Abstract

A peripheral device is provided for a personal computer enabling the PC to provide the functions of a set-top box for television reception. Communication of television and control signals between the television and PC can be provided over the cable wiring already provided in the subscriber premises. Alternatively, wireless communication can be provided between the television and the PC. The invention obviates the need for a set-top box and the associated expense thereof. The television operations take place in the multitasking environment of the PC, so that the PC can be concurrently used for other applications.

Claims

1. A user interface for a cable television system, comprising:

means for inputting user requests for the selection of television program signals, wherein said television program signals are initially received at a personal computer (PC);

means responsive to said inputting means for converting said user requests into electrical signals;

first means for communicating said electrical signals to the PC, said PC having a first display associated therewith for displaying information received from the PC;

second means for receiving selected television program signals from said PC in response to said electrical signals; and

third means for communicating the received television signals to a television appliance having a second display associated therewith for displaying television images in accordance with said television signals.

2. An interface in accordance with claim 1 wherein:

said PC receives said television signals from a cable distribution system;

said first means are coupled to said cable distribution system for communicating said electrical signals to said PC; and

said television signals are communicated from said PC to said user interface via said cable distribution system.

3. An interface in accordance with claim 2 wherein:

said television signals are transmitted from said PC on a fixed television channel frequency; and

a notch filter is provided for blocking said television signals on said fixed television channel frequency from interfering with other signals on said cable distribution system.

4. An interface in accordance with claim 1 wherein said first and second means comprise a wireless communication path.

5. A television system for use with (i) a personal computer (PC) having a first display associated therewith for displaying information received from the PC, and (ii) a television appliance which is independent of said PC, said system comprising:

a television interface operatively associated with said PC, said television interface including a television tuner enabling the selection of television program services by said PC for output to said television appliance, wherein television program signals are initially received at said PC; and

a user interface adapted to be collocated with said television appliance and in communication with said PC, for enabling a user to remotely control said PC to select television program services to be displayed on a second display associated with said television appliance.

6. A television system in accordance with claim 5 wherein said user interface and PC communicate over a wireless link comprising:

a first transceiver operatively associated with said television interface for transmitting said television services to said television appliance and receiving control signals from said user interface; and

a second transceiver operatively associated with said television appliance and said user interface for receiving said television services from said television interface and transmitting said control signals to said television interface.

7. A television system in accordance with claim 5 wherein said television interface includes means for controlling a video recorder in response to instructions received from said user interface.

8. A television system in accordance with claim 5 wherein said PC provides computer resources for use by said television interface.

9. A television system in accordance with claim 8 wherein said computer resources are shared by said PC and said television interface, and include at least one of a hard drive, random access memory and a central processing unit.

10. A television system in accordance with claim 8 wherein said computer resources are used by said television interface to provide digital television services to said user.

11. A television system in accordance with claim 5 wherein said television interface provides compatibility among a plurality of consumer television appliances.

12. A user interface for a cable television system, comprising:

means for inputting user requests for the selection of television program signals, wherein said television program signals are initially received at a personal computer (PC);

means responsive to said inputting means for converting said user requests into electrical signals;

first means for communicating said electrical signals to the PC, said PC having a first display associated therewith for displaying information received from the PC;

second means for receiving selected television program signals from said PC in response to said electrical signals; and

third means for communicating the received television signals to a television appliance having a second display associated therewith for displaying television images in accordance with said television signals,

wherein television services provided on said television appliance and unrelated applications provided on said PC can be concurrently accessed.

13. A television system for use with (i) a personal computer (PC) having a first display associated therewith for displaying information received from the PC, and (ii) a television appliance which is independent of said PC, said system comprising:

a television interface operatively associated with said PC, said television interface including a television tuner enabling the selection of television program services by said PC for output to said television appliance, wherein said television program signals are initially received at said PC; and

a user interface adapted to be collocated with said television appliance and in communication with said PC, for enabling a user to remotely control said PC to select television program services to be displayed on a second display associated with said television appliance,
