Abstract

The present invention provides a method and apparatus for editing an audio/video program. The method comprises the steps of acquiring the description information of two program segments of the program, the program segments being in sequence in playing-back order, the description information comprising the ending description information of the previous program segment and the start point information of the subsequent program segment, generating a guiding information to guide the ending point information to the start point information according to the description information and playing-back order of the program segments and updating the description information of the program according to the guiding information. With this invention, excessively detailed application editing work and an expense of high buffering cost may be avoided in editing compact disc program.

First claim

What is claimed is:

1 . An audio/video program editing apparatus for editing an audio/video program, comprising:
an editing device editing an audio/program into a first program segment and a second program segment, the second program being subsequent to and non-contiguous with the first program segment, wherein the first program segment and the second program segment have a start point and an end point; an acquiring device acquiring:
the end point information of the first program segment and the start point information of the second program segment;
a generating device generating:
guiding information between the end point information of the first program segment and the start point information of the second program segment, the guiding information representing a bridge between the non-contiguous first and second program segment; and

an updating device updating:
a descriptive information associated with the audio/video program with the generated guiding information; and
providing an indication of the updated descriptive information.

2 . The editing apparatus of claim 1 , wherein the audio/visual program is stored on a writable storage medium.

3 . The editing apparatus of claim 2 , wherein the start point and the end point of the programs segments is one of: a time and an address.

4 . The editing apparatus of claim 1 , wherein the guiding information represents a sequential connection relationship between respective ones of the two program segments.

5 . The editing apparatus of claim 1 , further comprising:
a playback apparatus playing the audio/video program based on the descriptive information of the audio/video program, the playback apparatus determining a presence of the indication of the descriptive information being updated.

6 . The editing apparatus of claim 1 , wherein the updated descriptive information represents a sequential connection relationship between respective ones of the first program segment and the second program segment.

7 . The editing apparatus of claim 1 , further comprising:
playing, by the application, the audio/visual program from a start point of the audio/visual program to an end point of the audio/visual program.

8 . The editing apparatus of claim 1 , wherein the indication is one of: real and virtual.

9 . The editing apparatus of claim 8 , wherein the virtual indication, indicates at least one guiding information associated with corresponding pairs of first and second program segments.

10 . A playback device for playing an audio/video program, the playback device comprising:
a processor:
accessing descriptive information of an audio/video program;
determining whether an indication of an update of the descriptive information of the audio/video program is available, wherein the updated descriptive information includes guiding information that represents an end point of a first program segment of the audio/video program and a start point of a second program segment of the audio/video program;
playing the audio/video program, when the indication of updated descriptive information is available, wherein playing the audio/video program comprises accessing the guiding information for playing the audio/video program until the end point of the first program segment and transitioning to the start point of the second program segment.

11 . The playback device of claim 10 , wherein the audio/video program is stored on a rewritable medium.

12 . The playback device of claim 10 , further comprising:
executing an application for playing the audio/visual program in accordance with the description information.

13 . A method for operating an audio/video program playback apparatus, the method comprising:
in an audio/video program playback apparatus: accessing descriptive information associated with the audio/video program; accessing an application for the playback of the audio/video program; determining whether an indication of updated descriptive information is available; playing, by the application, the audio/video program based on the updated descriptive information, wherein the update descriptive information includes an end point of a first program segment and a start point of a second program, wherein the application plays the audio/video program up to the end point of the first program segment and transitions to the start point of the second program segment.

14 . A computer-readable storage-medium that is not a transitory propagating signal or wave, the medium modified by control information including instructions for performing a method, for operating an audio/video program playback apparatus, the method comprising:
in an audio/video program playback apparatus: accessing descriptive information associated with the audio/video program; accessing an application for the playback of the audio/video program; determining whether an indication of updated descriptive information is available; playing, by the application, the audio/video program based on the updated descriptive information, wherein the update descriptive information includes an end point of a first program segment and a start point of a second program, wherein the application plays the audio/video program up to the end point of the first program segment and transitions to the start point of the second program segment.
