A video-on-demand system is described, which comprises a server and a user station. The video server is adapted to reproduce a selected television signal in various playback modi (normal, fast display, slow display, winding, rewinding, pause, etc.) in response to operating signals from the user station. Operating data which define the available operating signals (the user interface) are fixed in the server and are transmitted by the server to the station. The invention provides the possibility of downloading different versions of the user interface at different prices. For example, a television program with commercials may be offered with and without the facility of fast display. |
