Abstract

A client in a home entertainment network can communicate with other components, including the server, over both a wired and a wireless link, with the particular path being selected based a component preference, and/or a bandwidth capability, and/or an occupancy ratio. Both links may be simultaneously used.

Claims

1. A home entertainment system, comprising:

at least one server configured for both wired and wireless communication; and

at least one component communicating with the server, a wireless path between the server and component being available for communication between the server and the component, a wired path between the server and component being available for communication between the server and the component, the server and/or the component determining which path from among the wired path and the wireless path to use for communication based on at least one of;

a bandwidth capability, an occupancy ratio.

2. The system of claim 1, wherein a respective address is associated with each path over which the component communicates.

3. The system of claim 2, wherein the addresses are IP addresses.

4. The system of claim 1, wherein the component is selected from the group of components consisting of:

televisions, and portable computers.

5. The system of claim 4, wherein the component is a TV.

6. The system of claim 1, wherein at least one of:

the server, and component, determines which path to use for communication based at least in part on a component preference.

7. The system of claim 1, wherein at least one of:

the server, and component, determines which path to use for communication based at least in part on a bandwidth capability.

8. The system of claim 1, wherein at least one of:

the server, and component, determines which path to use for communication based at least in part on an occupancy ratio.

9. A method for communicating a home network, comprising:

determining that both a wired path and a wireless path exist between two components;

responsive to a determination that at least one of the two components prefers a particular path, communicating data over that path;

determining that at least one of the two components does not prefer a particular path selected from the wired path and the wireless path; and

responsive to determining that at least one of the two components does not prefer a particular path selected from the wired path and the wireless path, communicating data between the two components over at least one of the paths between the two components based on at least one of;

a bandwidth capability, an occupancy ratio.

10. The method of claim 9, comprising communicating simultaneously between the components using both paths.

11. The method of claim 9, wherein a respective address is associated with each path over which the component communicates.

12. The method of claim 11, wherein the addresses are IP addresses.

13. The method of claim 9, wherein at least one component is selected from the group of components consisting of:

televisions, and portable computers.

14. The method of claim 13, wherein the component is a TV.

15. The method of claim 9, wherein at least one of a server, and a component, determines which path to use for communication based at least in part on a component preference.

16. The method of claim 9, wherein at least one of a server, and a component, determines which path to use for communication based at least in part on a bandwidth capability.

17. The method of claim 9, wherein at least one of:

a server, and a component, determines which path to use for communication based at least in part on an occupancy ratio.

18. A system for communicating between at least first and second components in a home network, comprising:

a first processor in the first component and a second processor in the second component, the first processor causing the first component to communicate data over a component-preferred path when a component-preferred path is indicated, the component-preferred path being selected from a wired and wireless communication paths over both of which the components communicate with each other;

the first processor, when no component-preferred path is indicated, communicating data to the second processor over at least one of the paths based on at least one of;

a bandwidth capability, an occupancy ratio.

19. The system of claim 18, wherein a respective address is associated with each path.

20. The system of claim 19, wherein the addresses are IP addresses.

21. The system of claim 18, wherein at least one component is selected from the group of components consisting of:

televisions, and portable computers.

22. The system of claim 21, wherein the component is a TV.

23. The system of claim 18, wherein at least one of:

a server, a component, determines which path to use for communication based at least in part on a component preference.

24. The system of claim 18, wherein at least one of:

a server, a component, determines which path to use for communication based at least in part on a bandwidth capability.

25. The system of claim 18, wherein at least one of:

a server, a component, determines which path to use for communication based at least in part on an occupancy ratio.
