Abstract

A method for identifying popular segments of a network video comprising: receiving video player operation information for a plurality of video players operated by users accessing the network video; evaluating a popularity measure for one or more segments of the network-video using the received operation information so as to identify popular segments of the network video.

First claim

What is claimed is:

1. A method for identifying popular segments of a network video comprising:
receiving video player operation information for a plurality of video players operated by users accessing the network video;
evaluating, using a processor, a popularity measure for a segment of the network-video using the received operation information so as to identify popular segments of the network video, wherein
the network video comprises a plurality of video segments,
the video player operation information for a particular video player regards one or more operations performed by the video player, and
a predetermined policy is used to evaluate the popularity measure R vi for a video segment using the following equation:

wherein, vi represents a video segment, T vi is the time length of the segment, A represents scan forward, B represents scan backward, C represents fast forward and D represents fast backward, t Ai is a duration of a scan forward operation by an ith user in the segment during a current viewing, t Bi is a duration of a scan backward operation by the ith user in the segment during the current viewing, t Ci is a duration of a fast forward operation by the ith user in the segment during the current viewing, and t Di is a duration of a fast backward operation by the ith user in the segment during the current viewing, and K A , K B , K C and K D are weightings for the drag forward, drag backward, fast forward, fast backward operations respectively and m represents a number of the users.

2. The method according to claim 1 , wherein
evaluating the popularity measure further comprises:
dividing the network video into the plurality of video segments; and
evaluating the popularity measure for each of the plurality of video segments using the predetermined policy defining popularity indicators for the network video.

3. The method according to claim 2 , wherein
the operations comprise at least one of a scan forward operation, a scan backward operation, a fast forward operation, a fast backward operation, a rewind operation and a pause operation.

4. The method according to claim 3 , wherein
the predetermined policy defines popularity indicators for network video in terms of at least one of:
a duration of a scan forward operation in a video segment during viewing by a user;
a duration of a scan backward operation in a video segment during viewing by a user;
a duration of a rewind operation in a video segment during viewing by a user;
a duration of a fast forward operation in a video segment during viewing by a user; and
a duration of a pause operation in a video segment during viewing by a user.

5. The method according to claim 1 further comprising
displaying the identified popular segments of network video as segments satisfying one or more display criteria defining a threshold popularity measure.

6. The method according to claim 5 , wherein displaying further comprises:
visually displaying the popularity information on a network video player.

7. The method according to claim 6 , wherein displaying further comprises:
visually indicating the identified popular segments of network video on a progress bar of the video player, with a variation in color or brightness representing a relative level of popularity of one or more video segments.

8. The method according to claim 1 further comprising:
creating a condensed version of the network video comprising a subset of segments of the network video evaluated to be the most popular segments of the network video.

9. The method according to claim 8 , wherein
the condensed version of the network video is created based on user defined criteria.

10. The method according to claim 8 wherein
the condensed version of the network video is smoothed by using at least one of an interpolation method and an expansion method.

11. An apparatus for identifying popular segments of a network video comprising:
a receiver component for receiving video player operation information for a plurality of video players operated by users accessing the network video;
an evaluation component for evaluating a popularity measure for a segment of the network-video using the received operation information so as to identify popular segments of the network video, wherein
the network video comprises a plurality of video segments,
the video player operation information for a particular video player regards one or more operations performed by the video player, and
a predetermined policy is used to evaluate the popularity me
