Abstract

A data source sends a synchronization signal and information to several data sinks that use the synchronization signal and a specified parameter to determine when to process the information. The data source and data sinks may comprise wireless nodes such as, for example, a wireless audio source that sends multi-channel data to a pair of wireless earpieces. The wireless earpieces use the synchronization signal and a latency interval to determine the appropriate time to output audio based on the audio channels.

Description

[0001] Claiming Priority Based on 35 U.S.C.§.119 [0002] This application claims the benefit and priority of commonly owned U.S. Provisional Patent Application No. 61 / 050,479, filed May 5, 2008, assigned Attorney Docket No. 072293P1, the disclosure of which is incorporated by reference Incorporated into this article. technical field [0003] This application relates generally to wireless communications, and particularly, but not exclusively, to synchronization of wirelessly transmitted information. Background technique [0004] A signal processing system consists of several components that perform tasks in a synchronous mode. For example, in a multi-channel audio system, a given sample of an audio stream on one channel is output at substantially the same time as a corresponding sample of an audio stream on another channel. Also, in a control system, the activation of one component occurs at a specific moment relative to the activation of another component. Likewise, in a...
