Abstract
The video RAM requisite of an MPEG-2 decoder is reduced by recompressing according to an adaptive pulse code modulation scheme (ADPCM) at least the I and P pictures, after MPEG-2 decompression and before storing the relative data in the video RAM. The ADPCM recompressed and coded data written in the video RAM are decoded and decompressed during the reconstruction of a B-picture to be displayed.
