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.

Description

[0001] This application claims Korean Patent Application No. 10-2005-0082858 filed with the Korean Intellectual Property Office on September 6, 2005 and U.S. Provisional Patent Application No. 60 / 694,998 filed with the United States Patent and Trademark Office on June 30, 2005 priority, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Methods and apparatus consistent with the present invention relate to error concealment, and more particularly to error concealment that can improve the picture quality of video data by concealing frame loss and reducing error propagation. Background technique [0003] With the increase in the transmission of moving images in the radio network environment, the development of radio network technology has also made rapid progress. Currently, techniques for compressing such moving image frames have been extensively researched and developed. Frame ...
