  • Method for efficient MPEG-2 transport stream frame re-sequencing
    Patent number: 7027713
    Abstract: A method and apparatus for creating a trick play video display from an MPEG-2 digital video transport stream are described. A trick play transport stream frame sequence template for each transport stream frame sequence and trick play video display mode supported by a video recorder is stored in the recorder. When the recorder receives an input transport stream frame sequence, the sequence is identified and template corresponding to that sequence and the selected trick play display mode is selected. The template is used to identify frames of the input transport stream to be appended to the trick play display transport stream frame sequence. When the trick play transport stream frame sequence is constructed the program clock reference, presentation time stamps and decoding time stamps associated with the frames are updated from information in the template.

  • System and method for reproducing a video session using accelerated frame playback
    Patent number: 7027708
    Abstract: A client for reproducing a video session includes a memory and a processor coupled to the memory. The memory stores a first video frame that includes first video data, a first video sub-frame comprising second video data that is different from the first video data, and a second video sub-frame comprising third video data. The processor generates a second video frame using the first video frame and the first video sub-frame, wherein the third video data is different from the video data of the second video frame. The processor further generates a third video frame using the second video frame and the second video sub-frame, and displays the first video frame.

  • Image data reproducing method, image data reproducing apparatus, image data recording method and image data recording apparatus
    Patent number: 7024102
    Abstract: A method of reproducing first images and second images simultaneously, synchronizing them with each other. The method includes the processes of: reading first image data representing the first images and second image data representing the second images from a recording medium; storing the first image data into a first memory device and storing the second image data into a second memory device; and separately and simultaneously decoding the first image data and the second image data by using a first decoding device and a second decoding device. In this method, each of the first image data and the second image data is divided into a plurality of data units each having an equal time length and an equal data size, and each of the data units of the first image data and each of the data units of the second image data are alternately arranged on the recording medium.

  • Coded picture data reproducing apparatus
    Patent number: 7010219
    Abstract: A coded picture data reproducing apparatus which is able to repetitively reproduce picture data starting at a designated start-frame is provided. The coded picture data reproducing apparatus is capable of reproducing predictively coded MPEG system picture data by using a correlation between frames and thus capable of repetitively reproducing frames across a designated start-position and an end-position. When a frame corresponding to a B-picture to be reproduced in preceding a frame corresponding to an I-picture, among picture data in GOPs in reproduction is designated as a start-frame, a controller Mp controls to execute the repetitive reproduction across the start-frame and an end-frame by controlling an optical pickup Pu, a memory Dmp for storing picture data and an MPEG decoder Mpg to fetch the B-picture of the frame corresponding to the decoded start-frame.

  • Method and apparatus for timestamping a bitstream to be recorded
    Patent number: 7006756
    Abstract: A set top box can be connected to a DVD Streamer via an IEEE1394 interface which contains means to timestamp data and to strip off these timestamps again, using them for timing regeneration. The DVD stream also must regenerate the timing of data packets as it was upon recording, when these packets are played back. The streamer could also use its own timestamps and strip them off again when replaying. So, in total, there is an in-series connection between two time stamping and time regeneration mechanism which introduces jitter accumulation.

  • DVD random shuffle method
    Patent number: 6987925
    Abstract: A method for randomly shuffling through a large set of video and/or audio clips using a media player and related readable media is disclosed. In one form, the total number of entries in the set of clips is a prime number. An initial current clip value is randomly generated between one and the total number of entries in the set. A jump value is randomly generated between one and the total number of entries in the set minus one. To select a subsequent current clip, the current clip value and the jump value are added together. This sum is divided by the number of entries in the set. The remainder from this division is saved as the subsequent current clip value.

  • Method for moving image playback and apparatus therefor
    Patent number: 6980733
    Abstract: Image data is sequentially read out in units of frames from a storage apparatus storing NTSC images, divided into even and odd fields for each frame, and stored into a frame buffer. A judgment is made as to whether the even field of the currently read-out frame is the same image as the even field of the immediately previous frame, and if the images are the same image data is read out without a judgment being made for 4 frames starting from the next frame and 1 frame is removed so as to form a frame from the odd field of the currently read-out frame and the even field of the next read-out frame, a non-interlaced display being made at an interval of 1/24 for 4 the next 4 four frames that include this frame.

  • Image sensing apparatus which carries out optimum exposure control of subject
    Patent number: 6980251
    Abstract: The state of exposure of a video zone corresponding to position information from a two-dimensional position selecting circuit that allows a photographer to select a desired video zone is detected, an exposure correction is performed by an exposure control circuit based upon a signal indicative of the detected state, and the state of exposure which prevails when optimum exposure has been attained is maintained. As a result, the state of exposure of a subject is corrected to an optimum exposure and the optimum exposure of the subject is maintained even if the state of exposure of the surroundings change owing to a change in zoom magnification or movement of the subject.
