  3. MPEG-TS input configuration

    1. Task creation

      1. Click on "Live Tasks" button, select "Tasks Map" in the list and click on "New" button.
      2. Give a name to the task.

      3. Select the task. In "Input" panel, set "Input mode" to "TS".
    2. Basic configuration

      • From "TS input" panel, select desired ethernet interface, set source IP address and UDP port.

        IGMPv3 is supported. SSM (Source Specific Multicast) address can be configured.

      • From "Input PIDs" panel, set "PIDs selection mode" to "manual", and configure video and audio PIDs.

    3. Redundant sources

      Redundant sources settings are configurable from "Input" > "TS Input" panel when task is deactivated (not runinng) and from "Operation" > "Source switching" panel when task is running.

      • "Manual" switching mode

        Into this mode, a manual operation is required to switch between redundant sources.

        From "Input" > "TS Input" panel:
        • Set "Switching mode" to "Manual"
        • Add redundant sources
        • Configure source settings (Ethernet interface, IP address, port...)
        • Configure desired source at task activation
      • "Automatic with manual switchover" switching mode

        Into this mode the task automatically detects signal loss on the current source according to the "Detection Threshold" value. It switches automatically to redundant sources.
        If all redundant sources are missing, a manual action is required for switchover to a valid source.

        From "Input" > "TS Input" panel:
        • Set "Switching mode" to "Automatic with manual switchover"
        • Add redundant sources
        • Configure source settings (Ethernet interface, IP address, port...)
        • Configure desired source at task activation
      • "Automatic switchover" switching mode

        Into this mode the task automatically detects signal loss on the current source according to the "Detection Threshold" value. It switches automatically to redundant sources.
        If all redundant sources are missing, the task will switch periodically between all redundant sources until data is detected.

        From "Input" > "TS Input" panel:
        • Set "Switching mode" to "Automatic switchover"
        • Add redundant sources
        • Configure source settings (Ethernet interface, IP address, port...)
        • Configure desired source at task activation
      • Slate picture insertion

        In the event of source signal loss, the task can switch automatically to a slate picture.

        • In "Video processing" > "Slate" panel, load slate picture. (BMP, JPG or PNG file)
        • In "Input" > "TS Input" panel, set "Switching mode" to "Automatic switchover" and set source type of last redundant source to "Source from Slate".

          Task automatically switches to slate picture if all redundant sources are missing.

          Task automatically switches from slate picture to a valid source as soon as one of the redundant sources is available.

      • Source switching operations while task is running

        To switch between sources while task is running, from "Operation" > "Source switching" panel, select "Desired source" and click on "Apply changes" button.
    4. PIDs selection modes

      • Manual selection mode

        The operator sets the PIDs manually from "PID scanner" information.

        • Video PID to convert: Select input video PID to process.
        • Audio PID to convert: Select input audio PID(s) to process.
          • Delay: Audio delay control (-125ms to 125ms)
          • Language code mode: Audio PID language descriptor can be parsed from the source ("Pass-through") or set manually.
        • Passed Through PIDs: (TS and HLS output modes only) Select input PIDs to transfer to the output stream, with no change except timestamps realigned to the output timestamps. Can be Audio, DVB-Teletext, DVB-Subtitle, SCTE35 and KLV PIDs.
        • Subtitles to convert:
          • Teletext by page: Select DVB-Teletext subtitles input stream by PID and page number. Teletext national character subset can be parsed from the source ("Pass-through") or set manually.
          • DVB-Subtitle by PID: Select DVB-Subtitle input stream by PID number.
          • Closed Caption channel: (EIA-608 only) Select Closed Caption input stream by channel ID.
        • SCTE-35 PIDs To Convert: Select input SCTE-35 PID to process.

      • Stream selection mode

        The transcoder automatically selects the PIDs from the service having the lowest service number.

        • Audio PID to convert: Select input audio PID(s) having the lowest PID number.
          • Delay: Audio delay control (-125ms to 125ms)
          • Language code mode: Audio PID language descriptor can be parsed from the source ("Pass-through") or set manually.
        • Passed Through Contents: (TS and HLS output modes only) All input PIDs of the selected type are transfered to the output stream, with no change except timestamps realigned to the output timestamps. Can be Audio, DVB-Teletext, DVB-Subtitle and SCTE-35 PIDs.
        • Subtitles to convert:
          • DVB-Subtitle by language: Select DVB-Subtitle input stream by language code and type (hearing impaired).
