Problems solved by technology

Thus, the correspondence between the sections that should be read before and after the far jump and the parts of the video stream that should be saved in them is complicated
As a result, it is difficult to obtain a file structure that can easily achieve fast reading of these sections

Embodiment approach 1

[0095] figure 1 It is a schematic diagram showing a home theater system using the recording medium according to Embodiment 1 of the present invention. This home theater system adopts a playback method of 3D video (stereoscopic video) using parallax video, and in particular, a time-division method is adopted as a display method (see for details). refer to figure 1 , the home theater system takes the recording medium 101 as the reproduction object, and includes the reproduction device 102 , the display device 103 , the lenticular glasses 104 and the remote controller 105 .

[0096] The recording medium 101 is a read-only Blu-ray Disc (registered trademark) (BD: Blu-ray Disc), that is, a BD-ROM disc. The recording medium 101 may be another portable recording medium, for example, an optical disc of another format such as a DVD, a removable hard disk drive (HDD), or a semiconductor memory device such as an SD memory card. The recording medium, that is, the BD-ROM disc 101 sto...

Embodiment approach 2

[0652] Hereinafter, as Embodiment 2 of the present invention, the recording device and recording method for the recording medium according to Embodiment 1 of the present invention will be described.

[0653] This recording device is what is called a so-called writing device. The writing device is usually set up in the production studio of the movie content for distribution and used by the writing staff. According to the operation of the writer, the recording device first converts the movie content into a digital stream conforming to the compression encoding method of the MPEG standard, that is, an AV stream file. The recording device then generates the script. The scenario is information that specifies the playback method of each title included in the movie content, and specifically includes the above-mentioned dynamic scenario information and static scenario information. Next, the recording device generates a volume image or an update kit for a BD-ROM disc from the above-me...

Embodiment approach 3

[0672] Figure 65 It is a functional block diagram of the integrated circuit 3 according to Embodiment 3 of the present invention. refer to Figure 65 , the integrated circuit 3 is mounted in the playback device 102 of the first embodiment. Here, the playback device 102 includes a media interface (IF) unit 1 , a memory unit 2 , and an output terminal 10 in addition to the integrated circuit 3 .

[0673] The media IF unit 1 receives or reads data from an external media ME, and sends it to the integrated circuit 3 . This data particularly includes the data on the BD-ROM disc 101 of the first embodiment. Types of media ME include disk recording media such as optical disks and hard disks, semiconductor memories such as SD cards and USB memories, broadcast waves such as CATV, and networks such as Ethernet (registered trademark), wireless LANs, and wireless public lines. The media IF unit 1 includes a disk drive, a card IF, a CAN tuner, an Si tuner, and a network IF according to...

Abstract

A recording medium includes a base view stream and a dependent view stream. The base view stream is utilized for the reproduction of a planar view image. The dependent view stream is utilized for the reproduction of a stereoscopic view image in combination with the base view stream. The recording medium further includes a first file and a second file. The first file refers to the base view stream during the reproduction of the planar view image. The second file refers to the base view stream during the reproduction of the stereoscopic view image.

Description

technical field [0001] The present invention relates to reproduction technology of stereoscopic video, that is, 3-dimensional (3D) video, and particularly relates to a file structure of stream data on a recording medium. Background technique [0002] In recent years, general interest in 3D images is increasing. For example, in amusement parks, entertainment attractions using 3D images are gaining popularity. In addition, movie theaters showing 3D video movies are increasing all over the country. As interest in such 3D video images increases, the development of technologies for enabling reproduction of 3D video images at home is progressing. In this technology, it is required to record 3D video content in a high-quality state on a removable recording medium such as an optical disc. Furthermore, compatibility of the recording medium with 2D playback devices is required. That is, it is desired that the 2D playback device be able to play back 2D video images from the 3D vide...
