Recording apparatus, reproduction apparatus and file management method

摘要

A recording apparatus, a reproduction apparatus and a file management method are provided which are arranged to reproduce at least some files from a recording medium from a set of files which have been compression encoded and recorded on the recording medium. Files are partially reproduced to acquire information as to whether they can be decoded normally or not. A table of files is displayed based on the information. Even if one of the files recorded on the recording medium is difficult to decode normally, another one of the files selected from the table may be decoded. To provide the arrangement, a file having a hierarchical structure formed from compressed video data and audio data together with information necessary for processing of the video data and audio data is produced and recorded on a predetermined recording medium. Upon production of the file, information regarding decoding of the video data and audio data is disposed collectively on a top side of the file. Embodiments of the present invention can be applied to processing of movie files recorded, for example, in the QuickTime format.
