9 1 Introducing the LU500 This chapter introduces the LU500 Live Video Uplink unit and describes its hardware components. Overview The LU500 is a compact lightweight unit that enables you to transmit high-quality HD/SD video from diverse locations, while adapting to dynamic network conditions. The LU500 supports 4G (LTE, WiMAX) and 3G cellular, WiFi links and two Ethernet links. It weighs less than 1.68 kg (3.7 lb) with the battery, can be seamlessly connected to most commercially available cameras and comes with an easy-to-use touchscreen interface. Video Input Card Touchscreen Power ON/OFF DC Power Connector Figure 1: LU500 9

10 LiveU LU500 User Guide NOTE The LiveU Xtender is a lightweight external antenna unit that increases network reception and provides additional resiliency for live video transmission in extreme scenarios, such as heavily crowded locations. You can use this device to increase network reception of the LiveU LU500 units to which it is connected. Contact LiveU for more details about purchasing this option. The LiveU Xtender is described in the LiveU Xtender User Guide. After the LU500 powers up, it dials (connects) its modems to various networks (including WiFi) and combines their bandwidth into a single consolidated broadband uplink connection. The LU500 can then encode incoming video into an H.264 stream and transmit it over the aggregated bandwidth. NOTE The H.264 AVC high profile supports a 4:2:0 color space. At the receiving end, the LiveU LU2000 receives these various streams of video via a standard Internet connection. The LU2000 server runs multiple Multi-Media Hub (LU2000) instances. Each LU2000 recombines the streams received from a specific LU500 into a discrete broadcast-quality video stream that can be played out over an integrated SDI interface on the LU2000. NOTE Most popular SDI output resolutions are supported. The LU2000 is normally installed at a studio, broadcasting center or in a cloud server for online media. Figure 2: Solution Architecture Each LU2000 can be controlled and configured using a web portal called LiveU Central, as described on page

Short USB cable (Type A-to-Mini USB) for connecting another USB stick or modem to the LU500 Micro SD card, 8 GB, class10 Quick Start Guide 11

12 LiveU LU500 User Guide LiveU Central LiveU Central is a web interface that enables you to view LU500 status and to remotely configure an LU500 and an MMH instance (running on the LU2000 server). LiveU Central runs only in the Google Chrome, Internet Explorer or Firefox website browser. Each LiveU Central user is assigned permission to manage and control a specific group of LU500 units. Figure 3: LiveU Central When LiveU Central takes control of an LU500, the message Unit is under remote control is displayed on the LU500 unit. This popup notification remains on the LU500 screen until the LU500 user taps the Close button. This message provides an LU500 user with an indication that the LU500 is/was controlled remotely (and possibly that its configuration was changed). The LU500 user can tap this button at any time without affecting the control. NOTE An LU500 user cannot stop the LU500 from being remotely controlled. You may refer to the LiveU Central User Guide for more information. 12

13 2 Getting Started This chapter describes how to get started using the LU500, including powering on, connecting the camera, connecting to LU2000 (Multi-Media Hub [LU2000]) and broadcasting (playing). The following is an overview of the workflow described in this chapter. Connecting the Video Step 1 Page 14 Camera Step 2 Powering On the LU500 Unit Page 15 Step 3 Selecting a Channel Page 17 Step 4 Selecting a Profile Page 21 Defining Streaming Step 5 Configuration Settings Page 22 Step 6 Configuring WiFi Page 25 Step 7 Going Live Page 27 Step 8 Shutting Down Page 30 13

14 LiveU LU500 User Guide Step 1, Connecting the Video Camera The procedure for connecting a video camera to the LU500 is simple. Only one camera can be connected directly to the LU500 at a time. NOTE Optionally, you can order the LU500 with a special connector for mounting on a camera. There of two types of connectors used for this purpose: one with an Anton Bauer battery and one with a V-mount battery. If your LU500 has this special camera connector, then the Anton Bauer/V-mount battery powers both the LU500 and the camera. Another separate battery is not needed to power the LU500. The camera can be connected either before or after turning on the LU500. If you power on the LU500 before connecting the camera, then the message No camera connected is displayed. You can then connect the camera, as described below. To connect the camera: 1 Appropriate cables are provided for each type of camera. Connect one end of the appropriate camera s cable to the relevant port on the video camera. 2 Connect the other end of the cable to the appropriate port (SDI or HDMI) on the LU500 Live Video Uplink unit, according to the type of camera. Figure 4: LU500 Video Uplink Unit Connections 14

15 Getting Started Step 2, Powering On the LU500 Unit The following describes the procedure for turning on the LU500. The LU500 is provided by LiveU with a battery in its carrying case. If this is the first time that this LU500 is being used, then you may have to attach the battery, as described in the Attaching and Replacing a Battery section on page 72. Charging the LU500 We recommend charging the battery for at least six hours before using the LU500 for the first time. To charge the battery: Plug the AC Power Adapter into the DC Power connector on the LU500 while the battery is connected to the LU500. The small LED next to the connector should glow red, indicating that the battery is now being charged. Once the battery is completely charged, the LED glows green. It is good practice to keep the unit plugged into a power outlet when it is not in use in order to keep it charged and ready for operation. Make sure that the DC IN (power) connector is connected in the proper direction. Figure 5: DC IN Connection 15

16 LiveU LU500 User Guide To power on the LU500 unit: 1 Once the battery is fully charged, press and hold the power switch for approximately two seconds until the LU500 lights up. The entire boot-up and modem connection process typically takes approximately 60 seconds. Figure 6: Power Switch 2 If the camera is on and properly configured, then the LU500 screen should display the scene that the camera is capturing, as shown below: Figure 7: LU500 Main Screen A full description of the user interface is provided in Chapter 3, LU500 User Interface on page

17 Getting Started Step 3, Selecting a Channel Video is streamed from the LU500 system via the Internet to an MMH instance (running on the LU2000 server) using one or more networks (cellular modems, WiFi, Ethernet and so on, which are also called interfaces). The LU2000 is typically located at the broadcasting center or in the cloud. Alternatively, you can stream to a virtual channel, as described in the Virtual Groups section on page 19. Each LU500 uses a single channel for streaming over its interfaces to a specific LU2000. The LU2000 can service multiple channels (each channel is an LU2000 instance). The number of channels that it supports is dependent on the processing power of the machine on which the LU2000 is running. In order to connect to an LU2000, you must select the channel that the LU500 will use to communicate with it, as described below. This is a mandatory step the first time that you use the LU500. Afterwards, the LU500 uses the same channel unless you use the Channels button to change the channel. To connect to an LU2000: 1 Tap the up arrow on the bottom of the main screen, as shown below: Figure 8: Opening the LU500 Menu 17

18 LiveU LU500 User Guide The following screen is displayed: Figure 9: System Menu 2 Tap the Channels button to display the following screen: Figure 10: Selecting a Channel NOTE Virtual Groups are indicated by the icon. 3 Tap one of the channels to which you would like to stream. You can use the up and down arrow buttons to scroll through the channels. 18

19 Getting Started 4 Tap the BACK button to return to the main menu or the X to return to the main screen. The main screen should be displayed with a Ready button, as shown below: Figure 11: Ready to Go Live Virtual Groups The LU500 can stream to an output LU2000, as described on page 17, or to a Virtual Group. Streaming to a Virtual Group enables LiveU Central operators to preview the channel and then to control the destination to which the stream is ultimately directed and sent live. A LiveU Central operator can decide to stream to a physical SDI port on the LU2000 server or to a Content Delivery Network (CDN). When you select a Virtual Group, the video is initially streamed as a preview (virtual) channel to LiveU Central. In Preview mode, the video is transmitted as a light stream (at a low bandwidth and with a low resolution and frame rate). After a LiveU Central operator allocates a Virtual Channel in Preview mode to a destination, it is streamed at the defined resolution and frame rate. For more details about handling preview channels, see the LiveU Central User Guide. Virtual channels are indicated in the Channels screen by a green and blue icon, as shown below. Figure 12: Virtual Channel 19

20 LiveU LU500 User Guide When you select a Virtual Channel, the LU500 is in Preview mode. The word Preview is displayed in the button in the top-left corner of the screen, as shown below: Figure 13: Preview Mode To stop a Virtual Channel stream in Preview mode, click the Preview button. This returns the LU500 to Ready state and the video is no longer streaming. You cannot define when the Virtual Channel in Preview mode goes live. This can only be performed by a LiveU Central operator. When the LiveU Central operator defines that a Preview channel is live, the Preview button changes to Live, as shown below: Figure 14: Live NOTES When a LiveU Central operator changes a video stream from Preview to Live, that stream stops for a few seconds and then starts again. When the LU500 is streaming live to a Virtual Channel, the LU500 operator can click Preview to return the unit to Ready state. Alternatively, a LiveU Central operator can return an LU500 unit that is streaming to a Virtual Channel to Ready state by stopping the unit in the LiveU Central Devices tab. Refer to the LiveU Central User Guide for more details. When a LiveU Central operator defines that this channel is no longer live, then the button changes back to Preview. 20

38 LiveU LU500 User Guide Selecting the LU500 Profile Tap this button to display the following screen in which you can select the profile according to which the LU500 transmits: LIVE or Store & Forward. Figure 39: Selecting the Profile Live When this Profile is selected, the LU500 performs live streaming when the LU500 goes Live (as described in the Step 7, Going Live section on page 27). This is the default Profile. Video is streamed according to the delay that is selected in this window. To configure the Delay: Simply tap the + and buttons, as needed in order to adjust the delay value. Afterwards, the LU500 uses the same delay unless you change it. The following are the guidelines for selecting the delay that best suits your current delay versus quality requirements: Delay of 5 9 Seconds: This option generally provides the best of both worlds: lower delay and high-quality video. Delay of Seconds: Provides the maximum quality within the constraints of the shortest delay (between two to four seconds). This profile is resilient to changes (errors) and adapts quickly to bandwidth changes. Delay of Seconds: Prioritizes high-quality video over lower delay and is suitable for most purposes. 38

39 Store & Forward LU500 User Interface The Store & Forward profile defines that the LU500 stores the video on the micro SD card, while simultaneously uploading the stored video at the highest quality. This profile can only be selected in this window when the LU500 has a micro SD card inserted in it. Otherwise, this Store & Forward button is not active (grayed out). Figure 40: LU500 Micro SD Card Slot NOTE The micro SD card must be at least a 4GB, Class 10 SD card from an established manufacturer. The LU500 supports a micro SD card of up to 64 GB. The Store & Forward Profile is typically used when you are located in an area with limited bandwidth. It enables you to store the video on the LU500 unit and to transmit it as soon as reception has improved. When this option is selected, the Delay option is not active (grayed out). While this profile is storing and forwarding, the following message is displayed on the LU500 screen: HH:MM:SS estimated time left ##/## MB uploaded/total This message specifies the amount of time left to store this video and the number of MBs already transmitted out of the total current size of the video. After you stop camera videoing and while the LU500 is still forwarding the video, the following message is displayed: HH:MM:SS time to complete NOTE The delay cannot be configured during storing and forwarding, and is grayed out. 39

40 LiveU LU500 User Guide The Store & Forward Profile can also be used in areas of low or limited reception. In such cases, the video is stored on the SD card and can be transmitted once a cellular connection is available. This feature enables the Store & Forward Profile to be activated even when the unit is offline. You may refer to Chapter 4, File Transfer (FTP) on page 49 for more information about Store & Forward.

46 LiveU LU500 User Guide Satellite Mode LiveU currently supports the KaSat and BGAN satellites for its satellite streaming solution. Two modes of operation are available when working with satellites in the system: Satellite-only mode: In this mode, streaming occurs via satellite only. The LU500 must be configured to operate in this mode, as described below. When this mode is enabled on the LU unit, all interfaces except LAN interfaces are disabled on the unit (meaning WiFi and cellular modems). Hybrid mode: In this mode, the system uses both satellites and cellular modems for streaming. This mode is ideal when you want a satellite interface to serve as a backup for cellular modems. This mode is the default. There is no priority between cellular modems and satellite interfaces when working in this mode. If the bitrate on a cellular modem drops unexpectedly, the satellite interface is used instead. Both satellite and cellular modem interfaces can transmit simultaneously. Each satellite must be connected to a LAN port on the LU unit. The LU500 has two LAN ports (LAN0 or LAN1) and therefore enables you to connect one or two satellites. When using more than one satellite, the satellites are bonded together. To enable Satellite-only mode on the LU500: 1 Tap the up arrow on the bottom of the main screen. 2 Tap the Interfaces button to view the interfaces (cellular modems, WiFi, Ethernet and so on) of the LU500.

49 4 File Transfer (FTP) This chapter describes how to use the LU500 to transfer files from the field directly to a Multi-Media Hub (LU2000) running on an LU2000 server. Introduction The LU500 Live Video Uplink System enables you to transfer stored files to an LU2000. This feature can also be used to transfer any other type of file, such as text files, documents and so on. Files can be transferred from the LU500 unit s micro SD card or from a USB flash drive. NOTE The micro SD card must be at least a 4GB, Class 10 SD card from an established manufacturer. The LU500 supports a micro SD card of up to 64 GB. The files are stored on the LU2000 in the directory designated for this purpose. The files are organized in folders according to the LU500 unit that sent them. You may refer to the Managing MMH Files section in the LiveU Central User Guide for more information. Transferring Files To transfer files from the LU500 to an LU2000: 1 Select the channel (LU2000) to which you want to transfer the files, as described in the Step 3, Selecting a Channel section on page 17. NOTE Once you select a Virtual Group, you cannot perform a Store & Forward operation.

53 5 Interrupted Feedback (IFB) This chapter describes the LU500 s IFB Interrupted Feedback (IFB) feature and how to set it up. IFB Overview The IFB feature provides a unidirectional audio channel from the LU2000 to LU500 unit operators in the field. This enables the personnel in the master control room (MCR) to broadcast verbal instructions or information about events to LU500 operators. During broadcasting, LU500 operators can listen to an audio-only channel received from the IFB server using an earphone/headphone. IFB uses a unidirectional audio channel from the LU2000 to the LU500 unit, which only allows the LU500 operator to listen, but not respond. For more details about the IFB feature on the LU2000, see Appendix A, Interrupted Feedback (IFB) in the LiveU LU2000 Server User Guide. 53

54 LiveU LU500 User Guide IFB Setup Perform the following step before you start streaming, in order to ensure proper IFB operation. To set up IFB: Plug in the earphones/headphones into the microphone connector on the LU500. No other setup or configuration is required on the LU500. If the earphones/headphones are connected after streaming starts, the LU500 operator cannot hear anything on the IFB channel. Be sure to connect them before the streaming starts. During streaming, IFB uses a 600ms delay, which means that the LU500 operator hears the audio 6/10 of a second after the LU2000 operator speaks. 54

55 6 DataBridge Operation This chapter describes LiveU s DataBridge solution and how to operate the LU500 unit as a DataBridge. This chapter contains the following sections: LiveU DataBridge Solution, page 55 DataBridge Mode, page 57 LiveU DataBridge Solution LiveU s DataBridge solution enables point-to-multipoint transmission and reception of any kind of high-quality data from diverse locations, while adapting to dynamic network conditions. The DataBridge feature can be used for a variety of data connectivity solutions, such as for connecting a laptop in the field to a control station. The DataBridge solution is a client/server solution where an LU, such as the LU500, LU40, LU200 or LU400, that is configured to operate as a DataBridge unit, is the client and the DataBridge Gateway is the server. Cellular Core Networks UMTS Laptop EVDO Core Packet Switched Network DataBridge Gateway DataBridge EDGE Satellite Network Figure 55: DataBridge Solution Architecture 55

56 LiveU LU500 User Guide After the DataBridge unit powers up, it dials (connects) its modems to various networks and combines their bandwidth into a single consolidated broadband uplink and downlink connection: Transmitting Data: The DataBridge unit receives data from the user data equipment through its user port and transmits it over the aggregated bandwidth. Receiving Data: The DataBridge device receives incoming data through its aggregated bandwidth, and outputs it through its user port to the user data equipment. DataBridge Gateway The DataBridge Gateway server is located in the cloud, and receives various streams of data from the DataBridge unit through its network port, which is connected to standard Internet. The DataBridge Gateway server runs multiple remote connection instances. Each remote connection instance recombines the streams received from a specific DataBridge unit into a discrete high-quality data stream. DataBridge Unit Each DataBridge unit streams to a specific remote connection instance on the DataBridge Gateway. The DataBridge Gateway can service up to 100 DataBridge units simultaneously. The DataBridge unit: Employs proprietary algorithms to simultaneously break down and transmit data over multiple modems and to bond the data received over its multiple modems. Performs Layer 2 bridging by learning Layer 2 source addresses and forwarding according to Layer 2 destination MAC addresses. An LU500 working as a DataBridge unit operates in DataBridge mode. For more details, see the DataBridge Mode section on page
