VIDEO SIGNAL PROCESSING CIRCUIT

摘要

The video encoding/decoding circuit comprises; a decimation circuit decimating the input video signal by the factor of 1/M; a horizontal/vertical interpolating circuit interpolating the processed video signal by the factor of M; an encoder eliminating DC components by subtracting the output of a delay circuit and a horizontal interpolation circuit; a decoder reconstructing the original signal by adding the output of the delay circuit and the horizontal interpolation circuit.
