Synchronizing an augmented reality video stream with a displayed video stream

摘要

A method and system for synchronising an augmented reality video stream with a displayed video stream includes: accessing an augmented reality video stream which corresponds to a displayed video stream and accessing synchronising metadata associated with the augmented reality video stream for synchronising the augmented reality video stream to the displayed video stream; the synchronising metadata includes processed key frames of the displayed video stream. Processed key frames are selected frames from the displayed video stream which have been processed to provide data usable to compare images of frames. The displayed video stream is tracked by capturing and processing a frame of the displayed video stream. The augmented reality video stream is synchronised to the displayed video stream by matching the captured and processed frame of the displayed video stream with a processed key frame of the metadata at a known location in the augmented reality video stream. The displayed video stream may be captured using a camera on the augmented reality device.
