MATCHING CIRCUIT DEVICE BETWEEN TWO VIDEO PROCESSORS HAVING DIFFERENT RESOLUTIONS

摘要

A method of transforming serial binary data exchanged between facsimile transceivers having different horizontal resolutions. Binary signal elements representing a scanning line are separated into a sequence of n bit data words and the number and type of subsequent bit changes within each data word is derermined. A conicident sequence of m bit data words is generated such that the bit pattern of each corresponding n bit data word substantially is reproduced by arbitrarily padding of an insignificant bit if nm; wherein n:m corresponds to the ratio of the transceiver resolutions. The serial data stream is reproduced from the sequence of said second data words and transmitted to the receiving facsimile transceiver for recording.
