Abstract: A signal compression system for efficient transmission of an input binary digital signal, in the form of a binary pulse signal, in which bit polarity reversal is checked after sampling for a predetermined number of bits of the sampled binary pulse signal. In a case of detection of any bit polarity reversal, the sampled binary pulse signal is sent out into a converted output pulse signal for the predetermined number of bits. In a case of non-detection of any polarity reversal, the number of bits or the number of bit blocks having no polarity reversal is coded as a coded pulse signal and sent out into the converted output pulse signal. A coded pulse signal is distinguished, the the converted output pulse signal, from the binary pulse signal by at least one flag bit.

Abstract: A system for coding two-dimensional information of M lines and N columns, in which two-dimensional information of M lines and U columns is predetermined as a basic block. If any column information in the basic block has an information change with respect to column information immediately preceding it, information in the basic block is coded. If each column information in the basic block has no information change with respect to the column information immediately preceding it, information corresponding to the number of columns of the basic block and the number of subsequent columns having no information change is coded. Two-dimensional information obtained after the computation operation of a correlation function between an instant bit of information and an immediately preceding bit of information in at least either of the line direction and the column direction may be applied as the input of this system. If the entire information of one line does not include any information change with respect to the information immediately preceding it, the number of lines preceding a line including an information change may be coded before the above mentioned coding.
