Abstract:
1. An analog/digital signal processor for receiving input signals as analog signals or digital signals and outputting the input signals to a predetermined appliance through an analog communication unit or a digital communication unit, the processor comprising: a control unit determining whether the input signals are digital signals or analog signals to generate a determination result and controlling a processing path and an output path of the input signals in accordance with the determination result; a switching unit switching the input signals to the analog communication unit or the digital communication unit under a control of the control unit; and an encoding unit encoding the input signals to generate encoded input signals and a decoding unit decoding the encoded input signals encoded by the encoding unit or the input signals, wherein, according to user selection, the switching unit outputs the input signals that are analog signals to one of the analog communication unit without encoding the input signals and the encoding unit.
