Abstract
PURPOSE:To establish the synchronization in a short time by forming >= one synchronizing signal among m-set of signals by code rule violation so as to superimpose the signal to a prescribed location in a frame in sending N-bit of data while it is divided into m-set of main frames each comprising M-bit. CONSTITUTION:The main frame M (bit 1024) is sent while being formed as a multi-frame of collection of m (=48)-set. A head bit F of 1st, 9th-41th main frames is formed by a bit of code rule violation V and the frame number of the relevant frame is superimposed by the code rule violation V onto the 2nd-7th bit data of each main frame. In allocating 2<0> to the 7th bit, 2<1> to the 6th bit -2<5> to the 2nd bit, the presence of the violation rule represents 1 and the absence of it shows 0. For example, in the case shown in figure, for example, the result is 1X2<0>+1(X)2<3>+1X2<5> and the number of the 41st main frame is detected easily to reduce the time of frame synchronization.
