  • Publication number: 20130057770
    Abstract: In order to realize efficient memory access by reducing frequency at which areas specified by different row addresses in the same bank in a memory are consecutively accessed, the data processing apparatus (10) performs mapping so as to store data (21) and data (22), which are the same data, with use of the first arrangement and the second arrangement, respectively, in different memory areas constituting a memory (20). When reading a portion of the data, a selecting unit (21) selects one of the arrangements that is more efficient in accessing the portion of the data based on an address range corresponding to the portion of the data according to each arrangement, and an access control unit (13) accesses a memory area corresponding to the selected arrangement. Here, the data (21) is mapped to a position different from a position of the data (22) in terms of relative positions with respect to boundary addresses of blocks each corresponding to the same row address in the same bank.

  • Patent number: 8390743
    Abstract: Systems and methods for the synchronization and display of video input signals. The input signals, associated with input channels, are received by a controller. On a frame-by-frame basis, the controller controls the writing of the input signals to, and the reading of the input signals from, a memory. A frame rate control module controls frame-level synchronization between the writing operations and reading operations of the controller so that when a frame is written to the memory is not simultaneously read from the memory. The controller writes video frames for each input channel to, and reads video frames for each input channel from, the memory on a channel-by-channel basis such that the video frames corresponding to each input channel are read and written independently of one another. This allows the input signals to be unsynchronized with one another without harming the writing operations, reading operations, and display of the input signals.

  • Patent number: 7768576
    Abstract: There is provided a multi-screen synthesis apparatus that can execute display of video data and update of an OSD image without causing a user to feel a visual sense of incongruity, and reduce system costs. Periodic video source data and aperiodic OSD image data are written into a unified memory reserved for planes. The video source data and the OSD image data are read from the unified memory, based on a synthesis layout, for simultaneous display on a single display in a synthesized state. Video data to be written into the unified memory is decimated in units of a frame on an input video source-by-input video source basis. The decimation of the data is controlled based on display priority of the video data determined based on a multi-screen display layout.

    Abstract: There is provided a moving picture processing device (100) that has a display unit (120), a main processor (150), a display control unit (160), and a main memory (180). Using an overall-moving-picture data item stored in the main memory (180), the display control unit (160) and the display unit (120) play the overall moving picture (AM1), whereby a plurality of sectional moving pictures (SM11 to SM14) is displayed. In other words, displaying one moving picture enables a plurality of moving pictures to be displayed. Therefore, by using the moving picture processing device (100), it is possible to simultaneously display more moving pictures than those determined depending on the device's capacity to play moving pictures.

  • Patent number: 7653128
    Abstract: An information processing apparatus for decoding compression-coded video data includes at least one decoder decoding the compression-coded video data, a supply controller controlling the supply of the compression-coded video data to the decoder, and a controller controlling processing executed by the supply controller and the decoder. The controller determines the order of decoding processing performed by the decoder so that, among pictures contained in a decoding processing unit for the decoding processing performed by the decoder, I-pictures and P-pictures are decoded before B-pictures. The controller selects pictures to be output from the decoder from among the pictures contained in the decoding processing unit on the basis of a playback speed instruction provided by a playback speed instruction unit.

  • Patent number: 7436891
    Abstract: An image data decompression apparatus for decoding blocks of motion compensated non-intra coded data uses a memory (14) storing reference picture data. A decoding processor (12) decodes a current block of a generated picture using lines of previously decoded image data from the memory (14) that are selected in dependence upon a motion vector (V1) for the current block. In order to improve access efficiency to the memory (14) the decoding processor (12) concatenates fetches into bursts for different sections of lines of previously decoded data that lie within a predetermined range within the memory addresses of the memory (14).

  • Publication number: 20080192147
    Abstract: An apparatus and method for generating compressed image data, and outputting decoded images using the compressed image data. A compressed image data generation unit receives and compresses image data taken from a first camera arranged to generate an additional image and inserts the compressed image data into a specified area of the compressed image data generated using a picture image received from a second camera arranged to generate an ordinary image. An image output apparatus receives the compressed image data including the compressed picture image data, determines whether the compressed picture image data exists. If the compressed picture image data are present, the apparatus decodes the image data to generate a three-dimensional stereoscopic image as output using the ordinary image and the additional image. However, if the image output apparatus is not capable of three-dimensional image generation, it only provides the ordinary image.
