INFORMATION PROCESSING APPARATUS AND DUPLEX TRANSMISSION METHOD
First Claim
1. An information processing apparatus comprising:
- a first module; and
a second module,wherein the first module includes;
a first data signal producing unit that produces a first data signal by coding a first transmitted data into a waveform, the waveform not including a direct-current component, a polarity of the waveform being inverted in each half period of a clock;
a first signal sending unit that sends the first data signal to a second module; and
a signal subtracting unit that subtracts the first data signal from a signal received from the second module, andthe second module includes;
a clock detecting unit that detects the clock based on the polarity inverting period of the first data signal received from the first module;
a second data signal producing unit that produces a second data signal by coding a second transmitted data into a waveform using the clock detected by the clock detecting unit, the waveform not including the direct-current component; and
a second signal sending unit that sends the second data signal to the first module while the second data signal is synchronously added to the first data signal sent from the first module.

Abstract
There is provided an information processing apparatus includes a first module and a second module. The first module includes a first signal generator that produces a first signal by coding a first transmitted data into a waveform not including a direct-current component, having a polarity being inverted in each half period of a clock; a first signal sending unit that sends the first signal; and a signal subtracting unit that subtracts the first signal from a received signal. The second module includes a clock detecting unit that detects the clock based on the polarity inverting period of the first signal received from the first module; a second signal generator that produces a second signal by coding a second transmitted data into a waveform not including the direct-current component; and a second signal sending unit that sends the second signal while the second signal is synchronously added to the first signal.

7. A duplex transmission method, comprising the steps of:
-
producing a first data signal by coding a first transmitted data into a waveform using a first module, the waveform not including a direct-current component, a polarity of the waveform being inverted in each half period of a clock; sending the first data signal to a second module using the first module detecting the clock using the second module based on the polarity inverting period of the first data signal received from the first module; producing a second data signal by coding a second transmitted data into a waveform with the clock detected by the clock detecting unit using the second module, the waveform not including the direct-current component; sending the second data signal to the first module using the second module while the second data signal is synchronously added to the first data signal sent from the first module; and extracting the second data signal by subtracting the first data signal from the signal received from the second module using the first module.
