In the Multi-viewer Inspector’s “Connections” tab, the icons used to show the Channel status have been changed from the Red (🔴)/Yellow (🟡 )/Green (🟢 ) indicators to icons to display the channel status in a clearer and more understandable way.

  • SRT and UDP streams support the SMPTE 2038 specifications related to the transport of VANC data (e.g. CEA-708, OP-47, SCTE-104) for both the output and the live input.

  • SRT and UDP streams support ATSC A/53 closed captions in the MPEG transport stream for both the output and the live input. When using a live input, the ATSC A/53 closed captions are disabled if the stream contains SMPTE 2038 information.

  • SRT and UDP streams support SCTE-35 events in the MPEG transport stream for both the output and the live input. When using a live input, SCTE-35 is disabled if the stream contains SMPTE 2038 information. Any SCTE-104 events scheduled using the “Event” option will be automatically converted to SCTE-35.

  • Adjustable encoding parameters. The H.264 profile/bitrate as well as the AAC audio bitrate can be defined when using SRT or UDP streaming out.
