Abstract

The invention relates to a substitution method for replacing, in an audiovisual content, a part of the content defined by a time range with an audiovisual substitution sequence, the method being characterized in that the substitution sequence is representative of the part to be replaced. The invention also concerns a device and a terminal implementing the invention.

First claim

1 . Substitution method for replacing, in an audiovisual content, a part of the content defined by a time range with an audiovisual substitution sequence, the method being characterized in that the substitution sequence is representative of the substituted part of said content.

2 . Method according to claim 1 , characterized in that the substitution sequence is generated from a semantic analysis of the part of the content defined by the time range.

3 . Method according to claim 1 , characterized in that the substituted part is stored and in that the substitution sequence comprises an interactive link suitable for triggering the restitution of the substituted part.

4 . Method according to claim 1 , characterized in that the audiovisual content resulting from the substitution contains an index indicating the start of the substitution sequence.

5 . Method according to claim 1 , characterized in that the start and end instants of the time range are determined by the detection of a first and a second particular event in the audiovisual stream.

6 . Method according to claim 5 , characterized in that at least one of the first and second particular events is identified by the recognition of at least one keyword in an audio component of the audiovisual content.

7 . Method according to claim 5 , characterized in that at least one of the first and second particular events is identified by a change of speaker in an audio component of the audiovisual content.

8 . Method according to claim 5 , characterized in that at least one of the first and second particular events is identified by a change of audio source in an audio component of the audiovisual content.

9 . Method according to claim 5 , characterized in that at least one of the first and second particular events is identified by image analysis in a video component of the audiovisual content.

10 . Method according to claim 1 , characterized in that the substitution sequence is representative of the substituted sequence in that it contains a summary of the substituted part.

11 . Substitution device for replacing, in an audiovisual content, a part of the content defined by a time range with an audiovisual substitution sequence, the device including a processing unit suitable for generating a substitution sequence representative of the substituted part of said content.

12 . (canceled)

13 . Computer program containing instructions for execution of a substitution method, when the program is executed by a processor, the substitution method for replacing, in an audiovisual content, a part of the content defined by a time range with an audiovisual substitution sequence, the method being characterized in that the substitution sequence is representative of the substituted part of said content.

14 . Information medium readable by a processor on which there is recorded a computer program comprising instructions for execution of the steps of a substitution method for replacing, in an audiovisual content, a part of the content defined by a time range with an audiovisual substitution sequence, the method being characterized in that the substitution sequence is representative of the substituted part of said content.

15 . The computer program according to claim 13 , characterized in that the substitution sequence is generated from a semantic analysis of the part of the content defined by the time range.

16 . The computer program according to claim 13 , characterized in that the substituted part is stored and in that the substitution sequence comprises an interactive link suitable for triggering the restitution of the substituted part.

17 . The computer program according to claim 13 , characterized in that the audiovisual content resulting from the substitution contains an index indicating the start of the substitution sequence.

18 . The computer program according to claim 13 , characterized in that the start and end instants of the time range are determined by the detection of a first and a second particular event in the audiovisual stream.

19 . The computer program according to claim 18 , characterized in that at least one of the first and second particular events is identified by the recognition of at least one keyword in an audio component of the audiovisual content.

20 . The computer program according to claim 18 , characterized in that at least one of the first and second particular events is identified by a change of speaker in an audio component of the audiovisual content.

21 . The computer program according to claim 18 , characterized in that at least one of the first and second particular events is identified by a change of audio source in an audio component of the audiovisual content.

22 . The computer program according to claim 18 , characterized in that at least one of the first and second particular events is identified by image analysis in a video component of the audiovisual content.

23 . The computer program according to claim 13 , characterized in that the substitution sequence is representative of the substituted sequence in that it contains a summary of the substituted part.
