Verfahren und Einrichtung zur Bewegtbilddecodierung.

摘要

For decoding animated images a processor processes luminance and chrominance information components, and a memory is used to store the corresponding information components relating to one or several images. First the digital data (DEC) are decoded and then the images (GEN) based on these data are generated. As far as the luminance is concerned, images are created by interpolation based on a preceding and a subsequent image. The interpolation (IM1) used for creating an image based on a preceding and subsequent image starts (G) before the end of decoding the luminance data of the subsequent image (Y2), and this interpolation starts after decoding half the number of luminance data of the subsequent image (D). The luminance data of an image of the row N (Y4) are replaced in the memory by those of the image of the row N+4 (Y8) as soon as half the image of the row N+1 (IM5) has been generated.
