Recent regulatory agreements open up a range of the frequency spectrum sufficient to support close to two hundred TV channels and a wide range of radio stations using the Digital Video Broadcast (DVB) and the Digital Audio Broadcast (DAB) standards. Users will be able receive broadcast content via TV-sets as well as interactive terminals, such as desk-top computers, laptops, personal digital assistants, mobile phones, etc. Terminals can be equipped with DAB and/or DVB receivers. Most of them can be used to provide return channels via WLAN/Internet, fixed telephone lines or GSM/GPRS/3G. Interactivity, new to media distribution, can be integrated with the media content. Some of the technology is already available; A DVB transmitter can be integrated in the existing test bed environment. Some content, including interactive services, can be made operational immediately.

Several areas relating to equipment need a longer study. Introduction of new technology can take a long time due to a number of reasons. Lack of appropriate equipment at the right time is one such key factor. Hence, the centre will address research on low cost solutions for mass market needs, including hardware for mobile phones, TV-sets, home networks etc, as well as systems that can handle a large number of users. Contrary to the case in the telecom sector, the content represents the value in the broadcast sector. This fact affects business models as well as system solutions. Content providers are not quite prepared for interactive media and user benefits are unclear, although some experience has been gained from the cable industry. The centre will integrate research on interactive media that can be used in public administration considering the intellectual property rights of media industry, networking aspects and terminal hardware.
