A video decoder (14). The decoder comprises an interface (30) for
receiving a set of an integer number S of analog input signals at a same
time. The decoder also comprises circuitry for processing the S analog
input signals, and that circuitry comprises an integer number N of
analog-to-digital converters (38.sub.x) for producing a set of the
integer number S of digital signals. Each digital signal in the set of S
of digital signals corresponds to a respective different one of the S
analog input signal, and N is less than S. The decoder also comprises
output circuitry (40.sub.x, 42.sub.x), coupled to the circuitry for
processing, for providing each digital signal in the set of S of digital
signals to a different respective output conductor.
