Claim 4

An apparatus for recording a picture sequence on a disk-shaped recording medium at least on a picture basis, characterized by comprising: a number allocation means for allocating unique numbers to the pictures of the disk-shaped recording medium for one-to-one correspondence; and a file management means for managing a file of editing information apart from the physical addresses of the substantive data on the disk-shaped recording medium; the picture sequence being edited by managing the numbers allocated to the respective pictures for one-to-one correspondence, the file of editing information being recorded on the disk-shaped recording medium, wherein a picture stream subjected to 2 - 3 pull-down processing of converting pictures with a frame frequency of 24 Hz into picture with a field frequency of 60 Hz, said frame frequency is used to manage the unique numbers allocated to said pictures on the basis of 24 Hz.

Claim 5

A method for reproducing a picture sequence recorded on a disk-shaped recording medium at least on a picture by picture basis, characterized by comprising steps of: reading out a file of editing information from the disk-shaped recording medium apart from the physical addresses of the substantive data on the disk-shaped recording medium; and reproducing, at least partly, the pictures having respective unique numbers allocated thereto for one-to-one correspondence and managed by using the file of editing information on the basis of the file of editing information, wherein a picture stream subjected to 2 - 3 pull-down processing of converting pictures with a frame frequency of 24 Hz into pictures with a field frequency of 60 Hz, said frame frequency is used to manage the unique numbers allocated to said pictures on the basis of 24 Hz.

Claim 6

A method for reproducing a picture sequence recorded on a disk-shaped recording medium at least on a picture by picture basis, characterized by comprising steps of: reading out a file of editing information from the disk-shaped recording medium apart from the physical addresses of the substantive data on the disk-shaped recording medium; and reproducing, at least partly, the pictures having respective unique numbers allocated thereto for one-to-one correspondence and managed by using the file of editing information on the basis of the file of editing information, wherein a picture stream subjected to 2 - 3 pull-down processing of converting pictures with a frame frequency of 24 Hz into pictures with a field frequency of 60 Hz, said frame frequency is used to manage the unique numbers allocated to said pictures on the basis of 24 Hz.

Claim 7

A method for reproducing a picture sequence recorded on a disk-shaped recording medium at least on a picture by picture basis, characterized by comprising: a file reading means for reading out a file of editing information from the disk-shaped recording medium apart from the physical addresses of the substantive data on the disk-shaped recording medium; and a reproduction control means for reproducing, at least partly, the pictures having respective unique numbers allocated thereto for one-to-one correspondence and managed by using the file of editing information on the basis of the file of editing information, wherein a picture stream subjected to 2 - 3 pull-down processing of converting pictures with a frame frequency of 24 Hz Into pictures with a field frequency of 60 Hz, said frame frequency is used to manage the unique numbers allocated to said pictures on the basis of 24 Hz.

Claim 8

A method for reproducing a picture sequence recorded on a disk-shaped recording medium at least on a picture by picture basis, characterized by comprising: a file reading means for reading out a file of editing information from the disk-shaped recording medium apart from the physical addresses of the substantive data on the disk-shaped recording medium; and a reproduction control means for reproducing, at least partly, the pictures having respective unique numbers allocated thereto for one-to-one correspondence and managed by using the file of editing information on the basis of the file of editing information, wherein a picture stream subjected to 2 - 3 pull-down processing of converting pictures with a frame frequency of 24 Hz Into pictures with a field frequency of 60 Hz, said frame frequency is used to manage the unique numbers allocated to said pictures on the basis of 24 Hz.
