Problems solved by technology

If a jump process occurs, which requires a period of time between the process of jumping to a position away from a certain data reproduction position of the disc and the process of reading and reproducing data from the next read position, In this case, the above-mentioned increase in the time period often results in a gap in the reproduction
[0009] Thus, if the audio is read and reproduced in parallel with performing continuous reproduction of still images (browsable slide show) as described above, if the time required for jump processing is increased, then the A configuration that alternately reads image data and audio data in one pass has the problem of discontinuity in reproduced data

Embodiment Construction

[0144] Details of a data processing method, a data processing apparatus, an information recording medium, and a computer program will now be described with reference to the drawings. It should be noted that the descriptions are given in the order of the following items:

[0145] 1. Contents stored on disk

[0146] 2. Browsable slide show

[0147] 3. Jump processing and content storage format

[0148] 4. Content recording and reproduction processing

[0149] 5. The configuration that can flexibly set the reading rate

[0150] 6. Reproduction device configuration

[0151] [1. Contents stored on disk]

[0152] By adopting such a configuration that a prescribed recording format of image data and audio data is provided in the disc so as to perform prescribed data recording and reproduction processing, the present invention will be able to realize seamless reproduction by reducing jumps. Data is reproduced without interruption by taking the time required for jump processing th...

Abstract

The present invention provided a device and a method for deciding a data arrangement structure to guarantee seamless reproduction even when jumping occurs in a browsable slide show. The device is configured in such a manner that an allowable range of jumping of image and audio data clips necessary during data reading in a so-called browsable slide show for simultaneously performing continuous reproduction and audio reproduction of a still image is decided, and data arrangement conditions to store data in an information recording medium are decided based on the decided jumping allowable range information. Thus, a browsable slide show is realized as seamless reproduction processing having no data discontinuity. Further, a plurality of combinations of audio data and image reading rates are provided.

Description

technical field [0001] The present invention relates to a data processing method, a data processing device, an information recording medium, and a computer program. More specifically, the present invention relates to a data processing method, a data processing apparatus, an information recording medium, and a computer program for performing parallel reproduction of image data and audio data contained in different positions in a disc. In reproduction processing, seamless content reproduction is enabled by preventing a break in reproduction caused by jump processing that occurs during conversion and reading of each of image data and audio data. Background technique [0002] The recording medium may contain various software data including discs such as Blu-ray discs or DVDs (Digital Versatile Discs) obtained by applying blue laser light, such as music and the like. Audio data, image data of movies, etc., game programs, various applications, and the like. [0003] There are re...
