Manually configure global system settings
Last Updated: July 07, 2026

When you log in the System tab on the left-pane is used to define global settings for the VUE system.

  1. Login to Element Manager, https://<VPS #2_IP_address>:5557.
  2. Click System > System Settings.
    Sub-MenuDescription
    Import buttonImports a stored configuration JSON file created with the Export operation.
    Export buttonExports the configuration to a JSON format file.
    Configure log levelsSet individual log levels for all system event containers. Refer to Configure log levels.
    License buttonGenerates a license request file and/or import a license response. Refer to Licensing.
    Status SaveSaves all the configuration to a JSON file. Typically used during upgrading the software.
    Submit buttonSaves all the configurations.
  3. Update values as necessary:
    ParameterDescription
    System NameVUE system name.
    Default Annex A Symbol RateThis is the default symbol rate for any output MPTS configured in Annex A. The EM automatically calculates the output TS rate when Annex A is selected as the output TS type. The default symbol rate is used for all Annex A streams when initially selected. Note that this is an EM only setting and only is used to select the output TS rate.
    HTTP Request Timeout

    Range: 0-30 seconds

    		Indicates the timeout value for VUE Controller waiting on VUE Server response to HTTP request in seconds. For a value of 0, VUE Controller uses the system defined timeout. The default value is 5 seconds.
    Multicast PSI loss timeoutDetection time in seconds for determining when the input PSI (PAT or PMT) is considered lost for multicast streams (broadcast/SDV).
    • Range: 0 - 21600 (seconds)
    • Default: 5 seconds
    • Special settings:
      • 0 = Disable multicast PSI timeout
    Unicast PSI loss timeout

    Detection time in seconds for determining when the input PSI (PAT or PMT) is considered lost for unicast streams (typically VOD).

    • Range: 0 - 21600 (seconds)
    • Default: 600
    • Special settings: 0 = disable unicast PSI timeout.
    • Notes: for VOD input streams, set to > 600.
    Input CC Error ThresholdThreshold setting for input continuity count alarm. This is the number of CC errors over a 5 second period before a CC error will be indicated. A setting of 0 disables the CC error checking.
    Output CC Error ThresholdThreshold setting for output continuity count alarm. This is the number of CC errors over a 5 second period before a CC error will be indicated. A setting of 0 disables the CC error checking.
    Time To LiveTime To Live (TTL) value of the IP packets sent from the Pipes for the transport streams.

    Range: 1 – 255

    Multicast input loss timeoutMaximum allowable time between packets for multicast streams before the stream is considered lost.
    • Range: 600 - 6000 (milliseconds)
    • Default: 5000
    • Notes: set in increments of 200 ms.
    Unicast input loss timeoutMaximum allowable time between packets for unicast input streams before the stream is considered lost.
    • Range: 600 – 6000 (milliseconds)
    • Default: 5000
    • Notes: set in increments of 200 ms.
    TS Redundancy AutoFallbackIf enabled, VUE automatically switch back to the primary TS while receiving from the secondary transport stream fails. This behavior results in the automated switching to the alternate input anytime the currently active input is failed.

    If disabled, VUE does not switch back to the primary TS though the secondary TS is failed.

    Input bit rate compare type

    Indicates whether to include null packets or exclude null packets when measuring the input bit rate of a TS.

    You can select compare type as StreamRate or DataRate. Default value is StreamRate.

    DAA
    VOD Reserved Port Mapped OTS Program

    The OTS reserved program number for VOD Mapping Operations. If set to a nonzero value, VUE will omit the program number from any VOD Mapping creations. A value of 0 has VUE use all program numbers.

    MTU Size

    Defines the output MTU size of packets in bytes. An MTU of 1500 supports DEPI output packets with up to 7 MPEG packets per Ethernet frame. An MTU of 2000 supports DEPI output packets with up to 10 MPEG packets per Ethernet frame.

    Default is 1500. This is the standard Ethernet frame size. To support a setting of 2000, all output interfaces in use must be configured to support an MTU setting of 2000. Do not change this setting without ensuring the corresponding output interfaces have been appropriately configured.

    Clear Buffer Reset CountsThis clears the internal pipe buffer reset counters to 0.
    DSCP
    Video PacketsThis is the output Ethernet DSCP setting for all video packets transmitted by the VUE system. Range is 0 – 63. Default is 38 (AF43).
    OOB/UEPI PacketsThis is the output Ethernet DSCP setting for all OOB packets transmitted by the VUE system. This is also used for all UEPI packets sent by the RxD and VARPD packets transmitted by the VUE. Range is 0 – 63. Default is 0 (CS0).
    GCP Communication This is the output Ethernet DSCP setting for all GCP communication between VUE and RxD. Range is 0 – 63. Default is 16 (CS2).
    HA Heartbeat CommunicationThis is the output Ethernet DSCP setting for all HA heartbeat communication between the VUE servers. VUE system. Range is 0 – 63. Default is 48 (CS6).
