Abstract
Abstract A video-on-demand system comprises a server station and a user station. The server is adapted to transmit a selected television signal with operating data defining a selected one of various available sets of playback modi (normal, fast forward, slow forward, rewind, pause, etc.) in response to operating signals from the user station indicating the selected set of playback modi. Operating data which define the various available operating signals (the user interface) are fixed in the server and are transmitted by the server to the user station. Downloading of different sets of the user interface at different prices is possible. For example, a television program with commercials may be offered at a higher price if it includes the facility of fast forward during commercials.
