Program, information processing device, content processing method, and content processing system

An information processing device which processes content transmitted from a transmission device, the information processing device comprising:

• a reception unit for receiving the content, and first verification data corresponding to divided content obtained by dividing the content, from the transmission device;
• a detecting unit for detecting an error of the divided content based on second verification data to be calculated based on the divided content, and the first verification data received by the reception unit;
• and
• an obtaining unit for obtaining other divided content corresponding to the divided content having the error detected by the detecting unit from another information processing device different from the transmission device, when the error of the divided content is detected by the detecting unit.

A content processing method for processing content transmitted from a transmission device to an information processing device, the method comprising:

• a receiving operation for receiving the content and first verification data corresponding to divided content obtained by dividing the content, from the transmission device;
• a detecting operation for detecting an error of the divided content based on second verification data to be calculated based on the divided content, and the first verification data received in the receiving operation;
• and
• an obtaining operation for obtaining other divided content corresponding to the divided content having the error detected in the detecting operation from another information processing device different from the transmission device, when the error of the divided content is detected in the detecting operation.

A content processing system, which includes a transmission device and an information processing device, for processing, in the information processing device, content transmitted from the transmission device, wherein the transmission device includes

• a transmission unit for transmitting the content and first verification data corresponding to divided content obtained by dividing the content, to the information processing device;
• and
• the information processing device includes:
• a reception unit for receiving the first verification data corresponding to the content and the divided content from the transmission device;
• a detecting unit for detecting an error of the divided content based on second verification data to be calculated based on the divided content, and the first verification data received by the reception unit;
• and
• an obtaining unit for obtaining other divided content corresponding to the divided content having the error detected by the detecting unit from another information processing device different from the transmission device, when the error of the divided content is detected by the detecting unit.
