<p>A data processing device comprises receiving units (100, 102) that receive video and audio data; a compression unit (101) that codes the received video and audio data for generating coded data complying with the MPEG2 system standards; an additional information generation unit (103) that generates additional information including attribute information that describes the attribute of each sample unit wherein reference information referencing the coded data and the VOBU of the coded data are a sample unit; and a recording unit(120) that records the coded data as a data file, and the additional information as an additional information file, both on the recording medium. The coded data can be decoded based on the standard of either the additional information file or the MPEG2 system.</p> |
