Abstract:
1. A recording and reproducing apparatus for recording a video signal on an optical disc using a video recording (VR) format and for reproducing the optical disc in which the video signal is recorded in the VR format, comprising: an extension information recording means for generating extension information including character string information representing an input character string and correspondence information representing an object to which the character string corresponds, and for recording the extension information on the optical disc; and an extension information display means for displaying the extension information read from the optical disc, wherein a program and a cell in the optical disc main body and an original program chain, and a program and a cell in a user-defined program chain are included in the object to be corresponded by means of the correspondence information, the correspondence information includes third information, first information representing a program number in the original program chain or a program chain number in the user-defined program chain, and second information representing a cell number, when the third information represents the optical disc itself, the character string corresponds to the optical disc itself, when the third information represents the original program chain or the user-defined program chain and when the second information has a value other than zero, the character string represents a corresponding cell within a corresponding program or a corresponding cell within a corresponding program chain, when the third information represents the original program chain or the user-defined program chain and when the second information has a value of zero, the character string corresponds to the corresponding program or the corresponding program chain, an area where the extension information is recorded by the extension information recording means is a predetermined area within a data area, and an area where the extension information is recorded is represented as an empty area in volume/file structure information representing a usage state of the data area, and when reproduction is indicated at a state when the object corresponded to the character string of the extension information displayed by an extension information display means is indicated by the cursor, the object indicated by a cursor is reproduced.
