Abstract
A bit buffer system wherein transmission data signals are sequentially stored in a shift register having a predetermined number of stages, the transmission data signal is taken out of a substantially central one of the predetermined number of stages at the time of initialization to be sent to a receiving unit, and the phase difference between the timing pulse controlling the period of the transmission data signal and the timing pulse controlling the operation of the receiving unit to select a specified stage of the shift register so as to take out the transmission data signal therefrom according to a detected phase difference. A specified code contained in the transmission coded data signal is detected to effect the initialization.
Claims10
In a bit buffer system wherein transmission data signals are sequentially stored in a shift register with a predetermined number of stages, the transmission data signal is taken out from a substantially central one of the predetermined number of stages of said shift register upon initialization to be sent to a receiving unit, the phase difference between the timing pulse controlling the period of said transmission data signal and the timing pulse controlling the operation of said receiving unit is detected to select a specified stage of said register so as to take out said transmission data signal therefrom according to a detected phase difference, the improvement which comprises means detecting a specified code contained in said transmission data signal for carrying out said initialization.
