Configure RPC DEPI transport stream
Last Updated: July 07, 2026
When you create a Downstream External PHY Interface for Remote Procedure Call Switched Digital Video, you define a transport stream configuration for video traffic. This stream configuration is advertised for Switched Digital Video systems and sent to Remote PHY Devices for QAM upconversion. This procedure assumes that you are logged in to the EM.
  1. Login to Element Manager, https://<VPS#2_IP_address:5557>.
  2. Click on the 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 new transport stream.
  5. Enter the stream values as necessary in the Add Transport Stream dialog that opens:
    ParameterDescription
    Transport Stream TypeChoose RPC 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 is non-editable.
    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.

    Input Port IndexChoose the RPC input port number associated with this Data Plane IP entry and is only used when the SDV Operating Mode is RPC.
    PAT TSID

    (Range: 0 – 65535)

    		Enter a valid Transport Stream ID.
    TS Info Rate (Mbps)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 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.
    Symbol Rate (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.
    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/RMD. 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. Recommended to leave this setting enabled.
    Reuse Input PAT TSID

    If 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.

    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.
  6. Select the RPC DEPI stream type from the Transport Stream Type pull-down menu.
  7. Click Next to move to the RPC DEPI configuration steps. Enter the remaining RPC DEPI parameters and complete the configuration:
    ParametersDescription
    LSMSelect to enable linear source management.
    Session ID

    (Range: 0 - 0xFFFFFFFF)

    		The unique hexadecimal session ID for this output stream. Use the session ID that matches the session ID of the QAM channel for which the DEPI transport stream is destined.
    Group NameThis must match what is entered on the ERM (128 character string name).
    RPC Service GroupA name identifying the RPC service group of the Transport Stream with maximum for 128 characters.
    RPC Output Port NumberRPC channel output port number for this transport stream when RPC session management is used for mapping creation. The value must be set to greater than 0 for RPC controlled session mapping.
    Frequency (MHz)This is the QAM frequency in MHz used by the transport stream is as transmitted by the RPD. This value is sent to the SDV system.
  8. Click Submit to create the RPC DEPI transport stream.
    Click Back to go back to previous screen or click Cancel to disregard the changes.
This procedure completes the creation and configuration of an RPC DEPI Transport Stream.
