Abstract

A system for playing a digest of a moving image file is provided, including: a header parsing part that parses a header of the moving image file and acquires information concerning the playback length M and random access point of the moving image file; a section dividing part that divides the playback length M by the number N of equal sections and determines a starting point S(i) of each of the sections; a correction part that corrects the starting point S(i) to a closest random access point R(i) of the moving image file; and a digest playback part that determines a playback segment P(i) of each of the sections which corresponds to a distance extended from the closest random access point R(i) by a playback length L, and sequentially plays the playback segments P(i).

Claims (22)

1. A system for playing a digest of a moving image file, comprising:

a header parsing part that parses a header of the moving image file and acquires information concerning the playback length M and random access point of the moving image file;

a section dividing part that divides the playback length M by the number N of equal sections and determines a starting point S(i) of each of the sections;

a correction part that corrects the starting point S(i) to a closest random access point R(i) of the moving image file; and

a digest playback part that determines a playback segment P(i) of each of the sections which corresponds to a distance extended from the closest random access point R(i) by a playback length L, and sequentially plays the playback segments P(i).

2. The system of claim 1 , wherein the digest playback part further inserts and plays a boundary image between playback segments P(i) of two adjacent sections to inform a user that the digest of the moving image file is not continuously played.

3. The system of claim 2 , wherein the boundary image is an image having a fade-in and/or fade-out effect.

4. The system of claim 2 , wherein the boundary image is an image having a sound effect (volume-up and/or volume-down).

5. The system of claim 3 , wherein the boundary image is an image having a sound effect (volume-up and/or volume-down).

6. The system of claim 1 , wherein the moving image file is encoded in MPEG (Moving Picture Experts Group) format.

7. The system of claim 2 , wherein the moving image file is encoded in MPEG format.

8. The system of claim 3 , wherein the moving image file is encoded in MPEG format.

9. The system of claim 6 , wherein the random access point is a position of I-frame (Intra-coded frame) coded independently of all other frames.

10. The system of claim 7 , wherein the random access point is a position of I-frame coded independently of all other frames.

11. The system of claim 8 , wherein the random access point is a position of I-frame coded independently of all other frames.

12. The system of claim 1 , further including a setup part that sets the number N of the sections and the playback length L.

13. The system of claim 2 , further including a setup part that sets the number N of the sections and the playback length L.

14. The system of claim 3 , further including a setup part that sets the number N of the sections and the playback length L.

15. The system of claim 12 , wherein the playback length L is shorter than a length obtained by dividing the playback length M of the moving image file by the number N of sections.

16. The system of claim 13 , wherein the playback length L is shorter than a length obtained by dividing the playback length M of the moving image file by the number N of sections.

17. The system of claim 14 , wherein the playback length L is shorter than a length obtained by dividing the playback length M of the moving image file by the number N of sections.

18. A mobile communication terminal equipped with the system of claim 1 .
