A TEMPORAL ERROR CONCEALMENT METHOD IN THE H.264/AVC STANDARD

摘要

The present invention relates to a method of taking into consideration the nature of the H.264 / AVC coding standard enacted by the video standards, such as terrestrial and satellite DMB perform error concealment o'clock position, in particular including a macroblock in H.264 / AVC by performing an error concealment in using a variety of variable-size information, to a o'clock error concealment method in H.264 of a less amount of calculation while the defined range to provide improved image quality objective. ; Configuration means for constituting o'clock error concealment method according to the present inventions are H.264, confirming the four macroblock modes located at the sides of the lost macroblock, the predetermined using the checked macroblock modes sides determining an error concealment mode, with the number and size, according to the determined error concealment mode to calculate the cost value of the motion vectors and reference frame information in OBMA method characterized in that made in a step of performing error concealment do. ; H.264, error concealment
