In the future, quiz show contestants will be able to use a UMTS cell phone to participate in game shows from any location. Siemens and Grundy Light Entertainment have thus created a completely new possibility for actively participating in TV shows. A successful test has demonstrated how viewers can become part of a live TV show by means of a video link. The live video transmissions in the tests were conducted either via UMTS mobile radio technology or through the fixed-line network with the help of the Surpass Home Entertainment system from Siemens.
