Abstract
Described herein are techniques which facilitate the automatic synchronization of audio and video signals between an entertainment device and a presentation device. A sensing device detects and records timing information from a video test pattern generated by an entertainment device and output by a presentation device. Using the timing information from the sensing device, the entertainment device synchronizes the audio and video signals it outputs to one or more presentation devices. The presentation device exhibits synchronized audio and video to a user.
