Abstract
A method for transmitting audio data of a plurality of audio sources through a single SPDIF link, includes: sequencing and multiplexing the audio data of the plurality of audio sources to pack the audio data of the plurality of audio sources into a plurality of frames of a block; performing bi-phase mark encoding on the audio data in the frames; appending preambles Z, X, and Y of the AES3/SPDIF stream format to the frames according to the number of audio sources in a first mode, or appending preambles Z, X, and Y of the AES3/SPDIF stream format and a specific preamble differing from preambles Z, X, and Y to the frames according to the number of audio sources in a second mode; and outputting the frames carrying the audio data into the SPDIF link with a frame rate greater than an audio sampling frequency of one of the audio sources.
