Pixels in an uncompressed video frame are grouped into groups of pixels for wireless transmission from a transmitter to a receiver, wherein the neighboring pixels in each group possess (have) high spatial correlation. Upon receiving the pixel groups, the receiving station reconstructs the video frame from the received pixel groups, wherein upon detecting an erroneous pixel in a group, information from one or more neighboring pixels in that pixel group are used in place of the erroneous pixel. Further, FEC encoding is utilized recovering bit-errors.
