REMOTE AUDIO KEEP ALIVE FOR A WIRELESS DISPLAY

摘要

An apparatus and method is provided for improving initialization and synchronization of display devices to audio data. Current implementations to retain synchronization between a transmitter and a display use“Keep Alive”silent audio data stream in the format of the latest data stream on an interface between the transmitter and the display even when no data is available. Implementing the above solution in a system where the silent audio data stream is transmitted over a wireless link is bandwidth and power inefficient. The techniques provide an apparatus and method to efficiently generate and transmit silent audio data stream for maintaining synchronization.
