Implementation method of high-definition audio input and power amplifier equipment

The invention relates to an implementation method of high-definition audio input and power amplifier equipment. The implementation method of the high-definition audio input comprises the following steps of: reading EDID (Extended Display Identification Data) information of receiving equipment; analyzing the EDID information, and judging whether the receiving equipment is digital audio interface equipment, if so, modifying a first data block in the EDID information, and adding a data block for storing audio format information supported by the power amplifier equipment, if not, analyzing the audio format information (supported by the receiving device) of a second data block in the EDID information, and modifying the audio format information (supported by the receiving equipment) in the second data block into the audio format information supported by the power amplifier equipment; and transmitting the modified EDID information to input source equipment. According to the implementation method of the high-definiti
