Abstract
An error concealment method and apparatus are provided. The error concealment method includes determining a reference direction of a lost frame by determining whether a scene change between frames has occurred based on the lost frame; extracting concealment reference points for a pixel of the lost frame by using at least one frame except for the lost frame according to the determined reference direction; obtaining a concealment pixel value of the pixel of the lost frame by giving weight values to the extracted concealment reference points; and restoring the lost frame by performing a concealment of the pixel using the concealment pixel value. According to the error concealment method and apparatus, when a frame loss occurs in an appliance that receives/outputs compressed moving images, error concealment in the unit of a frame can be effectively performed, and the deterioration of picture quality due to the error propagation can be minimized.
