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.

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 recording and reproducing apparatus for recording a program including video and/or audio information on a removable recording medium includes an interface, a recording unit, a reproducing unit, and a controller. The interface is configured to receive reservation information for recording the selected program. The reservation information includes maximum bit rate information. The recording unit is configured to record the reservation information on the removable recording medium. The reproducing unit is configured to reproduce the reservation in formation from the recording medium when the removable recording medium is loaded. The controller is configured to record the selected program on the removable recording medium based on the reservation information.

When the user enters a command to eject an optical disc from an optical-disc apparatus by operating an input unit, a CPU records information such as an operating mode and a location accessed immediately prior to ejection of the disc into a RAM unit as resume-function related information. The resume-function related information is then supplied to the optical disc to be recorded thereon by way of a write-in channel buffer, a switch, an ECC circuit, an RF & demodulation/modulation circuit and an optical head. Accordingly it is possible to make an access to a location on an optical disc accessed immediately prior to ejection of the disc from an optical-disc apparatus when the disc is reinserted into the optical-disc apparatus.

With append_only_flag reset to 0, data is recorded over existing data on a disc in accordance with the value of volume_write_protect_level. With append_only_flag set to 1, on the other hand, data can not be recorded over existing data on the disc but can be appended to already recorded data in a range defined by the value of volume_write_protect_level. As a result, it is possible to prevent new data from being written over already recorded data by mistake and to utilize the recording area of the disc efficiently.

This invention provides a recording apparatus, a recording method, a playback apparatus, a playback method, a recording/playback apparatus, a recording/playback method, a recording medium and a presentation medium. In this invention, information on the album is recorded only into a chief disc, one of the discs composing the album. The other discs simply include an identification of the chief disc. Accordingly it is possible to allow a plurality of recording media to be handled as a unit with ease and to allow each of the recording media to pertain to a plurality of such units.

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.

The present invention relates to a data processing device and a data processing method, a program and a program recording medium, and a data recording medium and a data structure, capable of controlling output of data according to the playing point-in-time of the data. A Clip( ), which is meta data relating to a program stream upon which one or more elementary streams have been multiplexed, includes sets of pts_change_point representing the playing point-in-time of the elementary stream and DynamicInfo( ) including output attributes of the data thereof, for each elementary stream multiplexed on the program stream. In step S321, determination is made regarding whether or not the playing point-in-time of the elementary stream being played matches the pts_change_point, and in the event that determination is made that this matches, in step S322 the DynamicInfo( ) which is a set with the pts_change_point is recognized. Then in step S324, output of the data being played is controlled according to the output attributes included in the DynamicInfo( ). The present invention can be applied to game apparatuses using DVDs, for example.
