<p>A television receiver includes an MPEG decoder/decompressor (62-66) for providing decoded/decompressed pixel blocks. Decoded/decompressed pixels are recompressed prior to storage in frame memory (14). In the recompression process a reference first pixel is compressed as a function of a pixel block parameter. A reconstructed reference pixel value is used in a prediction network when reconstructing remaining pixels of the pixel block prior to display. A first pixel processor accurately compresses a reference pixel which prevents the propagation of a prediction error throughout the reconstructed block.</p> |
