Hey, I missed part of that last data PC 2 No problem. I will re-transmit it Okay, now I received it all Page 15

16 Video Basics Page 16

17 MPEG-2 Video Frames I-Frames Coded d using information present only in the frame itself P-Frames Coded with respect to the nearest previous I or P Frames B-Frames Use both future and past frames as a reference Page 17

18 The Future of MPEG2 & MPEG4 12 The Future of MPEG2 & MPEG MPEG2 SD MPEG4 SD H.264 MPEG4 HD H.264 Mbps Year

20 In Comparison what is IP Video (Video over IP) It should have been called VoIP but that was already taken by some other technology Myths: IP video is available for anyone with an Internet connection. IP video and Internet video are the same thing. IP video is easily hacked and pirated. Facts: We re running out of acronyms. Page 20

21 Video over IP IP is just the transport mechanism (or protocol) MPEG-2 / IP MPEG-4 / IP Provided by a local service provider Similar to a CATV system Page 21

22 IPTV Architecture Page 22

23 Middleware Page 23

24 What s the Difference? IPTV or Internet TV? If you recall Internet Protocol (IP) is the method (or protocol) by which data is sent from one computer to another on the Internet. t In this case, video (data) is requested by the computer (STB) and sent via IP which is a transport method not a transport pipe. Page 24

25 The difference is the source Page 25

26 IPTV vs. Internet TV Characteristics IPTV Video content aggregated by local provider High quality maintained throughout the network Subscription service Best for live events Internet TV Video content aggregated by national Internet companies Quality of video driven by speed of internet connection Typically free or charged per video Best for on demand content Page 26
