Abstract

A personal computer connected to the Internet can receive and store audio and audiovisual data or programming from the Internet. This audio and audiovisual programming can be provided by the computer over a digital connection to speakers and/or a monitor located away from the computer at a location convenient for a user. A remote control unit allows the user to send signals back over the digital connection to the computer to control the computer to provide the audio or audiovisual programming that the user desires over the digital connection to the speakers and/or monitor located where the user is. The computer may send a listing of the available programming to the remote control unit from which the user can make selections.

Claims

1. A system for managing audio and audiovisual programming comprising:

an audio server for outputing an audio signal;

at least one speaker; and

a digital connection between said at least one speaker and said audio server over which said audio server provides said audio signal in digital form to said at least one speaker.

2. The system of claim 1, wherein said audio server is a computer on which audio or audiovisual data is stored or which is receiving a stream of audio or audiovisual data.

4. The system of claim 1, further comprising a transceiver disposed with said speaker for communicating with a remote control unit, wherein said remote control unit controls output of said audio signal from said audio server to said at least one speaker, said remote control unit communicating with said audio server over said digital connection between said at least one speaker and said audio server.

5. The system of claim 4, wherein said audio server transmits a listing of available audio programming to said remote control unit via said connection and said transceiver.

6. The system of claim 5, wherein said remote control unit comprises:

a display device for displaying said listing; and

a user input device with which said user can select an audio program from said list and transmit a command for said audio server to output that selected audio program to said at least one speaker.

7. The system of claim 1, wherein said audio signal from said audio server is compressed and said at least one speaker further comprises decompression hardware for decompressing said signal.

9. The system of claim 1,

wherein said at least one speaker comprises a plurality of speakers, at least some of which have a transceiver for communicating with a remote control unit,

wherein a plurality of remote control units control said plurality of speakers such that a plurality of different audio signals are output by said audio server to respective speakers that are communicating with different remote control units.

10. The system of claim 1, wherein said at least one speaker is incorporated in a video monitor and said audio server is incorporated in an audiovisual server that outputs an audiovisual signal to said monitor, said audiovisual signal including said audio signal for said at least one speaker.

11. The system of claim 10, wherein said audiovisual server is a computer.

12. The system of claim 10, wherein said audiovisual server transmits a listing of available audiovisual programming to a remote control unit via said digital connection, wherein said remote control unit communicates wirelessly with a transceiver of said monitor.

13. The system of claim 12, wherein said remote control unit comprises.

a display device for displaying said listing;

and

a user input device with which said user can select an audiovisual program from said list and transmit a command for said audiovisual server to output that selected audiovisual program to said monitor.

15. The method of claim 14, wherein said transmitting is performed by an audio server which is a computer on which audio or audiovisual data is stored or which is receiving a stream of audio or audiovisual data.

16. The method of claim 15, wherein said computer is connected to the Internet and said method further comprises receiving said audio or audiovisual programming from the Internet.

17. The method of claim 14, further comprising controlling output of said audio signal from said audio server to said at least one speaker with a remote control unit that communicates wirelessly with a transceiver of said at least one speaker, wherein said remote control unit communicates with said audio server over said digital connection between said at least one speaker and said audio server.

18. The method of claim 17, further comprising transmitting a listing of available audio programming from said audio server to said remote control unit via said connection and said transceiver.

19. The method of claim 18, further comprising:

displaying said listing on a display device of said remote control unit;
