    摘要： To record both of two digital broadcasts and/or a digital broadcast and an analog broadcast to be delivered by mutually different broadcasting systems even if they are scheduled to be transmitted in mutually overlapping time frames. A data processing apparatus receives a first broadcast signal and a second broadcast signal from mutually different broadcasting systems to record programs, represented by these broadcast signals, on at least one storage medium. The processor includes: a first receiving section to receive the first broadcast signal; a second receiving section to receive the second broadcast signal; a first stream processing section for outputting a stream of a first program represented by the first broadcast signal; a second stream processing section for outputting a stream of a second program represented by the second broadcast signal; and a stream control section that receives the first and second streams and writes the streams on the at least one storage medium in parallel with each other.

    摘要： A key distribution system distributes key data for using content to a second encryption device that has been legitimately outsourced processing by a first encryption device. The first encryption device acquires permission information indicating that the first encryption device has permission to use the content, generates certification information by making an irreversible alteration the to permission information, and transmits the permission information and the certification information to the second encryption device. The second encryption device receives the permission information and the certification information, sends them to a key distribution device, and acquires the key data from the key distribution device. The key distribution device receives the permission information and the certification information, judges whether or not the certification information was generated by the by the first encryption device, and if judging in the affirmative, transmits the key data to the second encryption device.
