The video signal is divided into shot units. Next, the feature value of the shot is calculated. Here, a still image (hereinafter, referred to as a representative frame) that best represents the feature is selected,
The color average value of each block obtained by dividing the representative frame into four is used as the characteristic value of the shot. As the representative frame, the first image signal of the shot, the image signal at the center in time, the frame obtained by summing the pixel values of all the frames, and the like can be used. Use the first image signal. That is, the feature value of one shot is represented by 12 numerical values. The video feature value storage device 32 stores the color feature values thus calculated, the start point (time) of the shot, the end point (time), and four types of values of the included program name.

When the characteristic value of the shot is obtained, the characteristic value close to the characteristic value of the shot is searched from the characteristic value of the video characteristic value storage device 32. The closeness of the value is calculated by a 12-dimensional vector distance, and threshold processing is performed. When there is a video whose characteristic value is equal to or smaller than the threshold value, the video-related information storage device 33 stores the relevant information (the program name included therein and the start point and the end point) for linking shots having the characteristic. The video search is performed as described above.

For example, if news dealing with a certain subject broadcasts the same video material, the color characteristics of the video signals are very similar to each other and can be selected as related video. For example, it is possible to describe the news related to the same station in different time zones or, in some cases, the news of the same content in a news program of another station.
