METHOD AND APPARATUS FOR SENDING AND RECEIVING AUDIO DATA

摘要

A method and an apparatus for sending and receiving audio data, so as to solve the problem that in the prior art, a simulating audio and video transmission system is complex in cable connection structure. The audio data is overlaid at a preset position of a video blanking interval of video data, sending and receiving of audio signals are carried out, and co-cable transmission of the audio and video data can be achieved.

1. A method for transmitting audio data, the method comprising:
sampling and quantizing an analog audio signal and determining audio sampling values corresponding to the audio data to be transmitted; buffering the audio sampling values into a buffer area in a First Input First Output, FIFO, method; after a color synchronization signal of an analog video signal is detected, superimposing the audio sampling values buffered in the buffer area in video blanking intervals of the analog video signal, to obtain the analog video signal comprising an audio carrier sampled signal; and transmitting the analog video signal comprising the audio carrier sampled signal to a receiver.
