Patent ID: 8743284

Claim:
A method in a handheld multimedia device, the method comprising: separating multimedia content into audio frames and video frames; adding a sequence number to at least one of the audio frames and at least one of the video frames; presenting the video frames on a user interface of the multimedia device; transmitting the audio frames to a wireless audio device, which is separate from the multimedia device; measuring and tracking a transmission delay associated with the transmission of the audio frames to the wireless audio device; assessing the synchronization between the audio and video frames using the measured transmission delay through a correlation of the sequence numbers added to the audio and video frames; and controlling the presentation of the video frames on the user interface, to reduce or eliminate a lack of synchronization, by delaying a transfer of video frames presented to the multimedia device in a manner that synchronizes the audio and video frames when the measured transmission delay of the audio frames exceeds a specified threshold.
