Method and apparatus for editing a program on an optical disc

A method for editing an audio/video program on a re-writable optical disc, the method comprising the steps of:

• audio/video program editing apparatus acquiring description information of two program segments of said audio/video program from a rewritable optical disc, said two program segments being in sequence in a play-back order, said description information comprising ending point information of a previous program segment and start point information of a subsequent program segment;
• the apparatus determining start point information and end point information of a program segment to be played with respect to ending point information of the previous program segment and the start point information of the subsequent program segment, wherein said program segment to be played start point information is transformed as being one of:
• up to said previously program segment end point information;
• and said subsequent program segment start point information, and said program segment to be played end point information is transformed as being one of:
• said previous segment end point information;
• and at least said subsequent segment start point information;
• the apparatus generating a guiding information to guide the ending point information of the previous program segment to the start point information of the subsequent program segment according to the description information and play-back order of said program segments with regard to the start point information and the end point information of the program segment to be played;
• and
• the apparatus updating the description information of said program according to said guiding information;
• and
• the apparatus storing the updated description information of said audio/video program to said disc.
