  • PID Factory Default Settings for MPEG-2 Contribution Encoders

    The following manufacturers: Scopus, Tandberg, Harris, Tiernan, Link Research, NTT and Thomson, have agreed on a list of common PID factory default settings for MPEG-2 contribution encoders. The voluntary adoption of these settings will improve interoperability mainly during live contribution exchanges, when different encoders are used sequentially.

    These settings are available in new encoder products as well in older models through software upgrade. Please contact your vendor for more information.

    Please ensure that encoders used in the collection of news and events have the capability to default to these settings and that operations staff are familiar with their operation.

    The setting are:

    MPEG-2 Default PIDs for contribution

    PAT

    = 0x 0000

    PMT

    = 0x 0100

    VIDEO PID

    = 0x 0200

        PCR PID = 0x 0200 (embedded in Video PID)

    AUDIO I PID

    = 0x 1010

    AUDIO II PID

    = 0x 1020
