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.

Abstract: A method and apparatus provide for the elimination of any net DC component from the transmission of binary data sequentially in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., 0's are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., 1's, are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.
