no. 1 Embodiment approach

[0081] Hereinafter, embodiments of a playback device including means for solving the above-mentioned problems will be described with reference to the drawings. First, the principle of stereoscopic viewing will be briefly described.

[0082] Usually, due to the positional difference between right eye observation and left eye observation, there are some differences in viewing modes between the image observed by the right eye and the image observed by the left eye. Utilizing this difference, people can recognize the image seen by the eyes as a stereoscopic image. In the case of performing stereoscopic display, the parallax of a person is used to make a two-dimensional image look like a three-dimensional image.

[0083] Specifically, in images displayed on a plane, there is a difference between the image for right eye observation and the image for left eye observation, which is equivalent to the difference in viewing methods due to human parallax. These images make it appear as ...

no. 2 Embodiment approach

[0448] In the second embodiment, a playback method and a playback device will be described when playback of 3D video images stored in a BD-ROM cannot be decoded due to missing pictures.

[0449] Figure 48 The upper part shows examples of pictures that are left-view video streams and right-view video streams during 3D video playback in order of display, and shows that there are pictures that cannot be decoded due to any abnormalities such as syntax errors during playback. A picture that cannot be decoded due to any abnormality such as a syntax error is called a missing picture 6501 . If there is a missing picture 6501 among the pictures in the right-view video stream, if the missing picture is displayed, the user will feel a great sense of discomfort.

[0450] Therefore, if Figure 48 As shown in the lower row, when there is a missing picture 6501 in the right-view video stream during 3D video playback, the playback device according to the second embodiment displays, instead...

no. 3 Embodiment approach

[0459] In the third embodiment, a playback method and playback device for temporarily stopping (pausing) processing of 3D video images stored in a BD-ROM will be described.

[0460] In the playback of 2D video images, in the case of a playback stop command to perform playback based on an instruction from the user, as in Figure 54 The playback device shown decodes 2D video pictures at the time of pause, and outputs the pictures at the frame rate of the video stream until a pause release command is issued. In the playback of 3D video images, in the case of a temporary stop command to perform playback according to the command from the user, there are the following two methods, namely: Figure 55 As shown in (a), a certain picture in the left-view video or right-view video at the time of temporary stop is decoded, and the picture is output until the method for canceling the temporary stop command; and if Figure 55 As shown in (b), a right-view video picture paired with a left-v...

Abstract

Provided is a reproduction device which can seamlessly reproduce a 3D video and a 2D video. The reproduction device reproduces a 3D video stream containing a base view video stream and a dependent view video stream. When performing a 3D reproduction by using a 3D video stream, picture data obtained by decoding the base view video stream and the dependent view video stream is outputted to a display device. When performing a 2D reproduction by using a 3D video stream, each picture data obtained by decoding the base view video stream is outputted to the display device twice repeatedly. Thus, the output frame rate in the 2D reproduction is converted in to the same frame rate as the output frame rate in the 3D reproduction.

Description

technical field [0001] The present invention is an invention related to the technical field of playback technology of 3D video and 2D video. Background technique [0002] In recent years, with the increase of movie theaters capable of viewing 3D images stereoscopically, a technique for storing 3D images on optical discs with high image quality has been pursued. [0003] When storing 3D video images on an optical disc, playback compatibility with playback devices capable of storing only 2D video images (hereinafter referred to as "2D playback devices") is sought. If the 2D playback device cannot reproduce the 3D video as 2D video from an optical disc storing the 3D video, it is necessary to produce two types of 3D disc and 2D disc for the same content, which increases the cost. Therefore, an optical disc storing 3D video is pursued and reproduced as a 2D video by a 2D playback device, and as a 2D video in a playback device capable of playing back 2D video and 3D video (herei...
