SIGNAL PROCESSING METHOD AND VIDEO/AUDIO PROCESSING DEVICE

摘要

A video/audio processing device (10) divides a segment to subsegments to be the candidates of r segments at step S1, sorts the subsegments into groups of subsegments similar to one another at step S2, selects groups to be objects of signature from the sorted groups at step S3, selects one r segment from each selected groups at step S4, and calculates the weights of each selected r segment at step S5.
