BILDDATENPROZESSOR FÜR BILDSPEICHERSYSTEM MIT ERNEUTER KOMPRIMIERUNG |
摘要 |
A television receiver includes an MPEG decoder for providing decoded pixel blocks. Decoded pixels are recompressed prior to storage in frame memory. 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. |
