A signal processing apparatus for processing a packetized data stream and an apparatus for reproducing the same.

摘要

A system for generating a signal (SP) for coupling digital audio, video and data signals in compressed form via a bus (500). A processing means (98) formats the digital audio, video and data signals into superpackets (SP) for transmission via the bus (500). Each superpacket (SP) comprises a timestamp (TS), and a transport packet (TP), representative of the digital audio, video and data signals. The superpackets (SP) have a fixed duration and occur at variable intervals. Devices (50) receive the superpacket (SP) signal and may utilize the timestamps (TS) for clock synchronization. A recording and replay device (400) processes the variable superpacket signal occurrence for recording. Reproduced timestamps (401) are utilized to control restoration of the superpacket (SP) signal to have substantially the duration and occurrence as when formatted for bus (500) transmission. A simplified bus (501) couples superpackets (SP) between devices (100, 400). An indicia (Vs) is added to a superpacket (SP) signal to provide automatic control of device bus interfaces (102). The automated interface control is also responsive to device control status.
