System and method for generating media bookmarks
View Patent ↗Disclosed herein are systems, methods, and computer-readable media for transmedia video bookmarks, the method comprising receiving a first place marker and a second place marker for a segment of video media, extracting metadata from the video media between the first and second place markers, normalizing the extracted metadata, storing the normalized metadata, first place marker, and second place marker as a video bookmark, and retrieving the media represented by the video bookmark upon request from a user. One aspect further aggregates video bookmarks from multiple sources and refines the first place marker and second place marker based on the aggregated video bookmarks. Metadata can be extracted by analyzing text or audio annotations. Another aspect of normalizing the extracted metadata includes generating a video thumbnail representing the video media between the first place marker and the second place marker. Multiple video bookmarks may be searchable by metadata or by the video thumbnail visually. In one aspect a user profile stores video bookmarks on a per media and per user basis.
1. A method of generating media bookmarks, the method comprising:
receiving a first place marker and a second place marker for a segment of media;
extracting metadata from the segment of media between the first and second place markers;
normalizing the metadata to yield normalized metadata for locating the segment of media independent of media format type and playback device type;
storing the normalized metadata, first place marker, and second place marker as a media bookmark; and
retrieving the segment of media represented by the media bookmark upon request from a user.
2. The method of claim 1 , wherein the metadata is extracted by analyzing at least one of text and audio annotations.
3. The method of claim 1 , the method further comprising:
aggregating media bookmarks from multiple sources; and
refining the first place marker and second place marker based on the media bookmarks.
4. The method of claim 1 , wherein multiple media bookmarks are at least one of text searchable by metadata and visually searchable by the video thumbnail.
5. The method of claim 1 , wherein a user profile stores media bookmarks on a per media and per user basis.
6. The method of claim 1 , wherein normalizing the metadata includes generating a video thumbnail representing the segment of media between the first place marker and the second place marker.
7. The method of claim 6 , wherein the video thumbnail is fixed length.
8. The method of claim 6 , wherein the video thumbnail is variable length.
9. The method of claim 6 , wherein the video thumbnail comprises one or more still frames.
10. The method of claim 6 , wherein the video thumbnail comprises full motion video.
11. The method of claim 6 , wherein the video thumbnail is variable length.
12. A system for generating media bookmarks, the system comprising:
a first module configured to receive a first place marker and a second place marker for a segment of media;
a second module configured to extract metadata from the segment of media between the first and second place markers;
a third module configured to normalize the metadata to yield normalized metadata for locating the segment of media independent of media format and playback device;
a fourth module configured to store the normalized metadata, first place marker, and second place marker as a media bookmark; and
a fifth module configured to retrieve the segment of media represented by the media bookmark upon request from a user.
13. The system of claim 12 , wherein the metadata is extracted by analyzing at least one of text and audio annotations.
14. The system of claim 12 , wherein multiple media bookmarks are at least one of text searchable by metadata and visually searchable by the video thumbnail.
15. The system of claim 12 , wherein normalizing the metadata includes generating a video thumbnail representing the segment of media between the first place marker and the second place marker.
16. A computer-readable medium storing a computer program having instructions for generating media bookmarks, the instructions comprising:
receiving a first place marker and a second place marker for a segment of media;
extracting metadata from the segment of media between the first and second place markers;
normalizing the metadata to yield normalized metadata for locating the segment of media independent of media format and playback device;
storing the normalized metadata, first place marker, and second place marker as a media bookmark; and
retrieving the segment of media represented by the media bookmark upon request from a user.
17. The computer-readable medium of claim 16 , wherein metadata is extracted by analyzing at least one of text and audio annotations.
18. The computer-readable medium of claim 16 , wherein multiple media bookmarks are at least one of text searchable by metadata and visually searchable by the video thumbnail.
19. The computer-readable medium of claim 16 , wherein a user profile stores media bookmarks on a per media and per user basis.
20. The computer-readable medium of claim 1 , wherein normalizing the metadata includes generating a video thumbnail representing the segment of media between the first place marker and the second place marker.
