Abstract

The present invention relates to a method for identifying an audiovisual document. Initially, the user programs the recording in an audiovisual content device with the aim of recording a determined document. Once the recording has been performed, the device detects and displays identifiers associated with shots extracted from the recorded content, each associated shot having at least one determined characteristic. An indication of the probability associated with each shot so that said shot is indeed the shot identifying the start or the end of said document is also displayed. Then, the user introduces a selection command for a displayed identifier, the start or the end of said document being identified by the shot associated with the selected identifier. The invention also relates to a receiver featuring a user interface implementing the method.

Claims

1. Method for identifying an audiovisual document within a reproduction device, said document being part of a recorded content also containing a part that does not belong with said document, wherein it comprises the steps of:

a displaying of identifiers associated with shots having determined characteristics and a display with an indication of the probability associated with each shot that this shot is indeed the identifier of the start or the end of said document,

an identification of the start or the end of said document by the introduction of a displayed identifier selection command into the reproduction device, the start or the end of said document having been identified by the shot associated with the selected identifier.

2. Method for identifying an audiovisual document according to claim 1, wherein the probability value of a given shot is a function of the number of preceding shot selections having the same determined characteristic as the given shot.

3. Method for identifying an audiovisual document according to claim 1, wherein the probability value of a shot depends on the detection method based on the determined characteristic that enabled its detection and the display of its identifier.

4. Method for identifying an audiovisual document according to claim 1, wherein, following the identification of the start or the end of said document by the introduction of a selection command, the probability value of a given shot is increased if the duration between this given shot and the shot selected by the command correspond to the duration of the document.

5. Method for identifying an audiovisual document according to claim 1, wherein the displaying presents shot identifiers according to an order depending on their respective probability values.

6. Method for identifying an audiovisual document according to claim 1, wherein the shot identifier having the highest probability is graphically highlighted.

7. Method for identifying an audiovisual document according to claim 1, wherein the detection only detects shots over a determined period from the start of the recorded content and/or from the end of the recorded content.

8. Method for identifying an audiovisual document according to claim 1, wherein the selection is carried out on the shot immediately preceding the shot that is identified as being the start of the document, or on the shot immediately after the shot that is identified as being the end of the document.

9. Display device comprising a means to command the recording of a document and a means to record an audiovisual content comprising said document and at least one part not belonging to said document,

wherein it comprises a means to display the identifiers associated with the shots from recorded content and an indication of the probability associated with each shot so that said shot is indeed the shot identifying the start or end of said document, said associated shots having a determined characteristic and,

a means of introducing a selection command for one of the displayed identifiers, the start or end of said document being identified by the shot associated with the selected identifier.

10. Display device according to claim 9, wherein it comprises a means to calculate the probability value of a given shot taking into account the number of preceding shot selections having the same determined characteristic as the given shot.

11. Display device according to claim 9, wherein it comprises a means to calculate the probability value of a given shot taking into account the detection method based on the determined characteristic that enabled its detection and the display of its identifier.

12. Display device according to claim 9, wherein it comprises a means to calculate the probability value of a given shot taking into account the duration of the document and the shot selection as the start or end of the document, if the period between the given shot and the selected shot is equal to the duration of the document, the probability of the given shot is increased.

13. Display device according to claim 9, wherein the display means presents the shot identifiers according to an order depending on their respective probability values.

14. Display device according to claim 9, wherein the display means presents the shot identifier having the highest probability value with a graphical distinction.
