Teletext Decoder

Teletext is a cost-free TV-centric information service and has become a very important feature for CE devices on the European and Asian market. For many years, TARA Systems has developed applications and tools for VBI data broadcasting and has supported and adviced many CE manufacturers regarding Teletext integration.

TARA Systems offers a Teletext software decoder providing high performance at low resource needs. It was developed as a reference decoder for the European market and supports the full level 1.5 and 2.5 specification. Because of TARA Systems' long-term experience with Teletext, the software works with all European TTX standards.

Teletext information service launched 35 years ago and TARA Systems was there almost right from the start. Read more here.

DiVi Teletext Generator for Test Purpose

After having integrated the Teletext Decoder into their own DVB software applications, developers need to verify their products, to guarantee high quality and stability. For that purpose, we offer our DiVi Software Tools - specifically the DiVi Teletext Generator. TARA also uses the DiVi Software Tools as part of our sophisticated automated test scenarios during the development of the Teletext Decoder and other DVB software.

To test Teletext Decoder integrations in analogue TV applications, TARA offers the well-known Geditor and VBI-Recorder.

Teletext L2.5 Broadcasters

Teletext Level 2.5 is currently broadcast in Germany (by 3Sat, ZDF, BR, BR alpha, SWR and PHOENIX), in the Netherlands (NED1, NED2 and NED3) and in France (France 3).

Services & Consulting

Based on our long-term experiences in VBI and DVB data broadcasting, we offer porting and integration of our Teletext Decoder to several hardware platforms as well as support and consulting for Teletext integration.

We also offer cost-effective test tools for data broadcasting, e.g. the DiVi Tools for DVB (digital) and the Geditor and VBI-Recorder for VBI (analogue). TARA 's tools enable developers to create, modify, and play out custom test data in order to verify their decoder software in factories, laboratories, and field tests.

The Teletext decoder was developed as a level 1.5 and 2.5 reference decoder and can furthermore be used by CE manufacturers to check and certify their own Teletext implementations.
