Create a SCTE 55-1 transport stream
Last Updated: July 07, 2026
Create an MPTS DEPI transport stream for transmission directly to a Remote PHY Device.
  1. Login to Element Manager, https://<VPS#2_IP_address:5557>.
  2. Click Transport Stream on the left navigation pane.
  3. Choose the specific server on which you want to create the transport stream from the drop-down list.
  4. Click Add icon to create a transport stream.
  5. Enter the stream values as necessary in the Add Transport Stream dialog that opens:
    ParameterDescription
    Transport Stream TypeChoose MPTS DEPI from the drop-down list.
    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 IPEnter multicast IP address of the RPD or RMD that will receive this MPTS. Typically set to an IPv6 multicast IP when transmitting to an RPD or RMD.
    Destination UDPDefault value is 1. This field in non-editable. Not applicable here.
    Output Interface

    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.

    PAT TSID

    (Range: 0 – 65535)

    		Enter a valid Transport Stream ID.
    TS Info Rate (Mbps)Default is Annex B rate of 38.8107Mbps. Recommend to leave this setting unchanged unless you desire to output a stream to an Annex A or C downstream device.
    Use Annex/Symbol RateEnable 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.
    ModulationThe modulation mode used on the QAM interface. Supported values are QAM256 or QAM64.
    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: Necessary only when the VUE is connected to a downstream RMD.
    Mute Output TSUnchecked 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.
    PID RemappingDefault is set to enable PID Remapping. This will ensure the output PIDs are unique for each program created. It is recommended that you leave this setting enabled.
    Reuse input PAT TSIDIf enabled, follows the input TSID value for an auto-mapped input transport stream when creating an Output TS.

    If disabled, configured value of the PAT TSID will be inserted in the Output TS.

  6. Click Next to go the next transport stream screen.
  7. Enter the remaining MPTS DEPI parameters and complete the configuration:
    ParameterDescription
    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.
    Output Stream TypeSelect Video (leave this set to Video).
  8. Click Submit to create the Transport Stream.
    Click Back to go back to previous screen or click Cancel to disregard the changes.
