Abstract:
Systems and methods of efficiently indexing a digitized video stream are presented. In one embodiment, the method comprises receiving a coded video stream containing non-scrambled frame location indicators and scrambled video data, filtering the non-scrambled frame location indicators, and generating a database used for indexing frames. In one embodiment, the apparatus comprises a processor such as a hardware and/or software capable of generating a database used for improving video playback functionality by way of filtering non-scrambled indicators that define the start of frames in a digitized video stream.
