Abstract

The exemplary embodiments of the present invention provide a method for generating an annotation for media content, that includes retrieving a media content subset from a media content source, saving the received media content subset at a computing system, and generating an annotation for association with the media content subset using the computing system. The method further includes associating the annotation with media content to facilitate the visualization and navigation of the media content and adding the annotation to at least one annotation repository designed for efficient retrieval of annotation elements.

Claims

1. A method for generating an annotation for media content, the method comprising:

retrieving a media content subset from a media content source;

saving the received media content subset at a computing system;

generating an annotation for association with the media content subset using the computing system;

associating the annotation with media content to facilitate the visualization and navigation of the media content, the annotation providing a graphical representation directing a user to a region of interest in the media content thereby visually presenting the location of associative information parameters of the media content enabling visual navigation of the media content; and

adding the annotation to at least one annotation database for retrieval of annotation elements,

wherein the content of the annotation contains an index point delimiting the beginning of the region of interest within the media file.

2. The method in claim 1, wherein the processing of the media content received by the computing system involves at least one remote computing system accessible to the computing system.

3. The method in claim 1, wherein the at least one annotation repository is stored on the computing system.

4. The method in claim 1, wherein the at least one annotation repository is stored on at least one remote computing system.

5. The method of claim 1, wherein the associating the annotation is with a particular time instance in the media file.

6. The method of claim 1, further comprising sharing the annotation with another user.

7. The method of claim 6, wherein the content of the annotation contains user-defined information.

8. A system for generating an annotation for media content, comprising:

a device for sending a request to generate the annotation; and

a processor for receiving the request, wherein the processor performs a method comprising;

retrieving a media content subset from a media content source;

saving the received media content subset on a computing system;

generating an annotation for association with the media content subset using the computing system;

associating the generated annotation with the media content to facilitate the visualization and navigation of the media content, the annotation providing a graphical representation directing a user to a region of interest in the media content thereby visually presenting the locations of associative information parameters of the media content enabling visual navigation of the media content, and

adding the annotation to at least one annotation database for retrieval of annotation elements,

wherein the content of the annotation contains an index point delimiting the ending of the region of interest within the media file.

9. The system of claim 8, wherein the content of the annotation contains user-defined information.

10. The system of claim 8, wherein the associating the annotation is with a particular time instance in the media file.

11. The system of claim 8, wherein the at least one annotation database is stored on at least one remote processor.

12. The system of claim 8, wherein the at least one annotation database is stored on the processor.

13. The system of claim 8, wherein the content of the annotation contains an index point delimiting the beginning of the region of interest within the media file.

14. The system of claim 8, wherein the annotation is shared with another user.

15. A computer program product for generating an annotation for media content, the computer program product comprising:

a tangible storage medium readable by a computer system and storing instructions or execution by the computer system for performing a method comprising;

retrieving a media content subset from a media content source;

saving the received media content subset at a computing system;

generating an annotation for association with the media content subset using the computing system;

associating the annotation with media content to facilitate the visualization and navigation of the media content, the annotation providing a visual marker directing a user to a region of interest in the media content thereby visually presenting the locations of associative information parameters of the media content enabling visual navigation of the media content; and

adding the annotation to at least one annotation database for retrieval of annotation elements,

wherein the content of the annotation contains a first index point delimiting the beginning of the region of interest within the media file, and a second index point delimiting the ending of the region of interest within the media file.

16. The computer program product of claim 15, wherein the processing of the media content received by the computing system involves at least one remote computing system accessible to the computing system.

17. The computer program product of claim 15, wherein the content of the annotation contains user-defined information.
