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.
