Zusammenfassung: | This invention discloses a method for concealing video error based on macro-block classification, including: obtaining a pixel number and column diagram of pixel of jumping point at the edge of a macro-block to be restored, judging whether the macro-block is a smooth block, edge block or complicated vein block; if it is the smooth block, then adopting the weighted average to restore; if it is theedge block, then adopting the minimum pixel span rule to restore; if it is the complicated vein block, then judging the pixel number of the edge jumping point in the complicated vein block, and judging the region divided by the edge jumping point as a smooth region and complicated vein region; adopting the weighed average to the smooth region to restore; selecting a pixel matching block most close to the pixel to be restored to the complicated vein region, using the pixel at the corresponding position in the pixel matching block to cover the pixel to be restored.
