Abstract

The present invention proposes a method to mark and exploit at least one sequence record of a video presentation played on a multimedia unit, said method comprising the steps of:—during the video presentation, receiving a command from a user to mark a currently displayed video sequence, said command initiating the step of:—creating a sequence record comprising a time index or frame index, allowing to locate the proper part of the video presentation, and a reference of the video presentation, At a later stage, requesting the edition of the sequence record by:—adding textual information which corresponds to the actual sequence,—storing the sequence record.

First claim

The invention claimed is:

1. A method for marking and editing at least one sequence record of a video presentation broadcasted from a broadcast center and played on a multimedia unit, said method comprising the steps of:
during the playing of the broadcasted video presentation, receiving a command, at the multimedia unit, from a user to mark a currently displayed video sequence of the video presentation;
creating, at the multimedia unit, a sequence record comprising a time index or frame index, and a reference of the video presentation;
wherein the time index or frame index allows the user to locate the marked portion of the video presentation; and
editing the sequence record of the video presentation that comprises the time index or frame index;
whereby the editing of the sequence record of the video presentation occurs at the multimedia unit after completion of the playing of the broadcast video presentation, by:
adding textual information which corresponds to the edited sequence record of the video presentation; and
storing the edited sequence record of the video presentation that contains the corresponding textual information.

2. The method of claim 1 , wherein the editing the sequence record further comprises:
adding a tag category to identify the type of video sequence.

3. The method of claim 1 , wherein the sequence record further comprises an identifier of the user, said identifier being obtained automatically from the multimedia unit or it can be introduced during the editing the sequence record.

4. The method of claim 1 , wherein the sequence record comprises a publication state indicating if the record is:
private;
can be shared within a specific group; or
publicly available.

5. The method of claim 1 , wherein the sequence record comprises a video sample of the time corresponding to the index in the form of a still image or an video extract.

6. The method of claim 1 , wherein editing the sequence record further comprises saving the sequence record to a remote database.

7. The method of claim 6 , wherein the editing the sequence record further comprises:
requesting one or more of the sequence records stored in the remote database; and
displaying to the user the sequence records.

8. The method of claim 7 , wherein the display to the user is synchronized with the video presentation using the time index or frame index contained in the sequence record.

9. The method of claim 7 , wherein the display to the user is synchronized in advance of time with the video presentation according to a predefined time.

10. A decoder for displaying a broadcasted video presentation from a broadcast center, said decoder comprising a video decoder receiving a compressed video stream and an output toward a display unit, a processing device to execute a program, a memory to store at least a program and a memory to store non executable data, an input to receive a command from a user, said decoder being configured to perform the following steps:
during the playing of the broadcasted video presentation from the broadcast center, receiving a command from a user to mark a currently displayed video sequence of the video presentation;
creating a sequence record comprising a time index or frame index and a reference of the video presentation;
wherein the time index or frame index allows the user to locate the marked portion of the video presentation; and
editing the sequence record of the video presentation that comprises the time index or frame index;
whereby the editing of the sequence record of the video presentation occurs after completion of the playing of the broadcast video presentation by:
adding textual information which corresponds to the edited sequence record of the video presentation; and
storing the edited sequence record of the video presentation that contains the corresponding textual information.
