摘要:
In order to produce a multiversion cinema application such that selective reproduction of a part of pictures is possible, it is necessary to produce system streams of interleave structure dependent on preceding and succeeding system streams. Once the order of reproduction is determined, it can not be changed during the reproduction. Then, correction in accordance with the restrictions on the video objects depending upon the reproduction order is applied to voice data whose relations with the video objects are shown. Thus, the time required to complete the cinema application by repeating change and deletion of part of pictures can be shortened and the production of a multiversion cinema application can be realized for a producer.

A multimedia optical disk contains a data area for recording a plurality of objects. The data area is composed of a plurality of small areas and one object is recorded over continuous small areas and each small area contains first and second subareas. Animation data in a unit of a prescribed period of time and auxiliary video data to be reproduced simultaneously with the animation data are recorded in the first subarea and the auxiliary video data are a menu picture containing a plurality of buttons used for choosing between various display modes. Control information is recorded in the second subarea and the control information contains button control data required for responding to the operation of the user when the menu picture in the first subarea in the same small area is to be reproduced and supplementary control data for operating the menu for the user. When the optical disk is constituted in such a way, the response and the interactive feature of the disk can be improved, because the disk can be controlled on a small area basis. In addition, since the operation of the user can be executed by using the supplementary control data for each small area, the interactive reproduction advancing performance can be improved.
摘要:
A multimedia optical disk on which a plurality of objects including motion video data, audio data and sub-video data are recorded. Each of the objects is recorded over continuous small areas, and each small area (VOBU#400-VOBU#500 in the Figure) comprises a first sub-area for motion video data, a plurality of second sub-areas for audio data different from each other, a plurality of third sub-areas for sub-video data different from each other, and a fourth sub-area for management information for indicating to a reproducing apparatus a combination of audio data and sub-video data to be reproduced. This arrangement makes it possible to dynamically switch the reproduced outputs of audio data and sub-video data even during reproduction.
摘要:
A multimedia optical disk that has data areas where video data are recorded and management information areas where a channel table in which a logical channel number and a physical channel number of sub-data are correlated with each other is recorded. The video data include time-varying image data and sub-data of a plurality of channels to be selectively reproduced together with the time-varying image data are recorded in an interleaving way. The sub-data is voice data or sub-video data. The logical channel number is a channel number allocated in common to the video data. The physical channel is a channel number used for physically identifying sub-data on the optical disk. This configuration allows sub-data to be systematically managed for the video data. For example, sub-data can be continuously reproduced for video data by, for example, avoiding designating the sub-data in a physical channel in no existence.

A multimedia optical disk capable of developing scenes with full unexpectedness on the basis of interactive control. In this multimedia optical disk, an area for storing chain control information for instructing navigation control on chain reproduction to a reproduction apparatus corresponds to an area for storing a series of addresses representing the reproduction sequence of objects. The objects comprise dynamic image data in a predetermined time unit and sound data as well as sub-image data to be simultaneously reproduced with the dynamic image data, and is recorded in one small area (first sub-area) within the data area. Sub-control information which is the information for instructing the navigation control of an object reproduction to the reproduction apparatus and which is effective for data reproducing within the same small area is recorded in another small area (second sub-area).

摘要:
A multimedia optical disk for easily realizing both alternative reproduction control in a parental lock section and interactive reproduction control. The optical disk has a video data storing area and a management information storing area. In the video data storing area, video data (the figure: PGC#1-#7) in which moving picture data, sound data, subsidiary video data, control information for specifying one item of video data as a branch destination in accordance with the interactive operation on the reproducing device side are interleaved. In the management information storing area, group information including group information representing the alternatively reproduced video data of the same group, the level ID of the video data, and branch information for specifying video data to be reproduced next are recorded. When the branch destination belongs to a group, the control information commands the reproducing device that an abitrary one of the video data in the group is the branch destination. Thus, both the alternative production control such as the parental lock, and interactive reproduction control are performed.
