Subtitling - Broadcast
FAB Subtitler DVB

FAB Subtitler DVB is used for convertion of teletext subtitles to DVB or open subtitles.

DVB subtitling is used in satellite and terrestrial DVB (Digital Video Broadcast) transmissions. Only Set Top Boxes (DVB decoders) that support DVB subtitles are capable of displaying DVB subtitles.

DVB subtitles are transmitted in a separate DVB stream with a separate PID. Every subtitle contains a PTS (presentation time stamp) which is defined by the subtitle transmission system. The PTS is calculated from the video stream which comes from the DVB ASI output of the DVB multiplexer and is connected to the input of FAB DVB Interface.

The DVB encoder/multiplexer must be configured so that the subtitle streams with correct PIDs are passed through and the PMT (Program Map Table) must be configured correctly so that Set Top Boxes will associate subtitle streams to video streams correctly.

FAB Subtitler can be used for transmission of DVB subtitles in two different modes:

Mode 1: Decoding of teletext subtitles and conversion to DVB subtitles with FAB Subtitler DVB

Mode 2: Transmission of subtitle files controlled by an automation system with FAB Subtitler BCAST

Both modes support simultaneous transmission of subtitles in multiple languages to one or more DVB multiplexers.
