摘要： A multimedia decoder unit having error concealment and fast muting capabilities. The audio decoder provides error concealment using a dynamic recovery delay that is based on the error rate of an input digital bitstream and also uses frame repeating. The decoder allows fast audio muting whereby audio can be muted within two audio frames of a mute signal that immediately freezes the video frame, e.g., a channel change. With respect to the dynamic recovery delay, a template of fixed length is used to inspect the last frames within the template. If error is found, then the error sum is used as an index into a table length which provides a dynamic template length. Error within the dynamic template length is computed and if larger than a tolerance, the current frame is muted. This allows the recovery delay to be adaptive and based on the error rate while still allowing mute merging. Muting the current frame can be achieved by repeating the previous frame but the delay data of the last block of the previous audio frame is added to the first block of the repeated audio frame to provide a smooth frame interface. In response to a mute command, the decoder zeros the audio output bitstream stream to provide zero frames at the audio output buffer (AOB). In addition, the decoder also directly zeros audio frames in the AOB that lie between its the read and write pointers to guarantee that only two frames of audio be played after the mute signal.

摘要： A transmission apparatus includes a first data stream generation unit, a second data stream generation unit, and a data transmission unit. The first data stream generation unit generates an image compression data stream. The second data stream generation unit generates a audio compression data stream to which specific information which is not directly related to audio data is added. The data transmission unit multiplexes the image compression data stream generated by the first data stream generation unit and the audio compression data stream generated by the second data stream generation unit, and transmits the resulting data stream.

摘要： A method of decoding closed caption disparity data, involves a TV receiver receiving closed caption disparity data for a 3D display encoded as a sequence of frame interval/slope change pairs, with the frame interval representing a designated number of frames over which each linear function representing disparity is to be applied paired with a value indicating a change in slope from the slope of a preceding segment. A first segment in the sequence presumes a predetermined slope as a reference. A sequence of caption data packets specifies a closed caption display window containing closed caption text. The disparity value is used in each frame to determine a horizontal offset of left and right eye views of the CC display that establishes the closed caption display window's perceived z-axis position. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： The present invention realizes a video coding apparatus that is simple in configuration and can avoid video display quality deterioration due to an overrun of video coding processing. The video coding apparatus is provided with a coding means for bringing video into coding processing on a frame basis with a first coding processing method; a processing time detecting means for detecting coding actual processing time required for coding processing on the frame; a delay calculating means for calculating processing delay time of coding processing on the frame based on coding predicted processing time given to the coding processing and the coding actual processing time; a coding load controlling means for, in a case where the processing delay time on the frame is greater than or equal to a predetermined threshold value, causing a subsequent frame to undergo coding processing with a second coding processing method bearing coding processing load lower than in said first coding processing method, and thereby processing time of frames after occurrence of an overrun is shortened for recovery from the overrun so that a frame skip due to occurrence of an overrun is prevented to enable avoidance of video quality deterioration.

摘要： A reception device with a 3D function can appropriately acquire corresponding disparity information together with data of overlapping information.A first private data stream (a 2D stream) including data of overlapping information and a second private data stream (a 3D extension stream) including disparity information are included in a multiplexed data stream. Association information associating the first private data stream with the second private data stream is included in the multiplexed data stream. For example, identification information which is common to descriptors describing information related to both of the streams is described as the association information. A reception device with a 3D function at a reception side can efficiently and appropriately extract and decode both of the streams based on the association information.

摘要： [Object] To enable consistency to be maintained in perspective with the objects in an image when performing superimposing display of ARIB format captions (caption units).[Solution] Caption data of each caption unit is inserted, as caption data (caption code) of a caption text data group, into a caption data stream. Also, disparity information (disparity vector) of each caption unit is inserted, as caption management data (control code) of a caption management data group, in the caption data stream. Since the caption data and disparity information are correlated, suitable disparity can be provided at the reception side to the caption units to be superimposed on the left eye image and right eye image.

摘要： [Object] To enable a receiver compatible with MVC to adequately handle dynamic change in the contents of distribution and to perform correct stream reception.[Solution] A broadcasting station 100 transmits a first transport stream TS1 and a second transport stream TS2 in a time-sharing manner. The TS1 includes the video elementary streams of a base view and a predetermined number of non-base views. The TS2 includes a video elementary stream of two-dimensional (2D) image data. Stream association information for associating the base view and a predetermined number of non-base views is inserted into the TS1. A receiver 200 recognizes that the TS1 has been transmitted, based on the stream association information, and also recognizes association between the base view and non-base views. The receiver 200 can adequately handle dynamic change of the TS1 and TS2, i.e., dynamic change in the contents of distribution, and perform correct stream reception.
