The following FAB solutions are available for DVB subtitles:
- Transmission as TS/IP or TS/ASI with FAB DVB Interface
- Insertion into TS files
1. Transmission as TS/IP or TS/ASI with FAB DVB Interface
DVB subtitles are transmitted in a separate PID by FAB DVB Interface. FAB Subtitler BCAST/XCD sends bitmap subtitles over network to FAB DVB Interface. Bitmap subtitles are converted to a DVB subtitle stream and transmitted in a separate PID. The PTS of the transmitted PID is synchronized to the PCR which is received from the DVB multiplexer.
2. 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.
