<p>According to a method of this invention, information and check bits in one frame of information to be transmitted are divided into two fields (i.e., a first field (A) not requiring addition of fixed bits, and a second field (B) requiring addition of fixed bits). The characteristic inherent to the bit pattern formed of a sync signal (FP) and the second field (B) does not appear in the first field (A) so that the sync signal (FP) can be discriminated. The number of fixed bits inserted in one frame can thus be decreased, and transmission efficiency can be improved.</p> |
