Control of data compressed recording and playback of multiple source video signals - has microcomputer controlled compression with sequential playback to expansion unit with error correction

摘要

A channel selector (100) allows a number of video signals to be transmitted to an analogue to digital converter (103) connected to a data compression and control unit (104). The input signal can be generated by a number of video cameras and/or recorders. The unit has a microcomputer (107) coupled to a synchronisation stage (102) providing control signals. Playback of the signals is provided by a unit that carries out data expansion combined with an error correction function. The unit is controlled by a microcomputer. USE/ADVANTAGE - Allows number of data compressed video images to be processed. .d18
