摘要： In case of decoding by a software process, in the process 1, video data of a decoded frame corresponding to a management ID stored at the head of an output FIFO 4 at its time point is read out and outputted. In the process 2, audio data is decoded. In the process 3, the video data is decoded. The decoded video data is stored in a video frame buffer and its management ID is stored in the output FIFO 4 in the outputting order. When the process 3 cannot be finished, the process 3 is interrupted during the process and the image of the frame stored at the head of the output FIFO 4 is outputted. After that, when the process 2 is finished, the decoding process of the process 3 which was temporarily interrupted is restarted. In case of performing the encoding by the software process, an encoding amount of the video data as a processing target of the encoding is predicted. Subsequently, whether an empty capacity enough to store the data of the predicted encoding amount exists in a code buffer or not is discriminated. If it is determined that there is the empty capacity, the encoding is started and the video data in which the encoding was finished is deleted from the video frame buffer. The encoding is temporarily interrupted when a reading process or the like of the video data is performed.

摘要： A flexible software-based decoding system with decoupled decoding timing and output timing. In one embodiment, a computer software implemented method of decoding a data stream comprising encoded video data is provided. In this embodiment, the software method comprises the step of maintaining a number of already decoded and ready-for-output frames in a frame buffer. The method also comprises the step of decoding a first encoded frame of the data stream to generate an additional decoded frame. The method further comprises the step of outputting a first of the decoded frames before decoding of the first encoded frame is completed if the decoding step requires more time than a predefined frame output time to complete. Moreover, in this embodiment, the method comprises the step of adding the first additional decoded frame to the frame buffer. In this embodiment, real-time output is maintained irrespective of whether completion of the decoding step requires more time than the predefined frame output time for particular frames. In one embodiment, the method further comprises the step of decoding a second encoded frame of the data stream substantially immediately upon completion of the decoding step to generate a second additional decoded frame, provided that the completion of the decoding step requires more time than the predefined frame output time, and also the step of adding the second additional decoded frame to the frame buffer.

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.
