Abstract
Digital transmission of uncompressed high-definition video is challenging because of its high data rate and its extreme sensitivity to bit errors. In this paper we propose a simple error correction scheme to reduce the bit error effects in the video at the receiver end of a wireless channel. Our scheme uses the large amount of spatial redundancy already present in uncompressed HD video data to provide an extra layer of protection in addition to that provided by channel coding. Thus, our method requires no change to the video signal being transmitted and is compatible with any existing solution for HD video transmission. Using simulations over a range of byte error rates, we show that our scheme effectively reduces the number of visible artifacts because of uncorrected channel errors, and provides approximately 7 dB improvement in peak signal to noise ratio.
