20100278517 | VIDEO DECODING DEVICE - A video decoding apparatus ( | 11-04-2010 |
20110013890 | RECORDING MEDIUM, PLAYBACK DEVICE, AND INTEGRATED CIRCUIT - A pair of main-view and sub-view video streams and a graphics stream are recorded on a BD-ROM disc. Metadata is provided in each GOP in the sub-view video stream. The metadata includes offset information. The offset information specifies offset control for a plurality of pictures constituting a GOP. Offset control is to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes, and to combine them separately with main-view and sub-view video planes. The sub-view video stream is packetized and multiplexed in a transport stream. A header of each TS packet includes a TS priority flag. TS packets containing the metadata have a different value of TS priority flag from TS packets containing sub-view pictures. | 01-20-2011 |
20110075998 | AV Data reproducing device, method for reproducing AV data, and recording medium for the same - An original stream file and an after-recording data file are managed as different files. In the original stream file, data is made up of sets of partial data (CU) divided in accordance with a predetermined interval. Likewise, in the after-recording data file, data is made up of sets of partial data (CA) divided in accordance with a predetermined interval. These sets of data are recorded onto a disc such that the after-recorded data (CA) is recorded in a region adjacent to a relevant original stream (CU). This allows reproduction and real-time after-recording with the use of a general MPEG-2 PS/TS decoder. Moreover, this allows realization of data recording that causes less interruption of reproduction when non-destructive editing is carried out with respect to an after-recorded result. | 03-31-2011 |
20110305443 | DISPLAY DEVICE AND METHOD, TRANSMISSION DEVICE AND METHOD, AND RECEPTION DEVICE AND METHOD - A device for displaying stereoscopic video images on a screen includes a receiving unit, signal processing unit, and display unit. The receiving unit receives stream data including left-view frames and right-view frames of stereoscopic images. The signal processing unit alternately extracts left-view frames and right-view frames from the stream data. Over one frame period of the stereoscopic video images, the signal processing transmits a pair of a left-view frame and a right-view frame when the control information indicates a 3D playback mode, and transmits only a left-view frame when the control information indicates a 2D playback mode. The display unit displays each frame transmitted from the signal processing unit for a predetermined time on the screen. | 12-15-2011 |
20120008924 | RECORDING MEDIUM, PLAYBACK DEVICE, AND INTEGRATED CIRCUIT - On a recording medium, stereoscopic and monoscopic specific areas are located one after another next to a stereoscopic/monoscopic shared area. The stereoscopic/monoscopic shared area is a contiguous area to be accessed both in stereoscopic video playback and monoscopic video playback. The stereoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in stereoscopic video playback. In both the stereoscopic/monoscopic shared area and the stereoscopic specific area, extents of base-view and dependent-view stream files are arranged in an interleaved manner. The extents on the stereoscopic specific area are next in order after the extents on the stereoscopic/monoscopic shared area. The monoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in monoscopic video playback. The monoscopic specific area has a copy of the entirety of the extents of the base-view stream file recorded on the stereoscopic specific area. | 01-12-2012 |
20120148218 | RECORDING MEDIUM, PLAYBACK DEVICE, AND INTEGRATED CIRCUIT - A recording medium according to an embodiment of the present invention includes a base-view stream and a dependent-view stream. The base-view stream is used for monoscopic video playback. The dependent-view stream is used for stereoscopic video playback 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 in monoscopic video playback, and the second file refers to the base-view stream in stereoscopic video playback. | 06-14-2012 |
20130279888 | TECHNIQUES FOR SYNCHRONIZATION OF AUDIO AND VIDEO - Techniques are described for determining whether a stream is in a stable state and permitting adjustment of the PTS value when the stream is in a stable state. The stream can be in a stable state when PTS values received over a period of time do not change unexpectedly. For example, when the stream is in a stable state, the PTS value for audio or video can be adjusted based on system buffer levels, i.e., over flow or under flow. The amount of adjustment of the PTS value can be based on whether the buffer level appears to be moving into greater overflow or underflow. In some cases, when the stream is not in a stable state, the audio is permitted to be played back at a sample rate and video is permitted to be played back at a frame rate instead of being controlled by PTS. | 10-24-2013 |
20160029075 | FAST SWITCHING OF SYNCHRONIZED MEDIA USING TIME-STAMP MANAGEMENT - Disclosed are various embodiments that facilitate fast switching of synchronized media using time-stamp management. A first media stream and multiple second media streams are obtained. The second media stream is time synchronized to the first media stream. The first media stream and one of the second media streams are decoded. Time-stamp management without decoding is performed for another one of the second media streams to facilitate fast switching to the other one of the second media streams when desired. | 01-28-2016 |
