    Abstract: PROBLEM TO BE SOLVED: To separately send a signal protected from copying and the other signal, and to record the two signals in the two sessions of an optical disk without disclosing the secret information of copy protection. SOLUTION: A master signal from a master reader 1 is inputted to a copy protection CD encoder 2. CIR processing, EFM modulation, and copy protection processing are executed by the CD encoder 2, and a CD format signal protected from copying is recorded in a first session. The master reader 5 outputs CD-ROM data and PID original signal to the CD encoder 6. The CD encoder 6 executes CIRC processing and EFM modulation, and the output signal of the CD encoder 6 is recorded in a second session. The two signals are switched by a switching part 3. PID is additionally recorded by processing a signal which becomes an original after a reflective film has been coated. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: PURPOSE: To provide a signal supply device which can be easily applied to an existing mobile object and also can improve the S/N, the stability and the reliability. CONSTITUTION: A voice signal supply device includes plural passenger control panels. That is, a branch part 11 of a 1st passenger control panel 41 receives the voice signals from a basic signal line connecting the seat groups together via one side 10a of a branch terminal 10. A buff amplifier 12 amplifies the voice signals and supplies them to an audio decoder 14 and also to an intermediate output terminal 13. The decoder 14 applies the decoding processing to the amplified voice signals sent from the amplifier 12 such as the error correction and decoding, etc. Then the panel 41 that received the voice signals from the basic signal line via a pair of terminals 10 supplies the voice signals amplified by the amplifier 12 to the buffer amplifiers 19 and 26 of the passenger control panels 51 and 61 respectively from the terminal 13 via an intra-group signal line.

    Abstract: PURPOSE:To simultaneously operate a bootstrap to plural diskless computers without increasing a network traffic by simultaneously supplying bootstrap data to the plural computers after a prescribed time at the time of receiving the request of the bootstrap data. CONSTITUTION:When a power source is turned on, each diskless computer 11a, 11b,...11n reads bootstrap data request program data from an ROM, and issues the bootstrap data request through a network 3 to a file server 10 by the read bootstrap data request program shown by arrows r1 and r2. The file server 10 detects the bootstrap data request through the network 3 from the diskless computers 11a, 11b,...11n, and supplies the bootstrap data through the network 3 to each disk less computer 11a, 11b,... 11n in the form of a broadcast packet.

    Abstract: PROBLEM TO BE SOLVED: To safely transmit and receive a content between a source and a sink.SOLUTION: The information processing apparatus comprises: a source 110 being a content output device; and a sink 210 being a content input device. Between the source and the sink, the information processing apparatus performs a first stage authentication processing S101 to share first encryption keys 121, 221, and performs a second stage authentication processing S102 having a different method from that of the first stage authentication processing S101 to share second encryption keys 122, 222. The source, to an output content, generates an encrypted content using the first encryption key 121 and the second encryption key 122, and outputs the generated encrypted content to the sink. The sink, to the encrypted content received from the source, performs decryption processing using the second encryption key 222 and the first encryption key 221 to acquire the content.
