Abstract
In general, a system and method for routing audio over a Digital Visual Interface (DVI) link is described herein. In one embodiment, the system comprises a a Digital Audio Interface (DAI) transmitter and a DAI receiver. Coupled to a fourth channel of the DVI link that transmits a pixel-rate clock signal, the DAI transmitter modulates the pixel-rate clock signal by input digital audio. The DAI transmitter sends the modulated clock signal to the DAI receiver. The DAI receiver recovers the digital audio from the modulated pixel-rate clock signal.
