Abstract (en)

[origin: WO2005117413A1] Measurement (531) of the relative timing between images and associated information (511, 513), for example video and audio. Image mutual event characteristics are recognized in the images and associated mutual event characteristics (521, 523) are recognized in the associated information. The image mutual events and associated mutual events are compared (531) to determine their occurrences, one relative to the other as a measure of relative timing (541, 551). Particularly operation with audio and video signals is described.
