  • Randomly accessible visual information recording medium and recording method, and reproducing device and reproducing method
    Patent number: 7801416
    Abstract: Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I1, P1, B1, B2, B3, B4, P2, . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.

  • IMAGE CODING APPARATUS WITH SEGMENT CLASSIFICATION AND SEGMENTATION-TYPE MOTION PREDICTION CIRCUIT
    Publication number: 20100208812
    Abstract: A segmenting section divides an input image into a plurality of segments. A hierarchizing section determines classes of the respective segments according to a predetermined criterion, and produces a class identification signal indicating the classes of the respective segments. A coding section encodes the segmented image signal into code data while changing the value of a coding control parameter for each of the segments in accordance with the class identification signal. Examples of the coding control parameter are a coding time interval and precision of quantization.

  • Crossbar switch, information processor, and transfer method
    Patent number: 7672305
    Abstract: Port input sections generate, when the head flits of a packet are stored in the first and second registers, first and second mediation request signals destined for a desired request destination, and further generate a first notification signal used to notify the presence or absence of the first mediation request signal destined for any request destination. Upon reception of a mediation result signal, the port input sections output the flit from the first register and sequentially forward flits to be stored in the first register and the second register, and the port output sections sequentially output the flit outputted from the first register of any one of the port input sections to the node.

    Publication number: 20100005070
    Abstract: Multimedia content containing moving pictures and audio is divided into multiple scenes and metadata is generated for each of the scenes obtained as a result of the division. It is possible to generate metadata containing scene structure information metadata that describes the hierarchical structure of the content in addition to scene section information and titles. Also, a name or an identifier of each descriptor contained in the metadata is described as hint information for manipulation of metadata composed of at least one descriptor describing semantic content, a structure, and characteristics of content.
