This invention relates to methods of abrupt scene change detection and fade detection for indexing of MPEG-2 and MPEG-4 compressed video sequences. Abrupt scene change and fade-detection techniques applied to signals in compressed form have reasonable accuracy and the advantage of high simplicity since they are based on entropy decoding and do not require computationally expensive inverse Discrete Cosine Transformation (DCT).
