摘要： The cloning source of an authorized receiving device cannot be identified. A key distribution system 1 concerning the present invention includes: a communication channel 10; a key distribution center 11; a server 12; and receiving devices 13a to 13n. The key distribution center 11 distributes, to the server 12, the information necessary for distributing shared keys SK to the receiving devices 13a to 13n, and distributes the individual information group EMMG necessary for receiving the shared keys SK from the server 12. The server 12 generates the shared keys SK, generates the common information ECM based on the shared keys SK and the system secret variable group set SPGS, and distributes the common information ECM to the receiving devices 13a to 13n. The receiving devices 13a to 13n obtain the shared keys SK based on the individual information group EMMG and the common information ECM and outputs them to outside.

摘要： To provide a system that can minimize a time delay caused by one device being unable to access a recording medium until access by another device ends, when transcoding is performed by distributed processing. A main device performs transcoding of each coded piece allocated to itself from among a plurality of coded pieces of a digital stream, and writing of a transcoding result onto the recording medium, in a pipeline. While the recording device is performing the transcoding and the writing, an auxiliary device transcodes each coded piece allocated to itself one by one. Having completed the transcoding of all coded pieces allocated to itself, the auxiliary device transmits its transcoding results to the recording device and has the recording device write the transcoding results onto the recording medium which is a copy destination.

摘要： An unauthorized apparatus detection device, playback device, unauthorized apparatus detection system, information collection device, unauthorized apparatus detection method, a program, recording medium, apparatus information update method, and integrated circuit can detect clones of a playback device. In a management server 2, a reception processing unit 241 acquires a user terminal identifier and a first random number from a user terminal targeted for unauthorized apparatus detection, judges whether a second management server random number, which is stored in a storage unit 23 in correspondence with the user terminal identifier, matches the first user terminal random number. If the two fail to match, a display unit 22 displays a message indicating that a clone exists. If the two match, a terminal information generation unit 243 generates a new random number, and writes the generated random number as the second random number in the storage unit 23. A transmission processing unit 246 transmits the generated random number to the user terminal via a transmission/reception unit 246 and the user terminal updates the first user terminal random number to the generated random number.
