<p><P>PROBLEM TO BE SOLVED: To realize techniques for increasing data access speed, while reducing the memory capacity necessary for reproducing or searching for image data or audio data recorded as a file. <P>SOLUTION: An apparatus recording image data and audio data as a file includes an image data encoding means, an image data code amount control means, an audio data encoding means, an audio data code amount control means, an image stream generating means, an audio stream generating means, a multiplexing means for multiplexing the generated image stream and audio stream, and a recording means for recording a stream multiplexed by the multiplexing means on a recording medium, wherein the image data code amount control means and the audio data code amount control means control the image data encoding means and the audio data encoding means so as to fix the lengths of the image stream and the audio stream for each unit to be multiplexed by the multiplexing means. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
