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 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: 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: 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.
