Content division position determination device, content viewing control device, and program

A content division position determination method for determining temporal division positions of a content, the method comprising:

• detecting, when supplied with at least one content, a group of repetitive signal sections in which signals are similar to one another as a repetitive signal section group from the content and outputting information for identifying each of the repetitive signal sections contained in the repetitive signal section group as repetitive signal section group information (termed as “repetitive signal section group detection step”);
• extracting, from the content, preceding and following section description feature values, which are feature values describing the preceding and following sections of each of the repetitive signal sections identified by the repetitive signal section group information by a computer (termed as “preceding and following section description feature value extraction step”);
• and
• calculating a division position reliability that indicates a probability that each of the repetitive signal sections contained in the repetitive signal section group indicates a division position by using the preceding and following section description feature values corresponding to a plurality of repetitive signal sections contained in the repetitive signal section group by said computer (termed as “preceding and following section description feature value analysis step”).

A program causing a computer to execute a content division position determination process to determine temporal division positions of a content, the program causes a computer to execute:

• a repetitive signal section group detection process to detect, when supplied with at least one content, a group of repetitive signal sections in which signals are similar to one another as a repetitive signal section group from the content and outputting information for identifying each of the repetitive signal sections contained in the repetitive signal section group as repetitive signal section group information;
• a preceding and following section description feature value extraction process to extract, from the content, preceding and following section description feature values, which are feature values describing the preceding and following sections of each of the repetitive signal sections identified by the repetitive signal section group information;
• and
• a preceding and following section description feature value analysis process to calculate a division position reliability that indicates a probability that each of the repetitive signal sections contained in the repetitive signal section group indicates a division position by using the preceding and following section description feature values corresponding to a plurality of repetitive signal sections contained in the repetitive signal section group.
