  • Patent number: 8005348
    Abstract: According to one embodiment, an information processing apparatus inputs motion picture data generated by encoding a motion picture, each frame image of the motion picture is formed by synthesizing a plurality of images, containing a plurality of image data corresponding to the plurality of images. The apparatus includes a decoding module which decodes each of the image data contained in the motion picture data, and a drawing module which synthesizes each decoded image data to form image data of each frame image. The drawing module includes a measurement module which measures a time period for synthesizing the image data and outputting the synthesized image data, and a frame rate control module which decrements a frame rate related to a composite processing of the motion picture data by reducing the number of composite processing target frames per unit time when the measured time period exceeds a predetermined value.

    Abstract: Methods and systems are provided to fast fill media players and buffers associated with media players. A bandwidth associated with initial startup of a media player is overloaded to rapidly fill the buffer and initiate the media player. Alternatively, multiple simultaneous data communication sessions are established with a media data source device, and the media data are concurrently received from the simultaneous sessions into the buffer or transferred of out the buffer at startup, thereby decreasing the latency associated with initiating the media player.

    Abstract: The present invention relates to a reproducing apparatus and a reproducing method, a data structure, a recording medium, a recording apparatus and a recording method, and a program that enable, in a case where offset information of a sub-image is arranged in a stream of a main image, easy realization of 3D display of the sub-image based on the offset information. A right-eye video stream includes offset metadata for generating offset information. In a data portion of each TS packet of the right-eye video stream, only any one of video data of an encoded right-eye main image and offset metadata is arranged. In a header of each TS packet of the right-eye video stream, transport priority, which indicates whether data arranged in the data portion of the TS packet is video data of an encoded right-eye main image or offset metadata, is described. The present invention can be applied to, for example, a reproducing apparatus that displays a sub-image in a 3D manner.

  • Patent number: 7995903
    Abstract: A recording and reproducing module records a signal (broadcast program) based on a first compression method to a recording medium, and during a period of time during which recording is not performed, reproduces the signal based on the first compression method, which has been recorded to the recording medium. Then, a transcoding module transcodes the signal based on the first compression method to a signal based on a second compression method. The signal based on the second compression method, whose transcoding has been completed, is recorded to the recording medium; and the signal based on the first compression method is erased from the recording medium. The controller refers to recording history information and sets a schedule including a target broadcast program to be transcoded and a time zone in which the target broadcast program is transcoded.

  • Publication number: 20110150433
    Abstract: A new approach is proposed that contemplates systems and methods to support video-aware screen capture and compression. More specifically, the video-aware approach first detects whether or when video content is being actively played back on a screen of a hosting device. If the video content is actively being rendered, the approach separates (segments) the screen content into static (non-video) content and video content, The approach then applies video-specific capture and compression methods to the video content of the screen and other suitable compression methods to the non-video content of the screen. The compressed static and video content of the screen are separately and independently transmitted across the network to remote computing devices and are then decompressed and processed to reconstruct screen of its original content for display at the screens of the remote computing devices.
