05089889 is referenced by 96 patents and cites 7 patents.

An inter-frame predictive encoding apparatus which derives a prediction error signal representing successive frames of a video signal based on differences between pixel data of each frame and pixel data of at least one other frame, and executes intra-frame encoding of the prediction error signal, in which the prediction error signal is transferred through a spatial filter prior to intra-frame encoding, and in which the degree of filtering is controlled fixedly or varying in units of frame intervals by a control signal, for thereby controlling the high frequency components of the error signal to an appropriate level in accordance with respective requirements for the output data rate from the apparatus and spatial resolution of a finally obtained picture.
