Abstract

A compressed digital video bitstream is partially decoded to extract certain data (e.g., inter/intra block field data, motion vector data, and/or DCT coefficient data). The extracted data is then analyzed (for a single frame or over multiple frames) to characterize picture content. For example, the inter/intra block field data can be analyzed to detect the existence of scene changes and camera switches. In addition to inter/intra block field data, patterns in the motion vector data can also be characterized to detect the existence of camera pans and zooms and the occurrence of persons/objects moving within or entering or leaving a scene. Intra/inter block field data and motion vector data can also be used to detect the occurrence of still text, slides, and pictures within a compressed bitstream. In addition, DCT coefficient data can be used to detect the existence of text and raster displays within the field of view.
