Abstract
Abstract A video processing system adaptively generates and processes volume/file structure and navigation data of different data format in distinct modes including (a) pre-processing, (b) contemporaneous and (c) post-processing modes for decoding, recording and other applications. The system processes a video program comprising encoded digital packetized data representative of a sequence of individual images and ancillary file structure and navigation data supporting navigation through image sequences. The system parses the packetized data to determine characteristics of individual images prior to storage and uses the characteristics for generating navigation information. The generated navigation information includes a predetermined element constrained to a selected sub-set of elements to reduce subsequent processing. The system also generates a menu including an item enabling User selection and initiation of a function associated with the video program using the generated navigation information.
