System and method for transmitting audio data over serial link

摘要

System and method for transmitting video and audio data words via a serial data link. A transmitting device includes a first module for generating an audio data frame comprising an audio data word and a frame separation code; and a second module for generating high speed data frames each comprising at least a portion of a video data word and only a portion of the audio data frame, and for transmitting the high speed data frames via the serial data link. A receiving device includes a first module for forming the video data word from one or more high speed data frames, and a second module for forming the audio data frame from portions of high speed data frames. The second module may extract the audio data word from the audio data frame, and generate an audio clock based on a rate in which audio data words are received.

主权项

1. A transmitting device for transmitting high speed and low speed data words via a serial data link, comprising:
a first module configured to generate a low speed data frame, the low speed data frame further comprising a frame separation code, a frame start code, a frame data comprising a low speed data word with separation code collision protection encoding, and a frame end code, wherein the frame data with separation code collision protection encoding prevents the frame separation code from appearing in the frame data; and a second module configured to: generate a high speed data frame comprising at least a portion of high speed data word and a portion of the low speed data frame; and serially transmit the high speed data frame via the serial data link, wherein the transmitting device comprises one or more processors and one or more memories.
