StreamXpert Adds Teletext Analysis

Teletext is the latest addition to the wide range of elements already presented by DekTec's Transport Stream analyzer, the StreamXpert®. Teletext has been around for decades and has survived the digitalization of television services. Most television sets support it and most set-top boxes used today include the functionality of retrieving teletext data from the stream and presenting it on the TV set as part of a selected broadcast channel.

StreamXpert decodes DVB Teletext (EN 300 472) information and builds the pages as they would appear on a TV screen. An engineer or operator can browse through the pages and verify that the pages decode as expected. The Teletext decoder supports up to level 2.5 Teletext and a subset of level 3.5 extensions.

The pages are visualized in StreamXpert as part of the Transport-Stream tree. All Teletext content is stored in an internal database. The user can zoom in to page or sub-page level and obtain information such as duration time and refresh interval.
