Claim Text:
1. A device configured for transmitting a plurality of audio channels as a time division multiplexed audio stream, said device comprising: (a) an analog audio input path, the analog audio input path comprising an analog to digital converter configured for receiving two analog audio signals and outputting a digital audio stream in Integrated Interchip Sound (I2S) format at twenty-four bits precision; (b) a digital audio input path, the digital audio input paths comprising a sample rate converter configured for receiving a two channels of audio and outputting a digital audio stream in I2S format at twenty-four bits precision synchronized and phase locked with the analog audio input path; (c) an address module configured for inserting a first address and a second address into unused portions of each I2S stream; (d) a multiplexer module configured for multiplexing the I2S streams as a time division multiplexed signal with an embedded clock; (e) a physical layer interface configured for transmitting the time-division multiplexed audio stream on a first communication path and control information on a second communication path.
