Abstract:
A game device comprising:a peripheral port adapted to be connected to at least one peripheral device via a data transmission path contained therein and to receive and transmit data which is allocated in a first data signal and a second data signal, said first and second data signals being arranged in data frames;one data frame of said first and second data signals including a start pattern, a data pattern and an end 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 first train of pulses;said data pattern having a data format including a first clock signal in said first data signal and a second clock signal in said second data signal and data to be transmitted to said peripheral device being divided into a first data sequence and a second data sequence and added respectively to said first and second clock signals by inserting in order each bit of the first data sequence respectively between pulses of said first clock signal and by inserting in order each bit of the second data sequence respectively between pulses of said second clock signal, said second clock signal having the same frequency as, and a phase difference from, said first clock signal 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;wherein said game device transmits said data frame containing said start pattern, said data pattern and said end pattern as a transmission unit to said at least one peripheral device.
