Abstract: A method of synchronization for a network and a system is provided, wherein a first device is utilized to decode an audio signal and a second device is utilized to decode a video signal. The method of synchronization includes determining an output difference. In one embodiment, the output difference is calculated by determining a first processing speed of a first decoder in the first device and determining a second processing speed of a second decoder in the second device. In another embodiment, the method of synchronization further includes utilizing the difference between the first processing speed and the second processing speed to synchronize the audio signal with the video signal. In a further embodiment, a decoded audio signal is stored in a first buffer in the first device. In yet another embodiment, the method of synchronization further includes utilizing the difference between the first processing speed, the second processing speed and a distance between the first device and the second device to synchronize an output of the audio signal stored in the first buffer with the video signal.

Abstract: An audio/video (AV) network, system, and method is provided which prevents audio blackout in an AV home system. The AV network includes a first device configured to decode an audio signal which comes on the transport stream with a standard definition signal as well as a high definition signal, while a high definition video signal is passed through a digital connection, for example an i.LINKnull, to a second device for decoding. In one embodiment, the first device is a set top box and the second device is a high definition television. In another embodiment, the first device and the second device form an audio/video network through the digital connection. In a further embodiment, the AV network forms a part of the home AV system.
