Abstract (en)
[origin: WO2004057613A1] A method for generating characteristic point information (CPI) for multilayer encoded audio/video data includes generating a CPI file. The CPI file includes at least a point type corresponding to at least one point in a clip, a presentation time corresponding to the point in the clip, and one or more offset points corresponding to the point in the base layer and one or more enhancement layers of the clip. The point identified by the offset in the base and enhancement layers of the clip all correspond to the same point in the clip.
