Abstract

Provided is a data recording configuration employing the AVCHD format and capable of rapidly performing reproduction, edition, and additional write. In a configuration for performing data recording based on the data recording format having a predefined hierarchical managing configuration such as the AVCHD format, An index file containing index information for the recorded data stores particular information required for reproducing the recorded data or editing the recorded data or additionally writing data. With this configuration, upon production, edition, additional write of recorded data, it is possible to perform rapid processing without requiring read of various files to acquire information.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a computer program, each of which performs data recording processing and data playback processing. More specifically, the present invention relates to an information processing device, an information processing method, and a computer program, each of which is used to record data and play back data in a recording format having a hierarchical data management structure. Background technique [0002] As the recording capacity of disc-shaped recording media increases, video cameras that store moving images or still images on a disc instead of known recording tapes are available on the market. Since the disk-shaped recording medium is used in a random access form, any desired scene can be efficiently found from the recorded data. Since the disc-shaped recording medium operates in a non-contact manner, data access to the disc can be performed without phys...
