ABSTRACT:
A coding system for effecting band compression transmission of a binary signal such as a facsimile picture signal is disclosed. The coding system is characterized by converting each block of that binary coded m-ary digit which is associated with a length composed of a train of "0" of a binary signal into a code word having that order which corresponds to an original order of the m-ary digit which means the block in one of two groups and converting each block of that binary coded digit which is associated with a length composed of a train of "1" of said binary signal into a code word having that order which corresponds to the original order of the m-ary digit which means the block in another group.
