Abstract

A multi-scene recording disk and a data reproducing apparatus, which enable a user to select and enjoy one of simultaneously proceeding scenes, and also enable a program editor to edit programs using a new concept and novel fashion. Related program movements, each consisting of program bars, are recorded on the disk 100. The data reproducing apparatus includes a data string processing section 203, a system control section 204, an operator panel 205, a video processing section 206, and audio processing sections 211 and 213. The sections 203 and 204 and the panel 205 select any one of the program movements, and switch one movement to another, and select any one of the program bars of the movement selected and switch one bar to another. The information thus selected is supplied to the video processing section 206 and the audio processing sections 211 and 213.

2. An apparatus according to claim 1, wherein said second and fourth program information items each contain a relative address recorded at a start of the respective program information item, said second and fourth program information items being connected when said relative address coincide.

3. 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 represent 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:

reading information from said disk and generating pickup signals based on said information;

generating multi-scene configuration data by demodulating said pickup signals, said multi-scene configuration data being based on said multi-scene configuration information recorded in said management area of said disk;

storing the multi-scene configuration data; and

freezing an image of a first data unit that is being decoded when scene-switching data is input while one of said second and fourth program information items is being reproduced from said disk, selecting a target program information item from among said second and fourth program information items based on said scene switching data, switching to a head portion of said target program information item, and decoding a second data unit of said target program information item that corresponds to said first data unit.
