Video decoder with different signal types processed by common analog-to-digital converter

摘要

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_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_x, 42_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.
