System and method for synchronization of isochronous data streams over a wireless communication link

摘要

A transmitter ( 500 ) is provided for transmitting host data over a wireless channel. The transmitter ( 500 ) includes a free-running timer ( 560 ) that provides a series of increasing free-running timing values; a host interface circuit ( 510 ) that receives host data from a local host circuit and a first free-running timing value from the series of increasing free-running timing values; a detection circuit ( 530 ) for detecting a global synchronizing event and receiving a second free-running timing value from the series of increasing free-running timing values, and for placing the host data and the first free-running timing value into a host interface packet; and a wireless transceiver ( 530 ) for adding the second free-running timing value and an identifier for the global synchronizing event to the host interface packet to form an air link frame, and transmitting the air link frame over a wireless channel to a remote wireless device.
