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

means for establishing a wired communication path between the components;

means for establishing a wireless communication path between the components;

means for communicating data over a component-preferred path when a component-preferred path is indicated, the component-preferred path being selected from the wired and wireless communication paths;

means for, when no component-preferred path is indicated, communicating data over at least one of the paths 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.

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

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

a server, a 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:

a server, a 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:

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