Abstract

The invention provides a receiving circuit of a high image quality multimedia interface and a method of determining a transmission mode of the high image quality multimedia interface. The receiving circuit of the high image quality multimedia interface is used to receive an image signal and an input clock rate transmitted via the high image quality multimedia interface and generate output data. The receiving circuit of the high image quality multimedia interface comprises a sampling circuit, a data comparison circuit and a control circuit, wherein the sampling circuit is used to sample the image signal according to a transmission mode and an input clock rate so as to generate the output data; the data comparison circuit is coupled to the sampling circuit and is used to determine whether the output data includes preset data so as to generate a determination result; and the control circuit is coupled to the sampling circuit and the data comparison circuit and determines a transmission mode according to the determination result.

Description

technical field [0001] The present invention relates to a high-definition multimedia interface (High-Definition Multimedia Interface, HDMI), in particular to a circuit and a method for automatically judging the signal transmission mode of the high-definition multimedia interface. Background technique [0002] There are many versions of the high-definition multimedia interface, among which version 1.4 and version 2.0 are the mainstream. The data transmitted by the high-definition multimedia interface includes at least a clock signal and an image signal. For version 1.4, the frequency of the image signal is 10 times that of the clock signal and the frequency range of the clock signal is 25MHz ~ 340MHz; for version 2.0, it is 40 times that of the clock signal and the frequency range of the clock signal is 85MHz~150MHz. That is to say, the receiving end of the high-definition multimedia interface must perform corresponding processing according to the current signal transmissio...
