The invention relates to an infinite cascade long-distance audio and video transmission method and an extension system, and belongs to the field of HDMI audio and video transmission. The transmission of audio and video data is completed through a receiving stage, at least one intermediate stage and a transmitting stage, and the transmission method comprises the steps: enabling the receiving stage to receive a source signal and encodes the source signal; performing amplification processing on the encoded source signal to obtain a primary amplification signal and outputting the primary amplification signal; enabling the intermediate stage to receive the primary amplification signal and perform multi-stage amplification to obtain a multi-stage amplification signal and output the multi-stage amplification signal; enabling the transmitting stage to receive the multi-stage amplification signal and decode and restore the multi-stage amplification signal; and amplifying the decoded and restored multi-stage amplificat
