Description

The present invention relates to a disk device and an information reproducing device for reproducing information recorded on a recording medium such as a DVD (Digital Versatile Disc) capable of recording an audio file and a still image file, and in particular, recorded on a recording medium such as a DVD. The present invention relates to a disc playback device and an information playback device that play back an audio file and a still image file simultaneously.

In general, audio files such as MP3 (Moving Picture Coding Experts Audio Layer 3) files and still image files such as JPEG (Joint Photographic Coding Experts Group) files and the like recorded on a recording medium such as a DVD are reproduced. The information reproducing apparatus can reproduce an audio file and a still image file at the same time. However, when the playback time differs between an audio file such as an MP3 file recorded on a recording medium such as a DVD and a still image file such as a JPEG file, the playback time is short during simultaneous playback of the audio file and the still image file. However, there is a problem in that the reproduction of the first file is finished first, and only the file having the longer reproduction time is reproduced, and the simultaneous reproduction of the audio file and the still image file cannot be continued.
As background technology, the display time of the still image number corresponding to the still image is acquired from the management information, and the time search is performed using the display time so that the still image is displayed in the previous / next display, random display, and program display. There was a thing (for example, refer to patent documents 1).
Also, a playlist that simultaneously plays video, audio, and still images is recorded on the same recording medium together with video, audio, and still image data, and each video, audio, and still image data is played back based on the playlist. There was something like that (see, for example, Patent Document 2).
Further, the recording data is read from the optical disc, the still image data in the read recording data is stored in the still image data storage unit, and stored in the still image data storage unit when the recording data of the optical disc is reproduced. There is one in which still image data is read to display a still image (for example, see Patent Document 3).
