摘要： An information processing device is provided that includes a signal receiving portion, an absolute value conversion portion, and an input data decoding portion. The signal receiving portion receives a signal that is encoded such that mutually distinct first and second bit values are respectively expressed by pluralities of mutually distinct first amplitude values and second amplitude values, the first and second bit values also being encoded such that the same amplitude value does not occur twice in succession and such that the polarities of the amplitude values are inverted with each cycle. The absolute value conversion portion converts into absolute values the amplitude values of the signal that has been received by the signal receiving portion. The input data decoding portion decodes the first and second bit values based on the amplitude values in the signal that have been converted into absolute values by the absolute value conversion portion.

摘要： A radio communication system is formed of a plurality of radio communication terminals and a radio communication control terminal for controlling radio communication. Data communication is performed between each radio communication terminal and the radio communication control terminal by the orthogonal frequency division multiplexing (OFDM) method. Data is multiplexed with a frame structure having the specified number of symbols by the TDMA method. The radio communication control terminal transmits a synchronization acquisition code to the plurality of radio communication terminals in each frame. Each radio communication terminal receives the synchronization acquisition code, sets a timer according to the receiving timing of the synchronization acquisition code, and sets the transmission timing and the receiving timing with the timer being used as the reference. With the use of the OFDM method, demodulation is performed without an error even if jitter occurs. Since the timing of transmission and receiving is set with an M sequence at the top of a frame being used as a reference, the timer of each radio communication terminal is set to the same time. With the use of this time information, only necessary symbols in a frame are demodulated to reproduce the data at receiving.

摘要： The level of the spectrally spread anti-duplication control signal to be superimposed on an information signal such as a video signal is changed by using a random number RD generated by a random number generation unit 163. Since it is difficult to follow after the change of the level of the spectrally spread anti-duplication control signal, elimination of the anti-duplication control signal from the information signal is made further difficult. This can reliably provide the anti-duplication control signal to the receiving side.

摘要： A playback device generates a Pseudo-random noise (PN) code sequence repeatedly with a predetermined period in synchronism with a video sync signal. An anti-duplication control signal is spectrally spread using this generated PN code sequence, is superimposed on the video signal, and is output. A PN code sequence having the same timing and code pattern as the PN code sequence used in the playback device is similarly generated based on the video sync signal on the receiving side which receives the output video signal. Using this PN code sequence, reverse spectral spread is performed, the anti-duplication control signal superimposed on the video signal is extracted, and anti-duplication control is performed according to the extracted anti-duplication control signal.

摘要： The invention intends to secure the control of duplicating information signals. In the duplication control method according to the invention, a main information signal containing a duplication control information transformed into a spread spectrum signal to be superimposed and a duplication control information superimposed by a processing different from the spectrum spreading is transmitted. The duplication control information transformed into a spread spectrum signal is extracted from the main information signal by the reverse spectrum spreading, and the duplication control information superimposed by the different processing is extracted from the main information signal. One information most closest to duplication prohibition is selected as an output duplication control information out of the plural extracted duplication control information. On the basis of the selected output duplication control information, the main information signal is controlled on duplication.
