Abstract
In an embodiment, a transmitter generates a self-generated video signal when retrieving only audio input signal from an audio source to replace an video input signal expected by the HDMI system. In another embodiment, a transmitter sets a flag when retrieving only an audio input signal, wherein the flag configures preamble transmitted in control periods to allow audio data to be transmitted to a receiver without incorporated with video data.
