METHOD AND DEVICE FOR PROCESSING ERROR OF IMAGE DATA IN PACKET TRANSMISSION NETWORK, PARTICULARLY CONCERNED WITH DECIDING A DEGREE OF AN ERROR BY USING ERROR GENERATION POSITION IN ORDER TO MINIMIZE AN ERROR ACCUMULATION EFFECT OF AN IMAGE TERMINAL SYSTEM

摘要

Purpose: method and apparatus are arranged to decide whether that a mistake is sensed in block cabinet for handling a mistake of the pictorial data in a Packet Transport Network, when decoding an image, a wrong output position is determined, if mistake is sensed, so skip pictures, to minimize error accumulation effect. Construction: CODEC units decoding in macro block unit (S300) receives image, decides whether that a mistake is sensed (S302). If so, CODEC units determine a position of the block (S304) that a mistake generates. CODEC unit processes mistake is according to wrong output position (S306). If mistake is not felt, CODEC units use corresponding image to be decoded (S308) as the next image of reference images.
