Further, the management data generating means 5 uses the first time code in the sentence start time list as a reference,
The time code of the caption character string list that falls within a certain time difference is extracted, and a candidate list is generated. Next, the difference time between the first time code and the second time code in the sentence start time list is compared with the difference time between the n-th time code and the (n + 1) -th time code in the candidate list. By extracting, it is considered that the time code of the sentence start time list matches the time code of the caption character string list. This uses the fact that the time length of a sentence changes according to the number of caption characters, and confirms the association between the sentence and the caption character string, and compares the sentence length and the number of caption characters in a simulated manner. Will be.
As a result, the accuracy of associating the caption character string with the sentence head time can be improved.
