20100086285 | PLAYBACK DEVICE, RECORDING MEDIUM, AND INTEGRATED CIRCUIT - Disclosed is a playback device capable of seamlessly playing back 3D and 2D videos. The playback device plays back 3D video streams including a base-view video stream and a dependent-view video stream. When performing stereoscopic playback using the 3D video streams, the playback device outputs picture data pieces obtained by decoding the base-view video stream and the dependent-view video stream to a display device. When performing 2D playback using the 3D video streams, the playback device outputs each of picture data pieces obtained by decoding the base-view video stream to the display device twice in succession. This way, an output frame rate at which the 2D playback is performed matches an output frame rate at which the stereoscopic playback is performed. | 04-08-2010 |

20100260489 | RECORDING MEDIUM, PLAYBACK DEVICE, PROGRAM, PLAYBACK METHOD, AND RECORDING METHOD - Recorded on the recording medium (BD-ROM) is an AV stream that is obtained by multiplexing a video stream and one or more audio streams. MOVIE objects are scenarios showing playback procedures of video data described using playback device-oriented commands. In addition to the MOVIE objects, enhanced-mode scenarios (Java and WebPage objects) are also recorded on the recording medium. These enhanced-mode scenarios, each of which is described in the Java language or a markup language, show control procedures with respect to playback devices. The Java and WebPage objects are capable of taking over register setting values set by MOVIE objects, and extracting parts of video data played by MOVIE objects. | 10-14-2010 |
20110091185 | PLAYBACK APPARATUS, PROGRAM, AND PLAYBACK METHOD - When playing an AV Clip recorded on a BD-ROM, a judgment is made, for each elementary stream, which of a plurality of predetermined conditions the elementary stream satisfies. The plurality of predetermined conditions include (a) a condition that a playback apparatus has a capability of playing the elementary stream, (b) a language attribute of the elementary stream matches a language setting of the playback apparatus, and (c) a channel attribute of the elementary stream is surround sound and the playback apparatus has a surround output capability. The playback apparatus assigns a priority to each elementary stream based on which conditions the elementary stream satisfies, selects an elementary stream having a highest priority, and plays the selected elementary stream. | 04-21-2011 |
