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 networking module comprising:

a first block to receive a serial digital media signal, and to generate a parallel digital media signal based on the serial digital media signal; and

a second block to receive an incoming frame, and operative with the first block, to store the generated parallel digital media signal in a corresponding slot in the incoming frame to generate an outgoing frame, wherein the second block is to transmit the outgoing frame in response to receipt of another incoming frame, and wherein the outgoing frame includes network addressing information in addition to the generated parallel digital media signal.

2. The networking module of claim 1 wherein the incoming frame is one of a series of incoming frames, each frame being received at a predetermined interval, wherein the first block provides a new parallel digital media signal based on the serial digital media signal during the interval, and the second block sends a new outgoing frame with the new parallel digital media signal each time the incoming frame is received.

3. The networking module of claim 1 wherein the digital media signal is an audio signal.

4. The networking module of claim 1 wherein the digital media signal is a video signal.

5. The networking module of claim 1 wherein the first block comprises a first block input output interface and the second block comprises a second block input output interface, operatively coupled to the first block input output interface, to provide the parallel digital media signal to the first block.

6. The networking module of claim 5 wherein the first block input output interface is a general purpose input output interface.

7. The networking module of claim 5 wherein the first block input output interface is a peripheral control interface.

8. The networking module of claim 1 wherein the second block comprises an interface block to interface to a computer, to receive control signals to include in the outgoing frame.

9. The networking module of claim 8 wherein the interface block provides an i2c interface.

10. The networking module of claim 9 wherein the interface block provides a pci interface.

11. The networking module of claim 8 wherein the second block comprises a processor and memory, the memory to store a first procedure to store the parallel digital media signal in the outgoing frame and to send the outgoing frame, wherein the first procedure is downloaded from a computer.

12. The networking module of claim 1 wherein the first block is a field programmable gate array, and the second block is an application specific integrated circuit.

13. The networking module of claim 1 further comprising an analog to digital converter to provide the serial digital media signal to the first block based on an analog media signal.

14. The networking module of claim 1 wherein the second block is coupled to first and second ports, the incoming and the outgoing frames are received and sent, respectively, via the first port, wherein when the second block determines that the first port has failed, the second block receives subsequent incoming frames from the second port and sends subsequent outgoing frames to the second port.

15. A networking module comprising:

a first block to receive a serial digital media signal, and generate a parallel digital media signal based on the serial digital media signal; and

a second block, operative with the first block, to store the parallel digital media signal in a corresponding slot in an outgoing frame, and to send the outgoing frame in response to receiving an incoming frame;

wherein the second block is coupled to first and second ports, the incoming and the outgoing frames are received and sent, respectively, via the first port, wherein when the second block determines that the first port has failed, the second block receives subsequent incoming frames from the second port and sends subsequent outgoing frames to the second port.
