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.

Abstract: A video information playback method of playing back a recording medium on which a virtual-machine-using content whose video playback can be controlled by a program running in a virtual machine is recorded, including: performing simple resume playback for restarting playback of a main-program video of the virtual-machine-using content without activating the program, when the playback of the main-program video is interrupted and then a playback restart instruction is given; and skipping playback of predetermined video which is to be played back until a menu screen is displayed, when the simple resume playback of the main-program video is finished and then playback from an initial state is performed with activating the program.

Abstract: The amount of data stored in a video buffer (3) that temporarily stores multi-angle streams (A, B) is controlled from information giving the distance between the angle blocks (A—1, B—1, A—2, B—2, . . . ) of the multi-angle streams and an audio stream (C) on a recording medium (10). In multi-angle playback, in which multiple files are read simultaneously, this can shorten the time from when the user switches the angle until the image reproduced by a video display apparatus changes to the intended angle.

Abstract: A video information player device (100) comprises: a video decoder (126) which decodes content data of content and generates a video signal and a vertical synchronization signal; a synchronization frame processing unit (128) which detects the vertical synchronization signal and generates a synchronization frame triggered by the detection of the vertical synchronization signal; an Ethernet controller (121) which transmits the synchronization frame to another video information player device; and a synchronized output unit (127) which outputs the video signal in synchronization with the vertical synchronization signal. If the Ethernet controller (121) is generating an Ethernet frame when the vertical synchronization signal is detected, the synchronization frame processing unit (128) generates the synchronization frame in parallel with the generation of the Ethernet frame.

Abstract: Provided is a video information playback method of reducing a wait time until playback is resumed when resume playback of a content whose video playback can be controlled by a program operating in a virtual machine. After playback of the content is stopped in the resume playback, the program operating in the virtual machine determines whether or not the content to be playback-resumed is a content whose playback is possible either when the program operating in the virtual machine is activated or deactivated. The information of the determining indicating whether the playback is enabled or disabled is recorded in a nonvolatile memory. When a playback resume instruction is inputted, the information of the determining related to the content to be playback-resumed is read out. When the content is determined to be playback-enabled, playback is resumed from the playback stop position without activating the program operating in the virtual machine.

Abstract: An information recording apparatus for recording additional content on a medium on which a title including one or more files is already recorded, includes means for designating a title to be added on the medium; means for transmitting disc package information, the disc package information and unique IDs; means for receiving and additionally recording on the medium the title to be added generated in the content server, file names of files so as not to be the same as the file names of the files constituting the titles already recorded on the medium; means for receiving and additionally recording a new title for display of a menu screen on the medium, which is generated in the content server, so that the title to be added can be selected, on the basis of the disc package information; and means for receiving and additionally recording new disc package information on the medium.

Abstract: Disclosed are an image generating apparatus and an image generating method with which the size of a storage region required to display animated images can be suppressed. In the image generating apparatus (1), processing blocks (12, 16, 17) configuring an image generation unit obtain object data segment (130p) and a display operation pattern to be applied to the object data segment (130p) from data storage units (13, 14), in accordance with a specified picture-plane configuration information item (150i) , and generate animated images of the object data segment (130p) in accordance with the object data segment (130p) and the display operation pattern.

Abstract: A plurality of I- or P-pictures for displaying video images with the same data as the last frame of the main data of the content are added as reproduction synchronization adjustment frames after the last frame of the main data; when reproduction leads a reference reproducing device, more synchronization adjustment frames are reproduced (ST11); when reproduction lags, fewer synchronization adjustment frames are reproduced (ST9). Reproduction can be synchronized among a plurality of reproducing devices (42) that read data from a storage medium and reproduce the data, or receive data by network delivery and reproduce the data, under conditions where system clock correction by use of PCR is impossible.

Abstract: A portable recording medium (100) stores video contents and icon information relating to an icon picture associated with the video contents and indicative of an operation mode corresponding to user operation of the recording medium reproducing apparatus (1). The recording medium reproducing apparatus (1) includes an image display plane (8) which is a frame memory area used for displaying video data of the video contents stored in the portable recording medium (100); a memory (15, 16) which stores the icon information stored in the portable recording medium (100); an OSD plane (18) which is a frame memory area used for displaying the icon picture on the basis of the icon information stored in the memory (15, 16); and a synthesizing device (10) which synthesizes the data held in the video display plane (8) and the data held in the information display plane (18), thereby outputting a superimposed video signal.

Abstract: In a recording medium on which is recorded a multiplexed stream (231) 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.
