Abstract

A reproduction apparatus is designed to select and decode speech and subtitles (characters) in a given language from a disk on which various types of information are recorded in different languages. This system arrangement makes it possible to standardize the manufacture of disks and reproduction apparatuses world-wide, resulting in a reduction in production cost. In a disk 100, various types of information are recorded in different languages along with video information. A reproduction apparatus selects information in a given language from the reproduced information using a data string processing section 203, a system control section 204, and an operator section 205, and supplies the selected pieces of information to each of a video processing section 206, a subtitle decoder 211, and an audio processing section 213.

Claims

1. A reproduction apparatus for reproducing information from a disk in which a management area is formed in one area of the disk and a data area is formed in another area of the disk, said management area containing information representing a data arrangement of said data area, said data area having a plurality of data units recorded therein with each data unit containing a group consisting of data unit sub-code information, video information, at least two pieces of sub-picture information to be combined or assigned to the video information, and at least two pieces of audio information with each piece of audio information relating to the video information by being arranged in a direction of reading from the disk, said data unit sub-code information within each particular data unit containing control information items corresponding to that particular data unit, at least one of said management area and said data area containing reproducible first and second user selective menu information items, said reproduction apparatus comprising:

means for reading information of said management area and said data area from said disk, said means for reading adapted to read any of said data unit sub-code information, said video information, said sub-picture information, and said audio information from said data area and adapted to read any of said first user selective menu information item and said second user selective menu information item from at least one of said management area and said data area;

a first means for providing a first menu representing said first user selective menu information item; and

a second means for providing a second menu representing said second user selective menu item,

wherein said second user selective menu information item is reproducible in accordance with a selection of said first user selective menu information item, and

wherein at least one of said first and second user selective menus include a still picture.

2. The reproduction apparatus of claim 1, wherein said second user selective menu information item includes at least one of said audio information pieces and said sub-picture information pieces, and

wherein at least one of said audio and sub-picture information pieces is reproducible in accordance with a selection of the second user selective menu information item.

3. The reproduction apparatus of claim 1, wherein said management area includes predetermined content codes, representing respective contents of said pieces of said audio and said sub-picture information.

4. The reproduction apparatus of claim 1, wherein each of said audio information pieces comprises a plurality of frames, each of said plurality of frames being formed of consecutive pairs of a header and an associated set of data, and

wherein each of said header contains time information on the associated set of data.

5. The reproduction apparatus of claim 4, wherein in said audio information pieces, a period of silence is recorded in that said header, representing the period of silence, is immediately followed by the header of the next pair and no set of data is recorded for silence.

6. The reproduction apparatus of claim 1, wherein up to eight pieces of said audio information are provided in each of said data units, and each piece thereof contains a different language.

7. The reproduction apparatus of claim 1, wherein each said video information, each piece of said sub-picture information related to said video information, and each portion of said audio information related to said video information of one group correspond to a same period of time of recording or reproducing.

8. The reproduction apparatus of claim 1, wherein said video information of each said data unit is formed from a plurality of consecutive frames.
