Abstract

In one example embodiment, thumbnail management for video content includes detecting a plurality of scene change points from the video content, determining a number of analysis windows based on the plurality of detected scene change points, selecting a frame in each of the analysis windows, and storing the selected frame as the thumbnail for the respective analysis window.

First claim

We claim:

1. A method to select thumbnails corresponding to video content, the method comprising:
detecting a plurality of scene change points from the video content;
setting a number of analysis windows based on the plurality of detected scene change points;
selecting a frame from among frames in each of the analysis windows based on a respective prioritization score for each of the frames in each of the analysis windows;
storing the selected frame as a thumbnail for a respective number of analysis windows; and
providing a user device with the thumbnail for identifying context of the video content.

2. A method to select thumbnails corresponding to video content, the method comprising:
determining at least one of analysis windows for the video content based on a required number of thumbnails;
selecting a frame from among frames in each of the analysis windows based on a respective prioritization score for each of the frames in each of the analysis windows;
storing the selected frame as a thumbnail for the respective at least one of analysis windows; and
providing a user device with the thumbnail for identifying context of the video content.

3. A method to select thumbnails corresponding to video content, the method comprising:
detecting a plurality of scene change points from the video content;
dividing the video content into at least one of portions based on the plurality of detected scene change points;
extracting a frame in each of the portions as a thumbnail based on the plurality of detected scene change points; and
providing a user device with the thumbnail for identifying context of the video content.

4. The method of claim 1 , further comprising,
responsive to receiving an activation of the thumbnail from the user device, transmitting or streaming the video content to the user device.
