METHOD AND APPARATUS FOR WIRELESS CLOCK REGENERATION
Methods and systems for operating a wireless clock system for multimedia datastream transmission and display. Source clock frames are compared with a reference clock frames and the clock difference are transmitted to a wireless clock receiver which also receives the same reference clock frames. Source clock frames are re-constructed using the reference clock frames, clock difference information and the receiver's local clock system.
