Siemens Interactive Application Center (IAC)

The hub for interactive television

IAC acted as the hub in the project‘s interactive cycle, for example by transporting data to television stations in order to allow voting results to be displayed on screen in the viewers‘ homes. Using the return channel, viewers with an MHP-compatible set-top box can use the full interactive functions offered by various portals. In the first interactive advertising portal in Austria, Siemens developed an advertising application for its SX1 mobile telephone (p. 62). In order to enable merchandise orders and individualized votes or bets, it was necessary to identify individual viewers in this process. For this purpose, the corresponding applications required ITV viewers to enter their user ID number and password when using such services. The data transmitted from the households to the Siemens Interactive Application Center were encrypted for data protection purposes.
