Patent ID: 8619898

Claim:
An information processing apparatus, comprising: a signal receiving unit that receives a signal encoded in such a way that the signal containing a first bit value and a second bit value that are mutually different, wherein the first bit value is represented by a plurality of first amplitude values, the second bit value is represented by a second amplitude value that is different from the first amplitude values, a same amplitude value is not taken successively, and polarities of the amplitude values are reversed in each period; an amplitude square unit that squares amplitude values of the signal received by the signal receiving unit; an input data decoding unit that decodes an input data by determining the first and second bit values based on the squared amplitude values; and a clock component detection unit that detects a clock component of the signal by comparing the amplitude values of the signal before being squared with a predetermined threshold value, wherein the clock component detection unit detects the clock component without referencing a reference clock signal.
