Abstract

A system of this invention is a video processing system for determining details of a browsable video content. This video processing system includes a video fragment download unit that downloads data of a video fragments in a determination target video content via a network, and a first video content determination unit that determines the details of the video content based on the downloaded data of the video fragments. With this arrangement, it is possible to determine the details of a browsable video content while reducing the amount of data to be downloaded.

First claim

What is claimed is:

1. A video processing system comprising:
a video fragment download unit, implemented at least in hardware including a processor and memory, that downloads, via a network, data of video fragments, each selected without consideration of video scene and including a series of a plurality of frames, in a target video content to be determined; and
a first video content determination unit, implemented at least in the hardware, that determines the target video content based on the downloaded data of the video fragments,
wherein said video fragment download unit comprises an algorithm storage that stores a plurality of different algorithms in association with a type of the video content as the determination target of said first video content determination unit, and selects the video fragments to be downloaded from the video content using an algorithm corresponding to the type of the video content as the determination target of said first video content determination unit, and
said first video content determination unit determines, based on comparison between a series of frame features, each extracted from each frame of a video fragment, and a series of frame features of a video content registered in advance, whether a video scene including the video fragments matches a video scene of the video content registered in advance or whether a video content including the video fragments matches the video content registered in advance.

2. The video processing system according to claim 1 , further comprising a first illegality determination unit that determines that the video content including the video fragments has illegality, when said first video content determination unit has determined that the video scene including the video fragments matches the video scene of the video content registered in advance or that the video content including the video fragments matches the video content registered in advance.

3. The video processing system according to claim 2 , further comprising a second determined result notification unit that notifies a video content distribution site having the video content or an upload source that has uploaded the video content to the video content distribution site, of a determined result by said first illegality determination unit.

4. The video processing system according to claim 1 , further comprising a video content selector that selects, from video contents uploaded to a video content distribution site, the target video content to be determined including the data of the video fragments to be downloaded by said video fragment download unit.

5. The video processing system according to claim 4 , wherein said video content selector includes a video content crawler that crawls the video content uploaded to the video content distribution site.

6. The video processing system according to claim 1 , further comprising:
a content download unit, implemented at least in the hardware, that downloads data of a whole video content when it is judged to be necessary to more accurately determine details of the video content from a determined result of said first video content determination unit; and
a second video content determination unit, implemented at least in the hardware, that determines the details of the video content from the downloaded data of the whole video content.

7. The video processing system according to claim 4 , wherein said second video content determination unit determines a level of matching between the whole video content and the video content registered in advance or between the whole video content and the video scene of the video content registered in advance, based on comparison between a series of frame features extracted from the whole video content and the series of frame features of the video content registered in advance.

8. The video processing system according to claim 7 , further comprising a video content distribution site distributing the video content having a frame feature extractor that extracts frame feature, wherein the series of frame features of the whole video content are downloaded from the video content distribution site via the network.

9. The video processing system according to claim 7 , wherein the frame feature is data obtained by combining differences as many as a number of region pairs on each frame, each of the differences being a difference between a pair of region features calculated for each of the region pairs, each region of the each of the region pairs formed on the each frame in different sizes.

10. The video processing system according to claim 9 , wherein the region features are represented by a luminance.

11. The video processing system according to claim 6 , further comprising a second illegality determination unit that determines that the video content has illegality, when said second video content determination unit has determined that the level of matching between the whole video content and the video content registered in advance or between the whole video content and the video scene of the video content registered in advance satisfies a predetermined condition.

12. The video processing system according to claim 11 , further comprising a fourth determined result notification unit, implemented at least in the hardware, that notifies the video content distribution site having the video content or an upload source that has uploaded the video content to the video content distribution site, of a determined result by said second illegality determination unit.

13. The video processing system according to claim 6 , further comprising a third determined result notification unit that notifies a video content distribution site having the video content or an upload source that has uploaded the video content to the video content distribution site, of a determined result by said second video content determination unit.

14. The video processing system according to claim 1 , further comprising a video content distribution site distributing the video content having a frame feature extractor that extracts frame feature, wherein the series of frame features of the video fragments are downloaded from the video content distribution site via the network.

15. The video processing system according to claim 1 , wherein the frame feature is data obtained by combining differences as many as a number of region pairs on each frame, each of the differences being a difference between a pair of region features calculated for each of the region pairs, each region of the each of the region pairs formed on the each frame in different sizes.

16. The video processing system according to claim 15 , wherein the region features are represented by a luminance.

17. The video processing system according to claim 1 , further comprising a controller that controls a processing procedure by said video fragment download unit and said first video content determination unit when determining a plurality of video contents,
wherein said controller controls repeating download by said video fragment download unit and determination by said first video content determination unit for a predetermined number of video fragments of each video contents, but stopping the subsequent download and determination for the each video contents when the determination by said first video content determination unit has been established.

18. The video processing system according to claim 1 , further comprising a controller that controls a processing procedure by said video fragment download unit and said first video content determination unit when determining a
