Video reception device and image recognition method for received video

摘要

A video reception device connected to an image recognition device for performing image recognition includes: a video input unit that receives a video including content items switches of which occur as time elapses; a video extraction unit that extracts from the video a partial video which is a portion of the video; a content switchover detection unit that detects whether or not the partial video includes content switchover indicating switchover of the content items; and a control unit that performs, when the content switchover detection unit detects that the partial video includes no content switchover, a control to output the partial video to the image recognition device to obtain a result of the image recognition for the partial video from the image recognition device.

1. A video reception device connected to an image recognition device for performing image recognition, the video reception device comprising:
a video input unit configured to receive a video including content items switches of which occur as time elapses; a video extraction unit configured to extract from the video a partial video which is a portion of the video, the partial video having a predetermined time length; a content switchover detection unit configured to detect whether or not the partial video includes content switchover indicating switchover of the content items; and a control unit configured to perform, when the content switchover detection unit detects that the partial video includes no content switchover, a control to output the partial video to the image recognition device to obtain a result of the image recognition for the partial video from the image recognition device, wherein the video extraction unit is configured to repeatedly extract a new partial video from the video, the content switchover detection unit is configured to perform the detection every time the video extraction unit extracts the partial video, and the control unit is configured to perform the control every time the content switchover detection unit performs the detection, and when the content switchover detection unit detects that the partial video includes the content switchover, the control unit is configured to, without outputting the partial video to the image recognition device, cause the video extraction unit to extract a new partial video.
