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, and storing the sequence record.

First claim

What is claimed is:

1 . A method for tagging a video presentation played on a multimedia unit with at least one sequence record, said method comprising the steps of:
during the playing of the 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 indicates a location of the marked portion of the video presentation; editing the sequence record of the video presentation that comprises the time index or frame index, wherein 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 and comprises:
receiving from a user textual information which corresponds to the sequence record of the video presentation;
adding the textual information received from the user to the sequence record; and
storing the edited sequence record of the video presentation that contains the corresponding textual information received from the user.

2 . The method of claim 1 , wherein 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 being 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 , further comprising:
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 of the sequence records 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 of the sequence records to the user is synchronized in advance of time with the video presentation according to a predefined time.

10 . A decoder for tagging a video presentation, said decoder comprising:
a video decoder configured to decompress a compressed video stream and output the decompressed video stream to a display unit; a processing device configured to execute a program; a first memory to store at least the program; a second memory for storing non-executable data; and an input to receive a command from a user; wherein said decoder is configured to perform the following steps:
during the playing of the video presentation, 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 indicates a location of the marked portion of the video presentation;
editing the sequence record of the video presentation that comprises the time index or frame index, wherein the editing of the sequence record of the video presentation occurs after completion of the playing of the broadcast video presentation and comprises:
receiving textual information which corresponds to the edited sequence record of the video presentation from the user; and
adding the textual information received from the user to the sequence record; and

storing the edited sequence record of the video presentation that contains the corresponding textual information.

11 . The decoder of claim 10 , wherein editing the sequence record further comprises:
adding a tag category to identify the type of video sequence.

12 . The decoder of claim 10 , wherein the sequence record further comprises an identifier of the user, said identifier being obtained automatically from the multimedia unit or being introduced during the editing the sequence record.

13 . The decoder of claim 10 , wherein the sequence record comprises a publication state indicating if the record is:
private; can be shared within a specific group; or publicly available.

14 . The decoder of claim 10 , 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.

15 . The decoder of claim 10 , wherein editing the sequence record further comprises saving the sequence record to a remote database.

16 . The decoder of claim 15 , further configured to perform the steps of:
requesting one or more of the sequence records stored in the remote database; and displaying to the user the sequence records.

17 . The decoder of claim 16 , wherein the display of the sequence records to the user is synchronized with the video presentation using the time index or frame index contained in the sequence record.

18 . The decoder of claim 16 , wherein the display of the sequence records to the user is synchronized in advance of time with the video presentation according to a predefined time.
