Data recording medium having reproduction timing information, and system for reproducing record data by using the reproduction timing information

A recording method for a recording medium, comprising the steps of:

• recording video data to be reproduced as a moving picture;
• recording first audio data to be reproduced along with said video data, said first audio data being in a first language;
• recording first sub-picture data which can be presented along with said first audio data and which can be selectively set in one of a presentation mode and a non-presentation mode in association with said first audio data, said first sub-picture data presenting sub-picture information in said first language;
• and
• recording control information for forcibly presenting without user's intervention said first sub-picture data in a predetermined time slot of a reproduction time sequence during which said first audio data is reproduced, even if said first sub-picture data is set in said non-presentation mode so that said first sub-picture information is presented without using additional sub-picture data associated with said first language duplicating said first sub-picture data.

A recording apparatus for recording medium, comprising:

• means for recording video data to be reproduced as a moving picture;
• means for recording first audio data to be reproduced along with said video data, said first audio data being in a first language;
• means for recording first sub-picture data which can be presented along with said first audio data and which can be selectively set in one of a presentation mode and a non-presentation mode in association with said first audio data, said first sub-picture data presenting sub-picture information in said first language;
• and
• means for recording control information for forcibly presenting without user's intervention said first sub-picture data in a predetermined time slot of a reproduction time sequence during which said first audio data is reproduced, even if said first sub-picture data is set in said non-presentation mode so that said first sub-picture information is presented without using additional sub-picture data associated with said first language duplicating said first picture data.

A reproducing apparatus for a recording medium which comprises video data to be reproduced as a moving picture, first audio data to be reproduced along with said video data, said first audio data being in a first language, first sub-picture data which can be presented along with said first audio data and can be selectively set in one of a presentation mode and a non-presentation mode in association with said first audio data, said first sub-picture data presenting sub-picture information in said first language, and control information concerning presentation of said first sub-picture data, comprising:

• reproducing means for reproducing said video data, said first audio data and said first sub-picture data from said recording medium;
• selection means for selecting one of said presentation mode and said non-presentation mode of said sub-picture data in said reproducing means;
• and
• control means for forcibly presenting without user's intervention said first sub-picture data in a predetermined time slot of a reproduction time sequence during which said first audio data is reproduced, even if said first sub-picture data is set in said non-presentation mode based on said control information so that said first sub-picture information is presented without using additional sub-picture data associated with said first language duplicating said first sub-picture data.

A reproducing method for a recording medium which comprises video data to be reproduced as a moving picture, first audio data to be reproduced along with said video data, said first audio data being in a first language, first sub-picture data which can be presented along with said first audio data and can be selectively set in one of a presentation mode and a non-presentation mode in association with said first audio data, said first sub-picture data presenting sub-picture information in said first language, and control information concerning presentation of said first sub-picture data, comprising:

• a reproducing step of reproducing said video data, said first audio data and said first sub-picture data from said recording medium;
• a selecting step of selecting one of said presentation mode and said non-presentation mode of said sub-picture data in said reproducing step;
• and
• a control step of forcibly presenting without user's intervention said first sub-picture data in a predetermined time slot of a reproduction time sequence during which said first audio data is reproduced, even if said first sub-picture data is set in said non-presentation mode based on said control information so that said first sub-picture information is presented without using additional sub-picture data associated with said first language duplicating said first sub-picture data.
