Information processing apparatus and method, and recording medium and program used therewith

Abstract

An information processing apparatus controls an encoder which performs encoding processing on each of data items in access units forming video data while switching encoding types. The apparatus includes a detector which controls the encoder to perform first path encoding on the video data in accordance with first encoding conditions, the first path encoding being included in the encoding processing, and which detects, as information for use in second path encoding being to be performed on the video data and being included in the encoding processing, encoding types and data amounts of data items in the access units forming the resultant first encoded video data obtained by controlling the encoder to perform the first path encoding.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present invention contains subject matter related to Japanese Patent Application JP 2004-255673 filed in the Japanese Patent Office on Sep. 2, 2004, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to information processing apparatuses and methods, and recording media and programs used therewith, and, in particular, to an information processing apparatus and method which generate encoded video data so that the recording capacity of a recording medium for the encoded video data can be efficiently used up, and which record the encoded video data in the recording medium, and to a recording medium and program used therewith. [0004] 2. Description of the Related Art [0005] In authoring apparatuses used in sites where recording media, such as optical discs, are created, each of video data items and audio data items is encod...

AI Technical Summary

Benefits of technology

[0059] As described above, according to an embodiment of the present invention, encoded video data can be generated. In particular, encoded video data can be generated so that the capacity of a recording medium can be efficiently used up.

[0060] In addition, according to an embodiment of the present invention, encoded video data can be recorded in a recording medium so that the capacity of the recording medium can be efficiently used up. In other words, a recording medium having encoded video data recorded therein so that a recording capacity is efficiently used up.

Problems solved by technology

However, an authoring apparatus of the related art has a problem in that, even if the techniques of the related art in Japanese Unexamined Patent Application Publication Nos. 11-004445 and 11-346365, and Japanese Patent Publication No. 3253971 are utilized in combination, it is difficult to generate encoded video data so that the capacity of a recording medium is efficiently used up.

A first cause of the problem is that, in the technique in Japanese Unexamined Patent Application Publication No. 11-004445, the following problem occurs.
