Abstract:
A peripheral device which sends information required for a game to a game device, comprising:a transmission path including a connector arranged to connect said transmission path to said game device,said game device and said peripheral device being arranged to interactively transmit data including plural data bits to one another via said transmission path in accorance with a data-transmission format wherein the data is transmitted by allocating the plural data bits of the data alternately into a first data signal and a second data signal,said data-transmission format including, as one data frame, a start pattern, a data pattern and an end pattern, the start pattern preceding the data pattern and the end pattern following the data pattern,said start pattern having a data format wherein, while said first data signal transmits a constant potential level, said second data signal transmits a train of pulses;said data pattern having a data format including a first sequence of clock pulses in said first data signal and a second sequence of clock pulses in said second data signal and the plural data bits of the data to be transmitted being alternately allocated in order in said first data signal and said second data signal in a manner such that each bit in a first group of the data including every other bit of the data is inserted in order between pulses of said first sequence of clock pulses and each bit in a second group of data including every other bit of the data that is not in the first group of data is inserted in order between pulses of said second sequence of clock pulses, said second sequence of clock pulses having the same cycle period as, and a phase difference from, said first sequence of clock pulses so that a data bit in one of said first and second data signals is located at a timing corresponding to a clock signal component of a clock pulse in the other of said first and second data signals;said end pattern having a data format wherein, while said second data signal transmits a constant potential level, said first data signal transmits a second train of pulses.
