The first UDP port along with the number of VOD mappings is defined by the user. This determines the UDP ports opened by the VUE server. Up to 32 mappings per output stream can be created.
Use the following table as a guideline to determine the starting UDP port number. This table uses the VOD Extended 10/6 algorithm.
Make sure there is a match between the VOD server and VUE server.
| OTS | Start UDP | TS # (hex) | MPEG PN (hex) |
|---|---|---|---|
| 1 | 1041 | 41 | 1 |
| 2 | 1081 | 42 | 1 |
| 3 | 10C1 | 43 | 1 |
| 4 | 1101 | 44 | 1 |
| 5 | 1141 | 45 | 1 |
| 6 | 1181 | 46 | 1 |
| 7 | 11C1 | 47 | 1 |
| 8 | 1201 | 48 | 1 |
| 9 | 1241 | 49 | 1 |
| 10 | 1281 | 4A | 1 |
| 11 | 12C1 | 4B | 1 |
| 13 | 1301 | 4C | 1 |

- Login to Element Manager, https://<VPS#2_IP_address:5557>.
- Click VOD on the left navigation pane.
- Choose the specific server on which you want to create the transport stream from the drop-down list.
- Click
to configure VOD transport stream. - Enter the stream values as necessary in the dialog that opens:
Parameter Description Name (Optional)
Enter a unique descriptive name. The name is a case-sensitive string of up to 32 characters. Valid characters are:
a-z, A-Z, 0-9, @, +, #, _ (underscore), and - (hyphen).
Destination IP Enter the destination IP address of the transport stream. This may be a multicast IP or a destination IP for a unicast stream. Destination UDP (Range: 1 – 65535)
Enter valid UDP Port number if this is a non-DEPI output stream. PAT TSID (Range: 0 – 65535)
Enter a valid Transport Stream ID. Session ID (Range: 0 - 0xFFFFFFFF)
This is the unique hexadecimal session ID for this output stream. Use the session ID that matches the session ID of the QAM channel where the DEPI transport stream is destined. TS Info Rate (Mbps) (Fixed)
Default is Annex B rate of 38.8107Mbps. The default setting should be used unless you desire to output a stream to an Annex A or C downstream device. Use Annex/Symbol Rate Enable this setting to specify the Annex mode (A, B, or C), modulation mode (QAM64 or QAM256) and the symbol rate of the output stream. VUE uses these 3 parameters to determine a more precise output rate to match the RxD. Disable this setting to manually set the output TS information rate in Mbps.
Annex Mode (Range – A, B, or C)
Set Annex mode based on desired output rate. Only used when symbol rate is non-zero. Default is Annex B (38.8107 Mbps). When set to Annex A or C, you can use the calculator on the EM to easily select an output TS rate. Modulation The modulation mode used on the QAM interface. Supported values are QAM256 or QAM64. The default value is QAM256. SymbolRate (Msps) (Range 0, 0.8 – 6.952 Msps)
The symbol rate (Msps) to be used for the MPEG video. The default is 0. When symbolRate is nonzero, the fixed information rate of the output transportStream is calculated based on the modulation (default QAM256), symbolRate and annex (default B) attributes instead of the tsInfoRate attribute. Mute Output TS Unchecked or disabled by default. Check this box to prevent the output stream from being transmitted to the RPD. The mute function mimics an EQAM channel mute capability. Enable DEPI Check this box to enable if the VOD transport stream is intended to be transmitted to an RPD. Output Interface IP Select the output interface IP from the drop down menu. This defines the output IP along with the VUE server to send the output stream.
If VUE server is part of a redundancy cluster this must be a VIP.
NOTE:If you have selected a specific VUE server from the drop-down list, then only the output interface IP of that server will be available.
The type of IP selected (IPv4 or IPv6) must be the same as the type of destination IP entered. For example, if an IPv6 multicast destination IP was entered, the selected interface IP must be an IPv6 address. If destination IP is an IPv4 address, then the selected interface IP must be an IPv4 address.
Input Virtual IP Select one of the Virtual IP addresses to receive VOD from the drop-down. This is the input address from which the VUE will receive singlecast UDP streams for the specified UDP ports. NOTE:If you have selected a specific VUE server from the drop-down list, then only the input interface IP of that server will be available.
First UDP Port (Range: 1024 – 65535)
Define the first UDP Port to use for VOD content. This is the first UDP port to listen to in a series of sequentially increasing UDP ports. UDP ports opened will increment by 1 starting with this UDP port. Mappings 0 – 32
Enter the number of VOD mappings. For every mapping, the VUE will listen to one UDP port starting with the First UDP Port defined. Last UDP Port This is display only field and is calculated by VUE based on the previous two parameters. NULL PID BW (bps) (Range: 0 - 1,000,000 bps)
(Optional)
This is an amount of NULL BW to reserve on a TS. This ensures that the TS output will include an amount of NULL BW. Setting this incorrectly can result in dropped PSI and data/video packets. NOTE: There will be a momentary loss of video when the TS info rate, annex mode, symbol rate, or modulation mode is modified. You should only modify parameters that impact output TS rate during a maintenance window. - Click Submit to apply the VOD settings or Cancel to disregard the changes.
- To see the list of programs and their status for each VOD transport stream, click the number under Mappings column displayed for each VOD entry. This opens the VOD Mappings window listing all the programs created for that VOD transport stream. Each one of these programs has a selection for input stream status, output status, and overall input/output packet statistics.
