APPARATUSES AND METHODS FOR WIRELESS SYNCHRONIZATION OF MULTIPLE MULTIMEDIA DEVICES USING A COMMON TIMING FRAMEWORK

摘要

Apparatuses and methods for wireless synchronization of multiple multimedia devices using a common timing framework are disclosed. In one aspect, a wireless multimedia source device is configured to establish wireless connections with a plurality of multimedia sink devices. The wireless multimedia source device is further configured to calculate a correction time interval for each multimedia sink device based on a difference between a master program clock reference (MPCR) and a local program clock reference (LPCR) feedback signal from the multimedia sink device. Presentation time stamp (PTS) data is generated based on the correction time interval and provided to the multimedia sink device. In another aspect, a wireless multimedia sink device is configured to receive a correction time interval based on a difference between an MPCR for the multimedia source device and an LPCR for the multimedia sink device, and calculate an updated LPCR based on the correction time interval.
