Abstract
A video processing system adaptively generates and processes volume/file structure and navigation data of different data format and converts data between different formats for decoding, recording and other applications. The system processes the volume/file structure and navigation data in distinct modes including (a) pre-processing, (b) contemporaneous and (c) post-processing modes. In addition, the system provides navigation information supporting navigation through different images of one or more video programs by parsing encoded packetized data representative of a sequence of individual images to determine parameters to support navigation through the sequence of individual images. The determined parameters are formatted into a predetermined data structure and incorporated into a pre-formed navigation data field.
