  • Patent number: 10582148
    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.

  • Patent number: 10529382
    Abstract: In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

  • Patent number: 9357231
    Abstract: In a system for visualizing a stereoscopic image by displaying separate video images for the left and right eyes, sub-picture data (GRD) is created for the left eye and displayed superimposed on left-eye video data (VDD) as a left-eye sub-picture without change. The right-eye sub-picture (106) is displayed by shifting the horizontal positions at which the sub-picture data created for the left eye is displayed by prescribed widths. For example, the sub picture may include a plurality of objects (GRD-1, GRD-2, . . . , GRD-N); shift widths (108, 110) of the horizontal positions of the left and right ends of the objects are individually set and stored in the sub-picture data for displaying the objects for the right eye. A sub-picture superimposed on a stereoscopic video image can thereby be rendered in the depth direction, and the data size of the sub-picture and the amount of computation required for its display can be reduced.
