Abstract
The invention provides a signal receiving circuit applied to multiple digital video/audio transmission interface standards. The signal receiving circuit includes at least an input interface for receiving an input signal, and at least an interface circuit. The input interface includes a set of shared input terminals, a set of first separate input terminals for receiving an input signal corresponding to a first transmission specification with the set of shared input terminals, and a set of second separate input terminals for receiving an input signal corresponding to a second transmission specification with the set of shared input terminals. The interface circuit includes a control circuit coupled to the input interface for supplying a control signal, and a processing module coupled to the input interface and the control circuit for processing the input signal according to the control signal to generate an output signal.
