摘要

Device under - temporal sampling and temporal interpolation in a sequence of interlaced images, comprising a circuit for the spatial prefiltering of the said sequence, of the circuits in - samplings, respectively, spatial and temporal, and a movement estimation stage. This device is applied to the embodiment of a coding device for transmission system, and to the embodiment of the corresponding decoding device, one and the other similar in structure that is - to - say comprising the same number of processing branches controlled by a circuit for deciding relative to the branch of the treatment to select. The various variants of coding devices to the compensation of movement can be supplemented by a circuit 1910 of direct temporal filtering in order to eliminate the residual defects such as jerks, thus be understood that the devices of the associated decoding, supplemented by a filtering circuit inverse temporal. / p & & p & application: high definition television.
