Abstract
The invention relates to a method of reconstructing pixel values of a video frame for concealing corrupted pixel values. The method comprising receiving, by a receiving unit, of a signal from a communication channel and delivering by the receiving unit of video packets comprising pixel values possibly corrupted with errors; associating confidence levels with pixel values comprised in the video packets as delivered by the receiving unit; and reconstructing pixel values usable for display from the received pixel values, wherein a reconstructed value for a given pixel is obtained from the received values of a set of pixels, including the given pixel, weighted by their associated confidence levels.The invention allows for better reconstruction of corrupted pixel values and reduces the perceived distortion when displaying the video frame.
