A method for transmitting an audio-video data can include: receiving a video signal from a video source and an audio signal from an audio source; receiving an audio data of the audio signal, and detecting an audio frame clock signal of the audio signal; converting the audio data to an audio data sequence with a first encoding rule; generating a start data code, an end data code, and an audio frame clock code according to the audio data sequence and the audio frame clock signal with a second encoding rule, where the first encoding rule is different than the second encoding rule; generating a low speed data frame according to the audio frame clock signal and the audio data sequence; inserting the start data code at the beginning of each audio data sequence, and inserting the end data code at the ending of each audio data sequence.
Description
technical field [0001] The invention relates to the technical field of audio and video data transmission, in particular to a transmission method and a transmission system for simultaneously transmitting audio and video data using only one serial line. Background technique [0002] The video and audio data of electronic products can bring users an excellent consumer experience, such as car multimedia navigation systems, megapixel camera systems, and car rear seat entertainment facilities. With the rapid development of electronic information technology, higher requirements are put forward for the transmission of video data and audio data. How to occupy less resources and quickly transmit audio and video data is the current development direction of audio and video data transmission. [0003] According to an implementation solution of the prior art, when video signals and audio signals are transmitted, two independent single serial lines need to be arranged, namely, a video coax...
