Abstract

A recording apparatus, a reproduction apparatus and a file management method are disclosed wherein, even if one of files recorded on a recording medium cannot be reproduced regularly, another file selected by the user can be reproduced normally. A file having a hierarchical structure formed from video data and audio data both in the form of compressed 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 the top side of the file.

First claim

What is claimed is:

1. A reproducing apparatus comprising:
an acquisition unit configured to acquire reference data regarding a plurality of media contents;
a selecting unit configured to select at least one of the media contents based on the reference data; and
a reproducing unit configured to reproduce the selected media content,
wherein the reference data has a hierarchical structure including a plurality of hierarchies, and the reference data comprises, in a higher hierarchy of the reference data, data about a type of a codec of the media content, a bit rate of the media content, width and height of a picture size of the media content, and identification for the media content, and the reference data comprises, in a lower hierarchy of the reference data, data about a timescale of the media content.

2. The reproducing apparatus according to claim 1 , wherein the reference data comprises:
frame rate of the media content, and
sampling frequency of the media content.

3. The reproducing apparatus according to claim 2 , wherein the reproducing apparatus has a processing capacity, and the reproducing unit reproduces the media content according to the processing capacity of the reproducing apparatus.
