Wireless video clock synchronization to enable power saving
In a wireless video system, the clock rate for wirelessly transmitting the video data from the transmitting device should be identical to the clock rate for receiving the video data at the receiving device. But the two devices have separate clocks, whose frequencies may drift apart over time, leading the video buffer to be over run or under run. Clock synchronizing messages to prevent this may be sent at short intervals when clock synchronization is first being acquired, and at larger intervals after clock synchronization has already been achieved and is merely being maintained.
