The flexible DiVi Software Tools enable developers to create their own DVB transport streams with customer specific data, e.g. Teletext data, ready to broadcast into the receiver product. TARA also uses the DiVi Software Tools as part of its 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 its well-known Geditor and VBI-Recorder.
