Configuring the input

Prisma TS Splicer is designed to support live MPEG2-TS ingest multicast. Additionally, it integrates RIST support to receive TS multicast streams sent over the internet. To configure the service input, select the Input tab in the user interface.

Live multicast MPEG2-TS ingest

  • type: Select MPEG-TS/UDP
  • input redundancy: When two multicast input sources (primary and secondary) are accessible, choose between two modes. In the active/passive mode, the secondary source remains idle, not joining the multicast address or receiving UDP packets. The active/active mode lets both sources are captured simultaneously, offering statistics on transport and demux layers.
  • input loss timeout: Set to 1000ms by defaut, this is the time taken to switch between two sources if signal loss occurs.
  • Switch on ES data loss: Initiate a switch to the backup source in case of audio or video loss.
  • Delay: Only applicable if "Switch on ES data loss" is enabled. If audio or video is lost, it specifies the time to wait before switching to the backup source.

In the Primary section of the UI, configure the live multicast MPEG2-TS details:

  • Network interface: Designate the network interface capturing the input stream.
  • Stream address: Define the input stream's unicast or multicast IPv4 address.
  • Port: Input the port for capturing the stream.
  • IGMPv3 source filtering: Enumerate allowed IP addresses for IGMPv3, separated by commas.
  • Input synchronization mode: Depending on the input stream data, synchronize input via PMT program ID or stream PIDs.
  • Program ID: Select the appropriate program from the MTPS input stream.
  • PCR PID: Input the packet identifier for the Program Clock Reference, essential for synchronizing audio and video packets. If unspecified, it defaults to the output Video PID.

To configure a secondary input, click the +Add button under the Primary section. This action mirrors your primary settings in a new secondary section.

Select Input streams for Primary (and Secondary, if configured)

  • In the Video ID section, set the Video PID. If the input synchronization mode is set to PMT, video PID will be set to auto. Otherwise, specify the video PID to filter.
  • In the Audio ID section, add audio tracks by either PID or language.
  • In the Subtitle ID section, configure which subtitle tracks you wish to pass through to the output. You can select from the following subtitle types: Teletext, SCTE-27, DVB-Subtitles, ARIB B24. Set up filtering based either on PID or language.
  • Under Metadata ID: section covers passthrough for non-audio or video data, such as SCTE-35 signals, cuetones, AIT, EBIF, EISS, and PES metadata.
