Abstract
A separator circuit receives a stream of data including both audio and video components. The separator circuit separates the audio and video components for transmission to appropriate devices. In the preferred embodiment, the separator circuit is part of a decompression engine which decompresses the received stream of data and also separates the audio and video components. Preferably, the decompression engine is implemented within a device configured for coupling to an IEEE 1394-1995 serial bus network. Alternatively, the decompression engine is implemented as a separate dedicated device within the IEEE 1394-1995 serial bus network. After separating the audio and video components, one or both of those components are transmitted from the decompression engine over one or more isochronous channels on the IEEE 1394-1995 serial bus, to the appropriate devices. When the decompression engine is implemented within a device, an appropriate one of the audio or video components is sent to circuits within the device while the other component is transmitted over the IEEE 1394-1995 serial bus.
