Patent ID: 7945706

Claim:
A signal receiving circuit applied to multiple digital video/audio transmission interface standards, comprising: at least an input interface, for receiving an input signal, the input interface comprising: a set of shared input terminals; a set of first separate input terminals, wherein when the input signal corresponds to a first transmission specification, the set of shared input terminals is used for receiving a first portion of the input signal corresponding to the first transmission specification and the set of first separate input terminals is used for receiving a second portion of the input signal corresponding to the first transmission specification; and a set of second separate input terminals, wherein when the input signal corresponds to a second transmission specification, the set of shared input terminals is used for receiving a first portion of the input signal corresponding to the second transmission specification and the set of second separate input terminals is used for receiving a second portion of the input signal corresponding to the second transmission specification; wherein the set of first separate input terminals are distinct from the set of second input terminals, wherein the first portion of the input signal corresponding to the first transmission specification is less than the entire input signal corresponding to the first transmission specification, and wherein the first portion of the input signal corresponding to the second transmission specification is less than the entire input signal corresponding to the second transmission specification; and at least an interface circuit, comprising: 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 input signals according to the control signal to generate an output signal.
