Abstract
There is provided an information processing apparatus including a data encoding unit that generates an encoded signal by encoding first input data based on CMI (Coded Mark Inversion) coding rules and encoding second input data using errors of the CMI coding rules, a clock signal addition unit that generates a transmission signal by synchronously adding a clock signal having an amplitude value larger than that of the encoded signal to the encoded signal generated by the data encoding unit, and a signal transmission unit that transmits the transmission signal generated by the clock signal addition unit.

An information processing apparatus, comprising:
- a data encoding unit that generates an encoded signal by encoding first input data based on CMI (Coded Mark Inversion) coding rules and encoding second input data using errors of the CMI coding rules;
- a clock signal addition unit that generates a transmission signal by synchronously adding a clock signal having an amplitude value larger than that of the encoded signal to the encoded signal generated by the data encoding unit;
- and
- a signal transmission unit that transmits the transmission signal generated by the clock signal addition unit.
An encoding method comprising the steps of:
- generating an encoded signal by encoding first input data based on CMI (Coded Mark Inversion) coding rules and encoding second input data using errors of the CMI coding rules;
- and
- generating a transmission signal transmitted through a predetermined transmission line by synchronously adding a clock signal having an amplitude value larger than that of the encoded signal to the encoded signal generated in the encoding step.
A signal transmission method comprising the steps of:
- generating an encoded signal by encoding first input data based on CMI (Coded Mark Inversion) coding rules and encoding second input data using errors of the CMI coding rules;
- generating a transmission signal by synchronously adding a clock signal having an amplitude value larger than that of the encoded signal to the encoded signal generated in the encoding step;
- transmitting the transmission signal generated in the clock addition step;
- receiving the transmission signal via a predetermined transmission line;
- detecting a clock component contained in the transmission signal based on a reversal period by detecting the reversal period of polarity held by the transmission signal received in the signal receiving step;
- and
- decoding the first and second input data by using the clock component detected in the clock component detection step.
