Pilot operation for digital terrestrial television and interactive MHP applacations
The project

In this part of the project, special emphasis was placed on the additional digital interactive services broadcast along with !TV4GRAZ‘s programming content. For each show, an MHP portal in the broadcaster‘s individual design of-
fered numerous interactive functions. An electronic program guide (EPG) was developed as an independent MHP product and provided viewers with an overview of the content broadcast on the four channels at all times.

These MHP applications were conceived by the television broadcasters and mainly programmed in the development departments at BearingPoint, Siemens AG Österreich,
Sony NetServices and PLOT.
Through the MHP portals, the viewer could access current news, weather forecasts, additional information on the show currently on the air, as well as a variety of other information. The set-top boxes, which were equipped with modems or ADSL connections, also made it possible to test return channel-based functions. For example, viewers could easily vote on controversial topics discussed in shows or vote for their film request of the week using their remote controls. These functions could even be used to order merchandise. An application developed by Österreichische Sportwetten GmbH, tipp3 live!, also enabled the test households to bet on football matches. Current voting results and betting odds were broadcast to the viewers via the MHP portals.

Data transmitted via the return channels was handled by a data processing center set up at Siemens AG Österreich and then forwarded to the specific addressees (portal and application providers).

In this way, the cycle of interaction in digital television was completed for the first time in Austria.
