ABSTRACT:
A scan rate converter utilizing a discrete differential coding system as disclosed. The scan rate converter converts input FSTV and SSTV video information into discrete differential coded signals and stores these signals in a high speed memory. The stored video information is read out of the high speed memory at both a fast scan and a slow scan rate and is reconverted into respective FFST and SSTV output signals.
