    • PROBLEM TO BE SOLVED: To prevent the copy and reproduction of data due to the alteration act of a CCI by storing CCI in the user region of a storage medium such as an SD memory card. SOLUTION: This one segment receiver is provided with a controller 7. The controller 7 generates packets 31, 32 and so on for control having a non-cryptographic part 43 obtained by setting copy control information(CCI) 46 showing conditions for copying data and a cryptographic part 44 obtained by arranging CCI47 obtained by duplicating the CCI46 and an alternation detection code 48(predetermined information) at predetermined positions, and encrypting them by a predetermined encryption system, and stores the file constituted of the plurality of generated packets in a user region 12.

    • PURPOSE:To simplify the operation to hear selectively only desired information programs or music sources by combining music sources on the outside of a receiver and a sound recorder by a means switch and a logic circuit. CONSTITUTION:A program discriminating signal superposed to a carrier wave or an audio band is demodulated by a tuner 2 in the reception side and is outputted from a speaker 6 through a switch 4 and an amplifier 5. The demodulated output is applied to a program discriminating signal detecting circuit 8 to detect program start and end patterns of the demodulated signal, and these patterns are applied to a coincidence detecting circuit 9. The coincidence between these patterna and preliminarily set program start and end code patterns 10 and 11 is detected by the circuit 9, and the coincidence detection output is processed by an F circuit 13 to record required information on a sounc recorder 7, and information indicating recording is displayed on a reporting device 14. A tape player 7 as the music source on the outside of the receiver is connected to the other terminal of the switch 4, and AND between the output of a manual switch 16 and the output of the circuit 13 is operated by an AND circuit 15, and the switch 4 is switched by the output of the AND circuit 15, thus selecting music and desired information programs.

    • PROBLEM TO BE SOLVED: To shorten a period of time needed to start reproduction when reproducing a content recorded by a broadcast receiver.
      SOLUTION: The broadcast receiver is provided with: a generating means for generating a first encryption key inherent to the broadcast receiver having identification information; a retrieving means for retrieving first individual information and second individual information located the most ahead in time, wherein a broadcast stream includes an individual information stream included in a prescribed channel of a broadcast wave and a content stream requiring a second encryption key for decryption, and the individual information stream periodically includes first individual information required to generate the first encryption key in the generating means and second individual information which includes a second encryption key and can be decrypted by the first encryption key; and an overwriting means for overwriting the second individual information discovered by the retrieving means ahead of the position with the second individual information discovered in time and more subsequently in time than the first individual information discovered by the retrieving means in the individual information stream.
