The following FAB solutions can be used for teletext subtitles:
- Transmission of teletext subtitles in SDI
- Transmission of teletext subtitles over TS/IP or TS/ASI
- Insertion into TS files
- Insertion into MXF files
1. Transmission of teletext subtitles in SDI
FAB Subtitler BCAST/XCD can transmit subtitles over network to FAB Teletext Subtitle Generator which generates a teletext stream with one or more teletext subtitle pages. The teletext stream can be inserted into one or more different SDI signals by FAB SDI PCIe card.
2. Transmission of teletext subtitles over TS/IP or TS/ASI
FAB Subtitler BCAST/XCD can transmit subtitles over network to FAB Teletext Subtitle Generator which generates a teletext stream with one or more teletext subtitle pages. The teletext stream can be transmitted as TS/IP or TS/ASI synchronized to a PCR by FAB DVB Interface.
3. Insertion into TS files
FAB Subtitler PRO/LIVE/MPEG can open subtitle files in many different formats and insert the subtitles from the subtitle file as DVB bitmaps into a TS file as a stream with a separate PID. Watchfolder operation is supported but FAB Subtitler MPEG is required to be able to control FAB Subtitler using a REST interface.
4. Insertion into MXF files
FAB Subtitler MPEG can open subtitle files in many different formats and insert teletext subtitles from the subtitle file as teletext subtitles into MXF files into VBI/VANC. Watchfolder operation and control of FAB Subtitler using a REST interface are available.
