Abstract

In one embodiment of a networking module, a first block receives a serial digital media signal, and provides a parallel digital media signal based on the serial digital media signal. A second block, operative with the first block, stores the parallel digital media signal in a corresponding slot in an outgoing frame, and sends the outgoing frame in response to receiving an incoming frame.

Claims

1. A multi media system comprising:

a plurality of networking modules, coupled to each other, at least a subset of the networking modules receiving control information in frames, wherein at least one of the networking modules includes a media access controller (MAC), a first physical layer interface (PHY), and a second PHY, wherein the MAC is coupled to the first PHY and the second PHY, and wherein the first PHY is associated with a first link between the at least one networking module and another one of the networking modules, and the second PHY is associated with a second link between the at least one networking module and the another networking module; and

a computer coupled to the at least one networking module, the computer comprising a networking module application program to control the networking modules by supplying the control information to the at least one networking module.

2. The multi media system of claim 1 wherein the control information comprises information to assign audio channels.

3. The multi media system of claim 1 wherein the at least one networking module receives monitoring information from at least one other networking module, and provides the monitoring information to the networking module application program.

4. The multi media system of claim 1 wherein the networking module application program receives digital audio signals from the networking modules, mixes the audio signals, and transmits the mixed audio signals to the at least one networking module.

5. The multi media system of claim 1, wherein the MAC is configured to transmit frames from the at least one networking module to the another networking module via the first PHY and the first link, and

wherein, in response to a detection by the MAC that the first link has failed, the MAC is configured to switch the transmission of the frames to the another networking module via the second PHY and the second link.
