FAB Subtitler BCAST is a software package for a PC with Windows which is used for automatic transmission of subtitles in multiple languages.

Subtitles can be transmitted as:

  • Open (in-vision) subtitles keyed over image.
  • Teletext subtitles inserted into SDI or transmitted as SDI/IP or TS/IP or TS/ASI.
  • DVB subtitles transmitted as TS/IP or TS/ASI.
  • CEA-608/708 Closed Captions inserted into SDI.
  • Subtitles for HLS/DASH live streaming independent of live streaming encoder.
  • Many outgoing network protocols are supported for transmission of subtitles (i.e. EBU-TT Live, ESUB-XF, NEWFOR, FAB, …).

Subtitles can be transmitted from different sources:

  • Subtitles from subtitle files with timecode. Files necessary for transmission of subtitles will be downloaded from a file server or FAB Subtitle Database and deleted when not required anymore.
  • Subtitles received over network from live subtitling workstations. Many network protocols (NEWFOR, FAB, ESUB-XF, …) are supported for reception of subtitles.
  • Subtitles received over SDI video as teletext subtitles can be retransmitted as teletext subtitles or converted to another format.
  • Subtitles received from live transcription service where audio from SDI or IP input is sent to the transcription service and received text is transmitted as subtitles to enable 100% automatic subtitling.


Transmission is triggered by an ID and starting timecode or by a special command received from the playout/automation system. Many different playout/automation systems incl. Imagine, Pebble Beach, Aveco, Etere, are supported …

Master/Hot-Standby operation with automatic switchover in case of failure is supported.

FAB Subtitler XCD is a software package for PC which includes the same functionality as FAB Subtitler BCAST with the following limitations:

  • Transmission of subtitles is only possible from one of the following sources: subtitle file or SDI video or network. To use a different source the software has to be reconfigured.
  • The subtitle editor is not included

For a detailed comparison of functionality please read the Product comparison page.

The software works in the following way

  • Subtitle files for transmission have to be stored on the local hard disk or on a file server.
  • The filename of the subtitle file corresponds to the ID of the playlist item in automation system.
  • The automation system sends the ID when it starts transmitting a new playlist item.
  • FAB Subtitler BCAST/XCD will search for the subtitle filename ID.stl
  • If the subtitle file is found FAB Subtitler BCAST will open it and start transmitting it.
  • Subtitles are synchronized to timecode which is received from automation system.

For other functionalities, i.e. live transcription, reception of teletext subtitles from SDI special commands are available which activate/deactivate the necessary operation mode.
