Abstract
A data file reproduction system has a data file supplying apparatus that extracts video data and audio data from a received data file, compresses the extracted video and audio data and produces a compressed data file containing the compressed audio and video data together with meta or navigation data determined from the data file for enabling navigation of the original data file. The compressed data file is then copy-protected. Upon request, the copy-protected compressed data file is communicated to a reproduction apparatus which decompresses the compressed audio and video data of the received copy-protected compressed data file, encodes the decompressed audio and video data and produces a copy-protected reconstituted data file containing the encoded audio and video data together with the meta or navigation data determined from the copy-protected compressed data file, so enabling navigation of the copy-protected reconstituted data file, the same as the original data file.
