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.

Claims

1. A video-on-demand system comprising:

a video server for transmitting a selected television program signal together with operating data defining an operating signal for playback of the television signal in accordance with any of a plurality of available sets of playback modi; and

a user station for receiving and displaying the selected television program, said user station including an operating processor for generating and transmitting to the server an operating signal corresponding to a selected one of said sets of available playback modi;

characterized in that the operating data transmitted by the server defines available sets of playback modi of the television signal, and the operating processor in the user station is adapted to receive and store the operating data for a selected one of said sets of playback modi and to transmit an operating signal corresponding to said selected set to said server.

2. A video-on-demand system as claimed in claim 1, wherein the user station further comprises means for enabling the operating processor to charge an amount for receiving the selected television program, the charged amount being dependent on the selected set of playback modi.

3. A video-on-demand system as claimed in claim 1, wherein the server is adapted to modify the operating data associated with a selected television program during transmission of said program.

4. A video-on-demand server for transmitting a selected television signal to a user station, said server comprising means for re-transmitting the television signal in accordance with any of a plurality of available sets of playback modi defined by operating data;

and means for transmitting to the user station operating data defining the available sets of playback modi.

5. A video-on-demand server as claimed in claim 4, wherein the operating data transmitted by the server enables the user station to generate an operating signal corresponding to a selected one of said sets of playback modi.

6. A video-on-demand server as claimed in claim 5, further comprising means for enabling the user station to charge an amount for receiving a selected television program, the charged amount being dependent on the selected set of playback modi.

7. A video-on-demand server as claimed in claim 6, wherein the server is adapted to modify the operating data during transmission of the selected television program.

8. A user station for receiving and displaying a television program corresponding to a selected television signal transmitted by a video-on-demand server, said user station comprising an operating processor for generating and transmitting to the server an operating signal which defines a selected one of a plurality of available sets of playback modi;

characterized in that the operating processor is adapted to receive from the server operating data defining the available sets of playback modi, to store the operating data for a selected one of said sets of playback modi, and to generate and transmit to the server an operating signal defining the selected set of playback modi.

9. A user station as claimed in claim 8, further comprising means for charging an amount for receiving a selected television program, the charged amount being dependent on the selected set of playback modi.

10. A user station as claimed in claim 9, wherein the operating processor is adapted to receive modified operating data during transmission of a selected television program and to replace the already stored operating data with the modified data.

11. A method of transmitting a television signal representing a selected television program from a video server to a user station, the server being adapted to transmit the television signal in accordance with a selected one of a plurality of available sets of playback modi defined by operating signals, the user station being adapted to generate and transmit said operating signals to the server;

said method comprising the steps of;

transmitting from the server operating data defining the available sets of playback modi;

storing in the user station the operating data for a selected one of said sets; and

transmitting from the user station to the server an operating signal corresponding to the selected set of playback modi.

12. A method as claimed in claim 11, wherein the user station charges an amount for receiving a television program, the charged amount being dependent on the selected set of playback modi.

13. A method as claimed in claim 11, wherein the server modifies the operating data during transmission of the selected television program.
