Claims

A playback device for playing back recorded content,
A specifying means for receiving a content having a corner made up of a group of scenes to be reproduced, and specifying information specifying a start position and an end position of the corner;
A first feature amount extraction unit that divides a designated corner portion of the content designated by the designation unit in units of shots and obtains a first feature amount for each obtained shot;
A second feature amount extraction unit that divides another content different from the content in units of shots and obtains a second feature amount for each obtained shot;
When the first feature value and the second feature value are compared, and the first and second feature values fall within a predetermined threshold, a shot having the second feature value is selected as the corner. and a corner extracting means for extracting a shot,
The first feature quantity extraction unit includes a feature group in a section immediately before the start time of the corner designated by the designation unit, a feature group in a section immediately after the start time, and a feature group in a section from the start time to the end time , To extract the feature group of the section immediately before the end time and the feature group of the section immediately after the end time,
For each shot of the other content, the corner extraction means is a probability immediately before the start of the corner, a probability immediately after the start of the corner, a probability of being in the corner, a probability immediately before the end of the corner, and immediately after the end of the corner. A reproduction apparatus characterized by calculating a certain probability and extracting a section most likely to be a corner based on the calculation result .

The first and second feature quantity extraction means include a feature group for the image in the corner section, a feature group for the voice in the section, and a time feature group such as the start time and duration of the section. The reproduction apparatus according to claim 1, wherein a feature including the feature is extracted.

A content playback program for playing back recorded content,
The content reproduction program is
Accepts content with a corner consisting of scenes to be played and specification of information specifying the start and end positions of the corner,
Of the specified content, the specified corner portion is divided in units of shots, and a first feature amount is obtained for each obtained shot.
Dividing other content different from the content in units of shots, obtaining a second feature amount for each obtained shot,
When the first feature value and the second feature value are compared, and the first and second feature values fall within a predetermined threshold, a shot having the second feature value is selected as the corner. Let the computer execute the process of extracting as a shot of
The processing for obtaining the first feature value includes a feature group of a section immediately before the start time of a designated corner, a feature group of a section immediately after the start time, a feature group of a section from the start time to the end time, and an end time Extract the feature group of the section immediately before and the feature group of the section immediately after the end time,
The process of extracting as a shot of the corner includes, for each shot of the other content, the probability immediately before the start of the corner, the probability immediately after the start of the corner, the probability of being in the corner, the probability immediately before the end of the corner, and the corner A content reproduction program characterized by calculating a probability of being immediately after the end of the video and extracting a section that seems to be the most corner based on the calculation result .
