20090208189 | PLAYBACK DEVICE, RECORDING DEVICE, PLAYBACK METHOD, AND RECORDING METHOD - A playback device for playing back a playlist. The playback device determines, as a current sub-playitem, a sub-playitem that is optimum for the current sub-playitem each time the current playitem changes. The playback device continues a playback of a playitem when a clip file being referred to by the current sub-playitem has been downloaded and is in the Enable state in the local storage; and stops, by issuing a DataStarved event, the playback of the playitem when the clip file being referred to by the current sub-playitem is in a missing state or an invalid state in the recording medium. | 08-20-2009 |
20090279869 | RECORDING MEDIUM, RECORDING DEVICE, RECORDING METHOD, AND PLAYBACK DEVICE - A recording medium having recorded thereon one or more pieces of playlist information each of which includes a stream table including multiple stream entries. Each audio stream has been encoded in one of a mandatory format that is an encoding format decodable by a playback apparatus with any version number, and an optional format that is an encoding format decodable by a playback apparatus with a predetermined or higher version number. In a first-type stream table, a stream entry corresponding to an audio stream encoded in the optional format is immediately subsequent, in the order of the stream entries, to a stream entry corresponding to an audio stream encoded in the mandatory format, the audio stream encoded in the optional format and the audio stream encoded in the mandatory format having been encoded from a same audio source and having a same language code and a same number of channels. | 11-12-2009 |
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 |
20130191861 | BROADCASTING-COMMUNICATIONS COLLABORATION SYSTEM, DATA GENERATING APPARATUS, AND RECEIVING APPARATUS - A data generating apparatus | 07-25-2013 |
20130235270 | PLAYBACK APPARATUS, PLAYBACK METHOD, INTEGRATED CIRCUIT, BROADCAST SYSTEM, AND BROADCAST METHOD - The present invention provides a playback apparatus for playing back one combination video by combining a broadcast video with any additional video not determined by a fixed position relative to the broadcast video. The playback apparatus comprises: a first receiving unit that receives, via a broadcast wave, a broadcast video composed of broadcast images, each broadcast image being a portion of a frame image among a plurality of frame images constituting the original video; a second receiving unit that receives an additional video composed of remaining images, each remaining image being the remaining portion of the frame image; an arrangement information acquiring unit that acquires arrangement information indicating an arrangement of the broadcast image and the remaining image in the frame image; and a playback unit that reproduces and plays back the frame images by arranging the broadcast images and the remaining images based on the arrangement information. | 09-12-2013 |
20130314514 | DISPLAY APPARATUS, 3D GLASSES, AND 3D-VIDEO VIEWING SYSTEM - A state setting unit stores a parameter indicating the state of a display device. A packet analyzing unit refers to the parameter to receive a broadcast stream, and analyzes management packets contained in the broadcast stream. A decoding unit uses a result of the analyzing to extract packets constituting broadcast content from the broadcast stream and decode the packets into video frames. A display unit displays video images represented by the video frames. A 3D video image detecting unit uses a result of the analyzing to determine whether broadcast content to be displayed contains 3D video images or not. A transmitter unit transmits a notification signal to a pair of 3D glasses when the 3D video image detecting unit detects that the broadcast content contains 3D video images. A notifying unit operates to urge the viewer to use the pair of 3D glasses in response to the notification signal. | 11-28-2013 |
20140050458 | RECORDING MEDIUM, REPRODUCTION DEVICE, AND RECORDING DEVICE - A recording medium has a main-view stream, a sub-view stream, and an extended stream recorded thereon. The main-view stream contains a main-view video stream constituting main views of stereoscopic video images, and is divided into a plurality of main-view extents arranged on the recording medium. The sub-view stream contains a sub-view video stream constituting sub-views of the stereoscopic video images, and is divided into a plurality of sub-view extents arranged on the recording medium. The extended stream contains extended data to be used in combination with the main-view stream, and is divided into a plurality of extended extents arranged on the recording medium. Between an adjacent pair of the plurality of extended extents, at least two each of the plurality of the main-view extents and the plurality of the sub-view extents are placed in a continuous, interleaved arrangement. | 02-20-2014 |
20140115472 | RECORDING MEDIUM, PLAYBACK DEVICE, RECORDING DEVICE, PLAYBACK METHOD AND RECORDING METHOD FOR EDITING RECORDED CONTENT WHILE MAINTAINING COMPATIBILITY WITH OLD FORMAT - A rewritable recording medium on which Index.bdmv is recorded in the BDMV directory. The Index.bdmv includes editability_flag and extended_editability_flag. When the editability_flag is set ON, it indicates that the recording medium is treated as an editable medium by a legacy device which does not support recording and editing of stereoscopic video. When the editability_flag is set OFF, it indicates that the recording medium is treated as a non-editable medium by the legacy device. When the extended_editability_flag is set ON, it indicates that the recording medium is treated as an editable medium by a non-legacy device even when the editability flag is set OFF, where the non-legacy device supports recording and editing of stereoscopic video. | 04-24-2014 |
