Abstract: A data recording/playing configuration on a coding process for a recorded 3D image. Attribute information of the 3D image is recorded in each of hierarchized management information files as an attribute in units of management data of each of the management information files. The attribute information to be recorded can include attribute information of a coding process of a 3D image to be recorded. During decoding of the 3D image, inter-image reference identification data indicating whether or not inter-image reference between a left-eye image and a right-eye image is likely to be needed or coding mode identification data indicating whether or not an entropy coding mode is used for coding the 3D image are recorded as attribute information. A playing apparatus can determine a coding mode without performing analysis of data to be played, to correctly perform a decoding process.

Abstract: In processing of recording data on a recording medium, three-dimensional image discrimination data representing whether or not there is a possibility of a three-dimensional image being included in recorded data is recorded as management information. The three-dimensional image discrimination data is recorded in a clip information file set in association with a stream file as a storage file of image data, a playlist file including reproduction section designating information for the clip information file, a disc management file which directly or indirectly designates the playlist file, or the like. A reproducing apparatus can thereby easily determine the presence/absence of a three-dimensional image without performing analysis on reproduction target data.

Abstract: A data reproducing apparatus, which is capable of reproducing stream data according to time stamps without need to have an independent time counting clock. At step S141, it is determined whether a received access unit has a time stamp. When the access unit has a time stamp, the flow advances to step S142. At step S142, a value of the time stamp is set. When the access unit does not have a time stamp. The flow advances to step S144. At step S144, a value corresponding to the previous pic_struct is added to the current time. Thereafter, the flow advances to step S143. At step S143, the current pic_struct is stored for the next process. The present invention is capable of being applied to for example a game device using a DVD.

Abstract: A process corresponding to a reproduction time of data and an argument information is executed. When mark_time_stamp representing one reproduction time on a time axis of a play list, mark_type representing a type of Mark( ), and mark_type are of a type of an event that is generated, if a reproduction time of data reproduced corresponding to a play list containing PlayListMark( ) having Mark( ) including mark_data as an argument of the event matches mark_time_stamp, Mark( ) having mark_time_stamp is recognized at step S302. When mark_type of Mark( ) recognized represents a type in which the event is generated at step S307, mark_data of Mark( ) and occurrence of the event are notified at step S307. A process corresponding to mark_data is executed at step S308. The present invention can be applied to for example a game machine and so forth that use a DVD.

Abstract: For a large capacity recording medium, a user interface having high flexibility and enriched representation is accomplished. A flag that represents whether a play item has a multiple angle structure of which the play item is reproduced with a plurality of angles is described. In addition, a flag that represents whether the beginning of each decode unit is an angle switchable point is described. In a seamless multiple angle structure, the current angle can be switched without need to increase the number of interleave units. In a nonseamless multiple angle structure, with the flag, in a predetermined region on the rear end side of each angle, the current angle is prohibited from being switched. Thus, when a play item exits from the multiple angle, discontinuity in the reproduction can be prevented. In addition, with a flag that represents whether a sub play item should be reproduced not in synchronization with a main path, the sub play item of only audio data can be used as a BGM.

Abstract: A variable speed reproduction is accomplished without sacrifice of picture quality. A controller 425 creates EP_map( ) in a clip information file with an address of RAPI extracted by an RAPI information extraction unit 423, PTS of an intra-picture immediately preceded by RAPI, and one of end positions of the intra-picture and second, third, and fourth reference pictured preceded by the intra-picture and stores EP_map( ) to an output server 426. In other words, the controller 425 copies a value close to a predetermined sector count (the number of sectors that can be read at a time in the encode process) of the end positions of the four reference pictures (1stRef_picture, 2ndRef_picture, 3rdRef_picture, and 4thRef_picture) to N-th_Ref_picture_copy, decides index_minus1 based on N-th_Ref_picture_copy and records it on a disc.

Abstract: The invention provides a recording/reproduction apparatus and method as well as a recording medium wherein, when nondestructive editing is executed for an AV signal, the AV signal can be reproduced seamlessly without suffering from any interruption. Information representative of states (an A type, a C type, a D type, or an E type) of an IN point and an OUT point on a Clip, designated by a Playitem, of a Playlist in which at least more than one Playitems are arranged in the order of reproduction is described in a block Playitem( ).

Abstract: It is possible to display a caption with an aspect ratio independent from the aspect ratio of a main video. When a flag indicating that the aspect ratio of the caption is 16:9 is set, the caption video image frame size (720×480) is converted so as to match the aspect ratio of 16:9 and the caption video obtained as the result is superimposed on the main video and displayed. That is, when the main video has an aspect ratio of 4:3, as shown in FIG. 19, reduction in the lateral direction is performed and the main video is displayed with addition of black tone at the right and left but the caption video is displayed with the aspect ratio of 16:9.

Abstract: To facilitate implementing a user operation control in a picture reproducing apparatus for reproducing contents recorded on a disk or the like. A picture reproducing apparatus selects and reproduces a plurality of prerecorded picture streams in the disk. A reproduction control unit is configured to reproduce the picture streams in either of two reproduction modes, i.e., a normal mode for accepting particular key inputs pertaining to picture reproduction and a menu mode for not accepting the particular key inputs. The mode in which the picture streams are reproduced may be written by contents creators in a script file which is recorded on the disk.

Abstract: For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer. The image data and sound data are stored in a buffer. Image data is read from the buffer in accordance with a scenario and expanded to a graphics plane. In addition, corresponding sound data is read from the buffer and reproduced by a sound player. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.

Abstract: The present invention relates to a playback apparatus, playback method, a storage apparatus, a storage method, a program, a storage medium, a data structure, and a method of producing a storage medium, capable of controlling non-normal playback operations. In a state in which PlayItem_random_access_flag is set to 0 for PlayItem(1) and PlayItem(3) and an Entry Mark is defined in PLayItem(2) for which PlayItem_random_access_flag is set to 1, if a user operation occurs to request a jump to the Entry Mark in PlayItem(2) when a Clip AV stream pointed to by PlayItem(1) is being played back, the playback position jumps not to the Entry Mark in PlayItem(2) but to the beginning of a Clip AV stream pointed to by PlayItem(2). The present invention is applicable to a playback apparatus and a storage apparatus.

Abstract: When the BD-ROM standard is extended to recordable record mediums, a system which stores title numbers when a title is deleted and a system which stores the order of which titles were recorded when a title is deleted and which changes the title numbers are allowed to co-exist. Information title_id_ref that represents a title is added to a play list to which the title belonged when the play list was created. When a disc from which a title was deleted by a recorder A that stores the order of which titles were recorded, but not file numbers is loaded into a recorder B that stores title numbers, the recorder B rewrites the title number of the index based on information title_id_ref. A play list corresponding to a title that was deleted and its number was unused and an object that references the play list are created and a title that calls the object is registered to the index. Thus, the recorder A and the recorder B can have compatibility with respect to editing a title.

Abstract: For a BD-ROM, a picture-in-picture function and a wallpaper display function are accomplished. A second video plane 50 for displaying a moving picture is added to planes 10, 11, and 12 for displaying a moving picture, a subtitle, and graphics, respectively. One of the outputs of the second video plane 50 and the video plane 10 is selected by a switch 51 on a pixel-by-pixel basis. Reduced moving picture data are stored on the second video plane 50. The switch 51 is controlled according to a display position of the reduced moving picture data on a pixel-by-pixel basis. As a result, reduced moving picture data of the second video plane 50 are displayed as a sub screen against the moving picture data of the video plane 10. When wallpaper picture data instead of the moving picture data are stored on the video plane 10, a display screen is obtained as if a wallpaper were displayed in the background of the reduced moving picture data.

Abstract: The present invention relates to a reproducing apparatus and a reproducing method. A code number is inputted. First control information is reproduced in an info file for controlling reproduction of all of a plurality of playlists recorded on a recording medium. Second control information is reproduced in a playlist for controlling reproduction of the playlist. The reproduction of data is permitted, even when the first control information and the second control information are both active, if the inputted code number is consistent with a personal identification number (PIN) which is recorded in the info file, without requiring another input of the code number. Display of information in a playlist is controlled and the display of the information in the playlist is prohibited when the first control information or the second control information is active.
