  • Randomly accessible visual information recording medium and recording method, and reproducing device and reproducing method
    Patent number: 8897624
    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.

  • RECORDING MEDIUM, REPRODUCING APPARATUS, AND REPRODUCING METHOD
    Publication number: 20140341539
    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.
