发明名称 Wireless clock regeneration and synchronization
摘要 A method and apparatus are described for regenerating a local clock within a wireless module and synchronizing the local clock with a wireless host clock. For one embodiment, the wireless module generates a local clock, counts the cycles of the clock during a common timing reference period maintained wirelessly between the wireless module and the host, receives a count of the host clock during the same common timing reference period, and adjusts the local clock signal based upon a comparison of the two counts. For one embodiment, the wireless module further receives timing references from the host and, in addition, receives packets of audio samples from the host accompanied by a timestamp, the timestamp based upon the host timing reference, and outputs the audio sample at the time designated by the timestamp.
