Abstract

A user terminal exchanges information with a server through a transmission medium. A coupling unit couples the user terminal to the transmission medium in accordance with information from the server. Likewise, the server is controlled in accordance with information from the user terminal. In this manner, communication is created and performed between the server and the user terminal. The user terminal may be a Set-Top Unit which may be adjusted to the transmission medium by, for example, a physical medium converter or the communication itself between the Set-Top Unit and the server may be adjusted as directed by programs installed in the Set-Top Unit which may originate from the server.

Claims

1. A system for communication, comprising:

at least one network medium for transmitting network data signals;

one or more user apparatus for receiving the network data signals from the network medium; and

control means for controlling said one or more user apparatus;

wherein said control means transmits performance capability information of said control means as data signals over the network medium, and wherein said one or more user apparatus is controlled by said control means based upon information for controlling received by said control means over said network medium, and generated in response to said transmitted performance capability information.

2. The system according to claim 1, wherein the control means comprise a separate Set-Top Unit (STU).

3. The system according to claim 1, wherein the control means are incorporated into the one or more user apparatus.

4. The system according to claim 1, wherein the one or more user apparatus is a television set.

5. The system according to claim 1, wherein programs for creating and performing communication stored in said control means comprise programs for controlling an adjustment unit for a user apparatus including a screen driver, a keyboard driver or an I/O port driver, reaction to calls, decoding, handling of remote control, handling of downloaded programs and/or a Resident User Interface (RUI).

6. The system according to claim 5, wherein said one or more user apparatus includes at least one of a screen driver, a keyboard driver, an I/O port driver, remote control means, means for processing downloaded programs and a resident user interface.

7. The system according to claim 1, wherein said control means includes a physical medium converter.

8. The system according to claim 7, including a connection channel, connected between the one or more user apparatus and the physical medium converter;

and wherein the physical medium converter comprises a first converter for converting signals to and from the connection channel, a second converter for converting signals to and from the network medium and a connection between the first converter and the second converter.

9. The system according to claim 1, where the control means comprises a micro operating system with a minimum size set of instruction to support, alone and/or in combination with static processes, different application programs, and programs downloaded to the user apparatus.

10. The system according to claim 1, where the control means comprises means to provide from the user apparatus, upon establishment of an initial contact with an additional apparatus connected to said network medium, an identification format;

and wherein a program best suited for the control means is determined and downloaded to the coupling means.

11. A unit suitable for a communication system, said communication system comprising:

at least one network medium for transmitting network data signals;

one or more user apparatus for receiving the network data signals from the network medium; and

control means for controlling said one or more user apparatus;

wherein said control means transmits performance capability information of said control means as data signals over the network medium, and wherein said one or more user apparatus is controlled by said control means based upon information for controlling received by said control means over said network medium, and generated in response to said transmitted performance capability information.

12. The unit according to claim 11, provided with an operating system of the real time, multitasking, object oriented type.

13. The unit according to claim 11, further comprising a physical medium converter for creating and performing communication with an additional apparatus connected to said network medium.

14. The unit according to claim 11, comprising a network interface (down and return channels);

RGB/PAL/SECAM/NTSC interfaces;

analog/digital audio interfaces;

an UHF interface and an interface for a MPEG-2 demultiplexer.

15. The unit according to claim 11, further comprising a micro operating system with a minimum size set of instruction to support, alone and/or in combination with static processes, different application programs, and programs downloaded to the user apparatus.

16. A unit according to claim 11, which comprises means to provide from the user apparatus, upon establishment of an initial contact with an additional apparatus connected to said network medium, an identification format so that a program best suited for the unit is received by the unit.

17. A method for communication from a user apparatus via a network medium, where information is transmitted and received via control means and through said network medium, comprising the steps of regulating transmission of information to and from said control means in accordance with dynamic processes, transmitting Performance capability information of said control means, downloading to said control means programs for dynamic processes in accordance with said performance capability of said control means, and storing said programs in memory means of said control means, said programs regulating a stream of data to and from the user apparatus.

18. The method according to claim 17, wherein said transmitted information comprises interactive digital video/audio data.

19. The method according to claim 17, wherein upon establishment of an initial contact with said additional apparatus, an identification format relating to the coupling means is provided from an user apparatus so that a program best suited for the coupling means is received by said coupling means.
