TTX - Teletext and Subtitle

Although the technological beginnings of teletext date back more than 30 years, the system is still relevant today, as it is provided by most TV stations and used daily by many viewers.

Teletext is usually used for the transmission of additional information (e.g. for TV programme overviews, news, sports results, advertising or subtitles) and thus offers viewers added value.

Our teletext solution is available in two versions, either as a separate “standalone” system or as a module integrated in ourDiSA broadcast automation solution. Both variants offer TV broadcasters and service providers the possibility of automatically processing teletext data and inserting it into a video signal. The system also supports teletext subtitles.

  • Fully automated update of the teletext carousel
  • Unlimited number of pages and subpages
  • Data import from XML and database sources
  • Prioritization of pages (shorter access times)
  • Individual roll times of subpages
  • Data import from XML and database sources

Teletext and Subtitle

TTX can create a teletext carousel from various teletext file formats and insert this data into an HD-SDI or DVB (MPEG-TS) video signal.

The required teletext files (e.g. in TTP format) can be created with common software (e.g. FAB Teletext Editor). These can then be stored in a network watchfolder monitored by TTX and automatically imported into TTX using layout templates.

Changes to the data automatically lead to an update of the teletext carousel. The software is connected to the database containing the rundown and automatically updates the corresponding teletext pages, including a detailed program description (e.g. teletext page 300, 333, etc.). In addition, XML and RSS data can be imported, which e.g. makes it possible to automatically integrate current news or weather information into teletext pages.

TTX can process both file-based and live subtitles. Supported subtitle file formats include STL, SRT and WebVTT. Live subtitles are processed using the standard protocol Newfor.

  • Insert date and time with freely selectable colors within the header line
  • Selectable VBI lines
  • Supported subtitle file formats: STL, SRT, WebVTT
  • WSS signaling (Wide screen signaling) (DVB only)
  • VPS signaling (Video Programming System) (SD-SDI and DVB only)
