Summary: 
When a new digital broadcasting system is introduced for the viewers, it is important to be able to include new services and system aspects. That is to give the viewers new experiences and meet the demands they might have in the future. To fulfil the viewers expectations, is a key for success for the introduction of new service and product. It is equally important to look at the long term perspective and have the possibility to gradually develop the digital broadcasting systems we establish today. A fully integrated multimedia system is a hybrid of different media services, distribution paths and display object. The pros and cons of each of them must be examined and each of them used where best suited. This will probably give a more complex media world with fuzzy borders between what is broadcasting, packaged media and what is the on-line information society. In order to balance this, any new digital multimedia system needs to be developed with an open architecture, based on generally agreed standards and possibly follow a non-proprietary approach. IDUN, a prototype system for multimedia broadcasting, is on its way to fulfil these requirements. IDUN combines the powerful point to multi-point emission, domestic data storage and computer processing with the telecommunication network. It is feasible to introduce it in the analogue world of today but could better be utilised in a fully digital future. Some possible services are further proposed. Some of them with a tight relation to what a broadcaster already produces, which could give an evolutionary transfer to the new digital world.
