摘要

600198 Disclosed is a content-receiving and decrypting device (10). The device (10) is comprised of a receiving section (20), an extraction section (23) and a decryption section (24). The receiving section (20) receives a stream in which data of a content containing video is divided into a plurality of PESs (Packetized Elementary Streams). Each one of the PESs includes a plurality of packets. The extraction section (23) extracts from the stream, in a case where the stream received by the receiving section (20) is an encrypted stream, a key for decrypting the encrypted stream. The decryption section (24) decrypts, by using the key, only a specific packet among the plurality of packets included in each one of the PESs.
