  • Publication number: 20140178040
    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.

  • Publication number: 20140169762
    Abstract: A video image information playback method and a video image information playback device with which user convenience can be obtained at the start of resume playback. The video image information playback method is a method of playback of a recording medium on which virtual-machine-based content has been recorded. During normal playback of the virtual-machine-based content, a program running on a virtual machine and a decryption program that decrypts encrypted virtual-machine-based content perform decryption processing for the virtual-machine-based content while exchanging data. After suspension of playback of the virtual-machine-based content, at the start of resume playback, which is executed following an instruction to resume playback, a proxy program is launched in place of the program that runs on the virtual machine. The proxy program and the decryption program perform playback of the video image of the virtual-machine-based content while exchanging data.

  • Patent number: 8712214
    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.
