Claim:
A content receiving device that is connected to a predetermined local network, the content receiving device comprising: a receiver that receives a stream in which data of a content containing video is divided into a plurality of packets; an extractor that extracts, in a case where the stream received by the receiver is an encrypted stream, a key for decrypting the encrypted stream from the stream; a first decryptor that decrypts, by using the key, only a specific packet among the plurality of packets; an encryptor that encrypts the key extracted by the extractor, by using a unique key of the content receiving device, the encrypted stream that includes the key encrypted by the encryptor is recorded in a recording section; a second decryptor that decrypts, by using the key, the encrypted stream recorded in the recording section; a processor that creates a new stream that is suitable for the local network, based on the stream decrypted by the second decryptor, the processor having a table processor that creates a new PMT (Program Map Table) that is suitable for the local network, based on a PMT included in the encrypted stream recorded in the recording section; and a transmitter that transmits the new stream created by the processor towards another apparatus through the local network.
