Abstract :
This study presents a signal restoration method in a block-coded still image and video, to cope with a block-loss problem at a decoder arising from an imperfect transmission through a communication channel. The feature of the proposal is that it applies a two-dimensional error correction coding technique not to the bit stream error correction, but to the signal restoration at the image plane
