ABSTRACT:
A video signal having a given line scan rate is converted to a different line scan rate by analog encoding such that each scan line is divided into a finite number of picture elements and video information corresponding to each picture element is modulated onto one of a series of carrier frequencies for transmission in parallel form. An inexpensive decoder scans the encoded video signal to reconstruct an output video signal having a line scan rate related to the rate of repetition of the encoded video signal scanning cycle.
