  • Patent number: 4060832
    Abstract: A digit rate reducing method in the transmission of video-telephone signals, wherein each frame is scanned by means of two consecutive fields comprising each the lines of same parity, each frame dot being represented by a word of n, in particular 3, binary digits comprising transmitting a frame every three frames, storing a frame of each parity at the receiving equipment in a frame storage device, systematically freshening-up a stored frame by the next transmitted frame of same parity, and regenerating intermediate frames by interpolating between the stored frames, further comprising forming a pseudo-field I.sub.n with opposite parity to a stored field T.sub.n by interpolating between T.sub.n and the stored field T.sub.n+3 or T.sub.n-3, and regenerating an intermediate field T.sub.n+1 or T.sub.n-1 from I.sub.n and T.sub.n+3 or T.sub.n-3, respectively.
