Claims
- 1. An apparatus for reproducing information from a multi-scene recording medium including a disk having a management area and a data area, said data area recording a first program information item, a second program information item following said first program information item, a third program information item following said second program information item, and a fourth program information item for replacing said second program information item, wherein said second and fourth program information items include simultaneously proceeding scenes, said management area recording multi-scene configuration information indicating that second and fourth program information items are linked to each other, data units of said second program information item and data units of said fourth program information item being alternatingly and continuously recorded on said recording medium, said apparatus comprising:
- pickup means for generating signals based on information recorded on said disk;
- demodulation means for generating multi-scene configuration data by demodulating signals generated by said pickup means, said multi-scene configuration data being based on said multi-scene configuration information recorded in said management area of said disk;
- management data storage means for storing said multi-scene configuration data generated by said demodulation means;
- menu generating means for generating, based on a decoded output, a menu displaying an image relating to said program information item being decoded when said multi-scene configuration data indicates that said second or fourth program information item is being reproduced, said menu being used to switch between reproduction of said second program information item and said fourth program information item, where
- when reproduction is to be switched from one of the second and fourth program information items to another of the second and fourth program information items while the one program information item is being reproduced, reproduction of the other program information item starts from a head portion of a data unit of the other program information item.
- 2. A method of reproducing information from a multi-scene recording medium including a disk having a management area and a data area, said data area recording a first program information item, a second program information item following said first program information item, a third program information item following said second program information item, and a fourth program information item for replacing said second program information item, wherein said second and fourth program information items include simultaneously proceeding scenes, said management area recording multi-scene configuration information indicating that said second and fourth program information items are linked to each other, data units of said second program information item and data units of said fourth program information item being alternatingly and continuously recorded on said recording medium, said method comprising the steps of:
- reading information from said disk and generating pickup signals based on said information;
- generating multi-scene configuration data by demodulating said pickup signals;
- storing said multi-scene configuration data; and
- generating a menu by combining an image corresponding to a program information item which is being reproduced with a decoded output of said program information item which is being reproduced, when said multi-scene configuration data indicates that said second or fourth program information item is being reproduced, said menu being used to switch between reproduction of said second program information item and said fourth program information item, where
- when reproduction is to be switched from one of the second and fourth program information items to another of the second and fourth program information items while the one program information item is being reproduced, reproduction of the other program information item starts from a head portion of a data unit of the other program information item.
- 3. An apparatus for reproducing information from a multi-scene recording medium including a disk having a management area and a data area, said data area recording a first program information item, a second program information item following said first program information item, a third program information item following said second program information item, and a fourth program information item for replacing said second program information item, wherein said second and fourth program information items include simultaneously proceeding scenes, said management area recording multi-scene configuration information indicating that second and fourth program information items are linked to each other, data units of said second program information item and data units of said fourth program information item being alternatingly and continuously recorded on said recording medium, said apparatus comprising:
- pickup means for generating signals based on information recorded on said disk;
- demodulation means for generating multi-scene configuration data by demodulating signals generated by said pickup means, said multi-scene configuration data being based on said multi-scene configuration information recorded in said management area of said disk;
- management data storage means for storing said multi-scene configuration data generated by said demodulation means;
- menu generating means for generating, based on a decoded output, a menu displaying an image relating to said program information item being decoded when said multi-scene configuration data indicates that said second or fourth program information item is being reproduced, said menu being used to switch between reproduction of said second program information item and said fourth program information item, where
- when reproduction is to be switched from one of the second and fourth program information items to another of the second and fourth program information items while the one program information item is being produced, reproduction of the other program information item starts from a head portion of a data unit of a program information item next to the other program information item.
- 4. A method of reproducing information from a multi-scene recording medium including a disk having a management area and a data area, said data area recording a first program information item, a second program information item following said first program information item, a third program information item following said second program information item, and a fourth program information item for replacing said second program information item, wherein said second and fourth program information items include simultaneously proceeding scenes, said management area recording multi-scene configuration information indicating that said second and fourth program information items are linked to each other, data units of said second program information item and data units of said fourth program information item being alternatingly and continuously recorded on said recording medium, said method comprising the steps of:
- reading information from said disk and generating pickup signals based on said information;
- generating multi-scene configuration data by demodulating said pickup signals;
- storing said multi-scene configuration data; and
- generating a menu by combining an image corresponding to a program information item which is being reproduced with a decoded output of said program information item which is being reproduced, when said multi-scene configuration data indicates that said second or fourth program information item is being reproduced, said menu being used to switch between reproduction of said second program information item and said fourth program information item, where
- when reproduction is to be switched from one of the second and fourth program information items to another of the second and fourth program information items while the one program information item is being reproduced, reproduction of the other program information item starts from a head portion of a data unit of a program information item next to the other program information item.
- 5. The apparatus according to claim 1, wherein each of said first, second, third and fourth program information items includes video data.
- 6. The method according to claim 2, wherein each of said first, second, third and fourth program information items includes video data.
- 7. The apparatus according to claim 3, wherein each of said first, second, third and fourth program information items includes video data.
- 8. The method according to claim 4, wherein each of said first, second, third and fourth program information items includes video data.
