FAB Teletext Generator

FAB Teletext Generator FT-DVBTSG / FT-DVBTDG is a software package for PC for generation of a teletext stream with teletext subtitles and teletext pages. The teletext specification defines that teletext data has to be present in every field of the TV picture even when no subtitles are transmitted. FT-DVBTSG / FT-DVBTDG runs as a Windows Service and generates a teletext stream for every TV field which is inserted into SDI or transmitted as TS over ASI or IP.

The following features are included:

  • Generation of a teletext stream with up to 8 teletext subtitle pages.
  • FT-DVBTDG can transmit all teletext page numbers from 100 to 8FF each with a maximum of 255 subpages.
  • FT-DVBTSG is limited to transmission of up to 100 teletext page numbers each with a maximum of 255 subpages.
  • For insertion of the teletext data into VBI/VANC of SD/HD/3G-a SDI signal the FAB PCIe Card is required. The same teletext stream can be inserted into multiple SD/HD-SDI signals when multiple FAB PCIe Cards are installed in the same computer.
  • For transmission of the teletext stream over ASI or IP to a DVB multiplexer the software license FAB DVB Interface FT-DVB is required. The same teletext stream can be transmitted to multiple DVB multiplexers when multiple FT-DVB licenses are installed on the same computer.
  • Multiple teletext streams with different content can be generated on one PC by installing multiple FT-DVBTSG licenses on the same PC.
