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.

A record medium is disclosed. The record medium that is readable by a computer device and on which content data that contain at least one of a video stream and an audio stream and at least one resource file that contains a reproduction control program that controls the reproduction of the content data and data used by the reproduction control program are recorded. The file name of the resource file contains information that represents a language that is normally used when the content data are reproduced and information that represents a language attribute of the resource file.

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.

A state transition of a player operation is explicitly defined to facilitate the production of interactive contents. As a player model for reproducing a disk, a model including a player 300 for reproducing a stream, a platform 301 providing an interface between the player 300 and a hardware, and a script player 302 for realizing a scenario intended by a content producer is conceived. The states of the player 300 are defined by four states defined by combinations of two states as to whether the play list reproduction is performed or not and two states as to whether the command 311 is accepted or not. The state transition of the player 300 among the four states is generated by a method 313 from the script layer 302, but not by the player 300 itself or the command 311. The states of the player 300 are small in number, and the conditions for state transition are definite. Therefore, the interactive contents can be easily produced and mounted on devices.
摘要:
When content is reproduced from a disc, audio and a subtitle can be properly and automatically selected. An original language can be set as a language of an audio stream to be reproduced on a player side. An audio stream of the original language is described at a position that comes first in a clip information file. When audio and a subtitle are automatically set, if their languages match, the subtitle is not displayed. When player setting 500 denotes that audio is an original language and subtitle Japanese and streams 501 contained in a disc are an audio stream of Japanese (original language), an audio stream of English, a subtitle stream of English, and a subtitle stream of Japanese, the audio stream of Japanese as the original language and the subtitle stream of Japanese are selected according to the automatic setting. Since their languages match, although streams 502 finally selected are the audio stream of Japanese and the subtitle stream of Japanese, the subtitle stream of Japanese is not displayed.
摘要:
It is possible to realize variable-speed reproduction without deteriorating the image quality. For RAPI from a RAPI information extractor (423), a controller (425) selects one of its address, PTS of the intra-picture immediately after, and the end position of the intra-picture and the second, third, fourth reference image, and creates EP_map( ) in the clip information file, which is accumulated in an output server (426). That is, among the four reference image end positions (1stRef_Picture, 2ndRef_Picture, 3rdRef_Picture, 4thRef_Picture), the controller (425) copies a value near to a predetermined number of sectors (the number of sectors which can be read out at once in the encode processing) in N-th_Ref_picture_copy, decides index_minus1 according to the N̂th_Ref_picture_copy, and records it in a disc.
摘要:
A reproduction apparatus has a player section, a content reproduction section, an interface section. The player section has a read section reading data from the record medium on which the content data containing at least one of a video data stream and an audio data stream and a reproduction control program controlling the reproduction of the content data are recorded, an input section accepting an input from a user, and an output section outputting the reproduced content data. The content reproduction section reproduces the content data according to the reproduction control program. The interface section interfaces among the content reproduction section, the reproduction control program, and the player section. When a command representing an end of the reproduced content data is described in the reproduction control program, the reproduction control program supplies the command to the interface section and the interface section executes a process corresponding to the command.

摘要:
To implement a continue play in a manner intended by contents creators. A reproduction control unit reproduces picture contents prerecorded on a recording medium. A script control unit interprets and executes a script program prerecorded on a recording medium, the script program including an event handler to be executed when an event occurs in the reproduction control unit. A data storage unit has an area for storing backup information on a reproduction status which is information for performing a continue play whereby previously reproduced picture contents are reproduced from a point at which they are left off last time. The script control unit performs a continue play of the picture contents in accordance with the information on the reproduction status in response to the occurrence of the event in the reproduction control unit.
