Abstract: An orthogonal frequency division multiplexed signal generator comprises a data sequence conversion means, a power changing means, an inverse discrete Fourier transform part, and an orthogonal modulation means, and modulates a first data and a second data using modulation systems independent of each other, into an orthogonal frequency division multiplexed signal. The data sequence conversion means arranges the first data to be transmitted, in a predetermined order correspondingly to two or more sub-carriers orthogonal to each other on a frequency axis. The power changing means changes powers of the sub-carriers in accordance with the second data to be transmitted which is independent of the first data. The inverse discrete Fourier transform means generates a time-base waveform by synthesizing the individual sub-carriers. The orthogonal modulation means performs orthogonal modulation on a real axis signal and an imaginary axis signal which are orthogonal to each other to synthesize them.

Abstract: In a network system, clock signals of a server device and a client device are synchronized with each other without having any influence of a change and a delay of the transmission time of data. Therefore, in the network system in which the client device receives and reproduces information transmitted from the server device, the server device counts the number of clock pulses of a server clock signal used to compress and encode information on the basis of a power source synchronous pulse signal synchronized with a power source frequency. The server device outputs information showing the counted clock pulse number and the compressed and encoded information to the client device. The client device counts the number of clock pulses of a client clock signal used to decode and decompress the compressed and encoded information on the basis of the power source synchronous pulse signal synchronized with the power source frequency.
