Patent ID: 8279747

Claim:
An information processing apparatus, comprising: an encoding section for encoding a bit string to generate a data signal having an amplitude of a 1 and a transmission speed of b; a signal generation section synchronously adding a clock having a frequency of b/K (K is a predetermined natural number), an amplitude of a 2 (>a 1 ), and a smaller duty ratio than that of a bit-clock of the data signal to the data signal generated by the encoding section to generate a transmission signal, wherein the clock is a three-level clock having successive clock pulses that alternate in polarity; and a signal transmission section for transmitting the transmission signal generated by the signal generation section, and wherein the transmission signal generated by the signal generation section is one packet of a series of packets, the clock pulses alternate in polarity on a packet-by-packet basis, and the duration of each clock pulse is less than the duration of a packet.
