ABSTRACT:
A time base corrector is comprised of a plurality of system function modules implementing the functions for time base correcting an analog composite color video signal with a stable reference video signal. The system function modules obtain control data and communicate status data to a system control through a plurality of module function registers located in each module. The module function registers are connected to and selectable by a system bus of a microprocessor. The microprocessor has the module function registers mapped as addresses in its memory space to provide an architecture for communication and control of each function module by the system control.
