Chapter 2 – Physical Interfaces This chapter describes how to connect your AV equipment to the encoder. Chapter 3 – Management Interfaces This chapter describes the management interfaces you can use to manage the encoder: Web Management Interface, AvediaServer Director application and admin interface. Chapter 4 - General Device Management This chapter describes general configuration of the encoder. For example, IP address configuration and the firmware upgrade procedure are explained here. Chapter 5 – Admin Interface This chapter describes how to configure the encoder using the serial Admin Interface. Chapter 6 - Encoding and Streaming This chapter explains how to configure the encoder to take accept the input of the AV source and convert this into an IPTV stream. Chapter 7 – Remote Control This chapter explains how to use the encoder to control the attached AV device. Chapter 8 - Status Monitoring This chapter explains how to check the operating status of the encoder. Chapter 9 – Troubleshooting This section provides troubleshooting information if you are having problems with the encoder. Administrator’s Guide 9 AvediaStream e25xx and e35xx Encoders V1.4 1 Getting Started AvediaStream Encoders create a single IPTV stream on your building, campus or metropolitan-area IP network from the output of various video devices. You can use them to distribute the output from a variety of Standard Definition and High Definition AV devices such as video cameras, DVD players, set-top boxes and professional SDI feeds. The AvediaStream e35xx encoders accept HD content inputs (up to 1080p 50/60Hz for e3532/e3535 and e3552/e3555) and allow full resolution encoding in the output transport stream. AvediaStream e35x2 encoders allow scaling of both resolution and frame rate in the output stream to values the same as, or lower than the input signal. The e3535 and e3555 allow scaling of any input to any output resolution and frame rate up to 1080p 50/60Hz. The AvediaStream e25xx encoders accept SD and HD inputs (up to 1080i) and deliver an SD (525i/625i) output transport stream. Refer to Table 5 on page 14 for more information about input resolution and frame rate capabilities. The following procedures must be performed for the encoder to perform correctly. These procedures are summarised in this section: 1. Connecting the AV Source Before the encoder can stream audio/video on the network, an AV source must be connected. See Physical Interfaces on page 12 for details on how to connect your AV equipment to the encoder. 2. Connecting to the Network Connect the encoder to the network. For more information, see the AvediaStream Installation Guide. 3. Connecting to Power Connect the encoder to a power source. For more information, see the AvediaStream Installation Guide. 4. Configuring the IP Address of the Encoder By default, the encoder requires a DHCP Server to be available on the network to assign it an IP address. There are two methods of assigning a static IP address to the encoder, if required: ● Use the serial Admin Interface to configure the IP address. For more information refer to Admin Interface on page 24. ● Temporarily set up a DHCP server on an isolated network. Once an IP address is assigned to the encoder, you can configure a static IP address using the Web Management Interface. For more information refer to Network Configuration on page 26. Allocating a static IP address for the encoder allows continued operation without a DHCP Server. 10 Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 5. Naming the Encoder Provide a name for the encoder so you can easily identify it in the future. This can be done using the Web Interface General Page (shown in Figure 12 on page 25) or the AvediaServer Director application (shown in Figure 10 on page 23). 6. Configuring Audio/Video Input The device starts encoding and streaming automatically when an appropriate AV source is connected. It may be necessary to configure the type of video source connected. Refer to Encoding and Streaming on page 37 for more information. 7. Configuring Encoding Options The device starts encoding automatically when an appropriate source is connected. Some aspects of the encoding can be configured if required. The encoder starts streaming (transmitting an MPEG transport stream on the IP network) automatically when an appropriate source is connected. Some aspects of the stream can be configured if required. For more information refer to Encoding and Streaming on page 37 and to Stream Properties on page 60. 8. Configuring Channel Announcements The encoder uses SAP (Session Announcement Protocol) to announce its stream (channel) to receiving devices. Included in the announcements are the name of the channel and the multicast address and port on which the stream is sent. This is done automatically once the encoder is up and running. You can configure channel announcements to suit your requirements. For more information refer to Channel Announcements on page 68. 9. Checking Status You can check the operating status of the encoder and that the encoder is transmitting data at the rate expected by the streaming settings. For more information refer to Status Monitoring on page 72. Administrator’s Guide 11 AvediaStream e25xx and e35xx Encoders V1.4 2 Physical Interfaces AvediaStream e25xx and e35xx encoders can operate in any of the following chassis: ● AvediaStream c1101 ● AvediaStream c1103 ● AvediaStream c1110 The encoder has AV interfaces on its rear panel, while its edge connector enables it to access network and admin ports via the chassis front panel. Caution: Take care not to touch the edge connector as static electricity might damage the product. Handle by the enclosure only and insert as soon as possible into the chassis. Chassis Interface The Encoder module provides the following interfaces over its edge connector to the chassis: ● Ethernet interface (10/100Mbps) ● Admin Interface ● Status LEDs ● Power supply The actual physical interfaces can be found on the chassis front panel. Please refer to the relevant AvediaStream Installation Guide for further details. Heartbeat LED The heartbeat LED (marked H/B) on the AvediaStream front panel provides an indication of the current state of the unit without using any of the management interfaces.

For example, you will find out how configure IP addressing, and how to upgrade firmware. All procedures described in this section assume that you are running the web management interface as described in Chapter 3 and all apply to the AvediaStream e25xx and e35xx encoders. About The Encoder You can find out specific information about the encoder from the General page in the web interface as shown in Figure 12. Much of this information is useful in identifying the software and hardware revisions in use in this module. If contacting technical support regarding a problem with the device, it can be useful to provide all this information. Software version: The version of software (often known as firmware) running on this device. Software description: A detailed version description identifying when the software was built. Serial number: The MAC address of the unit. IP Address: The IP address being used by the unit Hardware Type: This identifies the exact type of hardware module. Uptime: The length of time this device has been running since the last restart. Figure 12 General Page (e3520 shown) Administrator’s Guide 25 AvediaStream e25xx and e35xx Encoders V1.4 Device Naming The encoder can be assigned a name and location. The name and location can used to identify the device when multiple devices are installed. The name and location are also visible in the AvediaServer Director application. To specify the name and location: 1. Click General. 2. Enter a name and location as appropriate in the Name: and Location: fields. 3. Click the Apply button. Note: The name and location can also be configured on the Devices page in the AvediaServer Director application. Network Configuration This section describes encoder options relating to network connections. These options are all available from the Network page in the web interface shown in Figure 13. Figure 13 Network Page 26 Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 Device IP addressing You can configure the encoder to obtain an IP address automatically using DHCP, or you can specify static addressing information i.e. IP address, subnet mask and default gateway. Note: After applying an IP addressing change, this change takes effect after a short time and the device starts using the new IP address. No reboot is necessary. To configure the encoder to be allocated an IP address automatically: 1. Click Network. 2. In the IP Address Configuration section, click Automatically using DHCP. 3. Click the Apply button. To configure a static IP address: 1. Click Network. 2. In the IP Address Configuration section, click Manually using the following settings. 3.

Ethernet settings The encoder can automatically negotiate any combination of 10/100 Mbps and half/full duplex with an Ethernet switch. It is also possible to disable auto-negotiation, resulting in a fixed setting of 100Mbps full duplex (100FD). The default setting is On (Auto-negotiation enabled). It is important to ensure that the encoder settings match the settings on the switch port to which the encoder is connected. If this is not the case, the result can be dropped packets causing breakup of audio/video. In practice this means the AvediaStream encoder and the connected network switch should be configured for operation as follows: Auto-negotiation enabled on both the AvediaStream encoder and the connected network switch. Auto-negotiation disabled on both the AvediaStream encoder and the connected network switch, and a fixed setting of 100FD (Full Duplex) configured on the switch. It is not recommended that the encoder is connected to a half duplex Ethernet port. To enable/disable Ethernet auto-negotiation: 1. Click Network. 2. In the Network Port Configuration section, choose on or off as appropriate from the Auto-negotiation dropdown box. 3. Click the Apply button.

SDI Loop-through To enable the chaining together of additional equipment, the SDI input signal can be presented at the SDI output of the AvediaStream e2252/3550/3552 encoders using the Loopthrough function. When Loop-through is selected, the SDI signal at the input is passed to the output without modification. When Re-clocked loop-through is selected, the input signal is processed to reduce jitter. While the Re-clocked loop-through process delivers a better quality signal at the output, the timing is affected and the output signal is out of phase with the input. Simple Loop-through is more likely to suit environments where the timing of different SDI feeds is critical. The default setting is Disabled. To specify the SDI Loop-through: 1. Click Input. 2. Choose an option from the SDI Loop-through drop down list. 3. Click the Apply button. SD Video Aspect Ratio You can configure the aspect ratio to suit a 16:9 or 4:3 SD input signal.

The video can be encoded at constant bit rate (CBR) or variable bit rate (VBR). For a CBR stream, the encoding bit rate can be configured. For VBR, the maximum and average encoding bit rates can be configured. Note: It is possible that the configured bit rate may not be the bit rate used for the encoding, as the encoder has minimum and maximum limits based on the resolution of the connected video source. The actual encoding bit rate is displayed on the Status page. Refer to Status Monitoring on page 72 for more information. The default settings are: ● CBR 15Mbps - AvediaStream e2522, e2532, and e2552 ● CBR 20Mbps - AvediaStream e3520, e3522, e3530, and e3550 ● CBR 24Mbps - AvediaStream e3522 ● CBR 30Mbps - AvediaStream e3532,e3535, e3552 and e3555 For best picture quality, use CBR at the highest bit rate compatible with your system capacity. For best use of bandwidth use VBR and/or a lower bit rate, although this can result in degradation of picture quality. Encoding – AvediaStream e2522/e2532/e2552 By applying the H.264 Scalable Video Coding (SVC) extension capabilities of the e2522, e2532, and e2552, you can scale any input signal (up to 1080i 60Hz) and output it as an SD (525i/625i) transport stream with bit rates ranging between 2 and 15Mbps. You can manually select settings for the H.264 profile, the GOP Structure, and the Variable Length Coding Mode if required. However the default settings provide the optimum balance of picture quality and bandwidth in the output transport stream for the applied input. Encoding parameters are configured from the Encoding page on the web interface as shown in Figure 22.

Output Resolution and Frame Rates The scaling capabilities of the AvediaStream e3522, e3532, and e3552 encoders allow a variety of output resolutions and frame rates, depending on the applied input signal. Lowering the resolution to suit the output device enables you to reduce the bandwidth required in the output stream. However, this may affect the picture quality on high resolution displays. The Input-Output Resolution table shows the encoding output combinations (green tick marks ) and the possible combinations (grey tick marks ) for a specific input signal. All other combinations are invalid. Note: Progressive formats are required for scaling. A 1080i input can only be output at 1080i or at SD. For example, with no scaling selected the output resolution matches the input as shown in Figure 25. If an output scaled for iPhone4 (960 x 640) is required, the table indicates an input of 1080p or 720p is required. Figure 25 No Scaling Selected Administrator’s Guide 53 AvediaStream e25xx and e35xx Encoders V1.4 When scaling is enabled, you can also select the frame rate required, but only a value the same as, or lower than, the input signal frame rate.

The information in the announcements includes the multicast address and port of the stream and enables client (receiver) devices to attach to the stream. SAP announcements are sent to multicast address 239.255.255.255, port 9875. The options described in this section allow some additional information to be put into the announcements. It is also possible to disable the sending of announcements. Announcements are configured using the web interface Announcements page as shown in Figure 35. Figure 35 AvediaStream e3520 Announcements Page Channel name The channel name will be used by Exterity IPTV receivers and PC clients to identify the channel. The default channel name for the AvediaStream e3520 is “AvediaStream e3520 xxxxx”, where “xxxxxx” is the last six digits of the encoder’s MAC address. The AvediaStream e2522, e2532/e3530/e3532, e2552/e3550/e3552 and e3535/e3555 are similar. This can be changed as required. To specify the channel name: 1. Click Announcements. 2. Enter the desired name in the Channel Name box. 3. Click the Apply button. Channel number The channel number will be used by Exterity IPTV receivers and PC clients to produce an ordered list of channels. The default channel number is 0. To specify the channel number: 1. Click Announcements. 2. Enter a value between 0 and 999 in the Channel Number box. 3. Click the Apply button. Groups The available channels across a network of Exterity devices can be split into groups of similar types. For example, you might have a group of Sports channels and a group of Children’s channels. Channels are assigned to group(s) by the AvediaStream encoders. The group name is included as part of the SAP announcements and allows Exterity receivers and PC clients to list only channels in a particular group or groups. 68 Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 Assign the channel provided by your encoder by entering the group name. You can assign it to more than one group by entering a comma-separated list of groups. The default value is all, meaning that its channel is available to all groups. To add the device to a group or groups: 1. Click Announcements. 2. Enter a comma separated list of group names, for example; teachers,administrators in the Groups box. 3. Click the Apply button. Note: When entering a list of group names as a comma separated list, ensure there are no spaces in the list. To remove the device from every group (i.e. add the device to the all group): 1. Click Announcements. 2. Enter all in the Groups box. 3. Click the Apply button. Announce Using SAP This option allows the administrator to turn on/off channel announcements. To configure the announcement setting: 1. Click Announcements. 2. Check or un-check the Announce Using SAP box as appropriate. 3. Click the Apply button. Administrator’s Guide 69 AvediaStream e25xx and e35xx Encoders V1.4 7 Remote Control The AvediaStream e2522/e3520/e3522 and e2532/e3530/e3532 encoders can send infra-red remote control commands to the attached AV source. These commands are sent based on commands received over the network from an IPTV receiver. To do this it is necessary to obtain a configuration file with the remote control codes for that particular device. Note: The AvediaStream e2552/e3550/e3552 encoders do not support IR remote control functions. Figure 36 IR Remote Control of AV Source This capability is shown in Figure 36 where, for example, the remote control handset could be used to play/pause/stop the DVD player. Remote Control is configured using the web interface Remote page as shown in Figure 37. Figure 37 AvediaStream e3530 Remote Page 70 Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 IR Configuration File In order to use the infra-red transmitter to control the AV source, it is necessary to obtain a configuration file with the remote control codes for that particular device. Contact your Systems Integrator or Reseller in order to obtain a configuration file. To download an IR config file: 1. The device uses TFTP to download new remote control config files from a TFTP server. To update the config file, first ensure that the correct TFTP server IP address is specified in the Maintenance page, and that the TFTP server is running. 2. Save the configuration file in the following directory on the TFTP server. <root>/remotes/<manufacturer>/<type>/<manufacturer>_<type>_<id>.conf For example: <root>/remotes/mybrand/dvd/mybrand_dvd_2.conf 3. Click Remote. 4. Enter the name of the configuration file in the IR Remote Control Type box. 5. Click the Apply button. The new configuration file is downloaded automatically from the TFTP server. Master IR Client By default, any device on the network can send remote control commands to the encoder. To allow only one device to do this, configure that device as the Master IR Client. To specify the master IR client: 1. Click Remote. 2. Enter an IP address in the Master IR Client Address box. 3. Click the Apply button. To remove the master IR client: 1. Click Remote. 2. Enter 0.0.0.0 in the Master IR Client Address box. 3. Click the Apply button. Administrator’s Guide 71 AvediaStream e25xx and e35xx Encoders V1.4 8 Status Monitoring This section explains how to check the operating status of an AvediaStream encoder. You can see both configured and detected information and check, for example, if the encoder is streaming the signal applied to the input. Status information is displayed on the web interface Status page shown in Figure 38 and is described for each encoder in sections: ● Status – AvediaStream e2522/e3520/e3522 on page 73 ● Status – AvediaStream e2532/e3530/e3532/e3535 on page 76 ● Status – AvediaStream e2552/e3550/e3552/e3555 on page 79 Figure 38 AvediaStream e3520 Status Page 72 Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 Status – AvediaStream e2522/e3520/e3522 The AvediaStream e2522/e3520/e3522 status information is displayed on the web interface Status page as shown in Figure 39: Figure 39 AvediaStream e3520 Status Page Stream The detected streaming status is displayed with the following values: Stream value Description Started The unit is currently streaming Stopped User has stopped streaming or has not attempted to start streaming. Waiting for video source The encoder has been unable to find a suitable video source. Check the video cable(s) has/have been correctly attached to the unit and that the video source is turned on and working.

Larger differences may cause the encoder to lose, or not achieve synchronisation. Typically this is due to a 24Hz/60Hz input applied while a 23.98Hz/59.94Hz frame rate is configured on the web interface Input page, or vice versa. Check the source and encoder settings to resolve the mismatch. Actual Video Rate Displays the Actual Video Rate, which is determined by the input/source present and the Video Bit Rate configured on the Encoding page. Configured Value Detected Information CBR CBR: bit rate VBR VBR: max bit rate, average bit rate The encoder uses a range of video rates, depending on the connected input/source. For example, if the Video Bit Rate is configured to 20Mbps but an SD source is connected, the actual video bit rate will be 10 Mbits/s. For more information refer to Encoding on page 47.

To view network port utilisation, go to the Network page on the web interface. The Ethernet interface statistics are shown at the bottom of the page. The transmit utilisation should approximately match the rate specified on the Stream page. You would normally expect to see very little traffic on the receive side. Figure 43 Network Statistics Administrator’s Guide 81 AvediaStream e25xx and e35xx Encoders V1.4 9 Troubleshooting Problem Possible Cause Solution Device does not appear in the AvediaServer Director application. Network connection faulty or cannot obtain IP address. Check Ethernet connections or replace cable. Check that DHCP Server is running on network. Check switch settings match unit Ethernet settings. The AvediaServer Director application cannot communicate with device. Encoder does not appear to be streaming. Device is definitely streaming but client cannot connect to stream. Device is streaming but video and or audio is broken up on client. 82 PC has firewall configured, blocking SNMP traps. Disable firewall, or configure firewall to allow UDP port 162 traffic to this application. PC has another application listening for SNMP traps. Close down SNMP trap listener. Network connection faulty. See above Device has an IP address on a different subnet to the management station. Use a management station configured with an appropriate IP address to manage the device. Device is upgrading (indicated by alternately slow and fast LED flash). Wait for upgrade to complete. AV source not connected or powered off. Check connections and power to AV source. Check the status page to see if the encoder thinks it is attached to a valid video source. Video input setting wrong. Check the video input setting matches the AV input to the encoder. The cabling is incorrect e.g. the Y cable is not attached to the Y BNC. Check cabling. Multicast address is not unique. Particularly if the multicast address was assigned manually, check it is unique. Client cannot accept H.264 Update the client software or use a different client to view the stream. If using PC client, PC Firewall is preventing video traffic. Disable firewall, or configure firewall to allow traffic to this application. Network is not IGMP enabled. Check the configuration of the network switch(es). Check the switch(es) for errors. Administrator’s Guide AvediaStream e25xx and e35xx Encoders V1.4 Encoded output is a solid colour, green or black most common, with no audio. After upgrade, the device is still running the old version of firmware. Board temperature more than 20 degrees centigrade above ambient temperature. Administrator’s Guide The streaming bit rate exceeds the capability of the client. Lower the encoding bit rate. Connection may be HDCP protected. AvediaStream e3532 - check the Stream and Video Input conditions on the web interface Status page for copy protection detection. HDCP enabled DisplayPort, HDMI, or DVI connection. Test the configuration using known non-protected program content The correct firmware file is not on the TFTP Server. Put the correct file on the TFTP Server. The TFTP Server address configured for the device is wrong Check that the TFTP Server address is the address of the machine the TFTP Server is running on. The TFTP Server is not running. Start the TFTP Server. The TFTP Server is not configured to send files. Fix the security settings on the TFTP Server. Air vents are blocked. Check that air vents are not blocked. Fans have stopped running. Check that fans are running. None of the above. If the problem persists, switch off the unit and contact your Exterity systems integrator or reseller. 83 AvediaStream e25xx and e35xx Encoders V1.4 APPENDIX A Serial Interface Connection The serial admin interface provides the ability to manage a small subset of device functionality e.g. to configure an IP address. Cabling To connect to the serial interface use the DB-9 – RJ45 adaptor supplied by Exterity (shown in Figure 44. Figure 44 DB-9 to RJ45 serial adaptor The female DB-9 connector should be plugged into the serial port on a PC. A straight-through network cable should be used between the RJ45 socket on the adaptor and the admin port on the Exterity device. Note: Although the cable fits, the admin port should not be connected to the Ethernet port on a PC.
