Abstract
A system () for encoding an input video frame (), for transmitting or storing the encoded video and for decoding the video is disclosed. The system () includes an encoder () and a decoder () interconnected through a storage or transmission medium (). The encoder () includes a turbo encoder () for forming parity bit data from the input frame () into a first data source (), and a sampler () for down-sampling the input frame () followed by intraframe compression () to form a second data source (). The decoder () receives data from the second data source () to form an estimate for the frame (). The decoder () also receivers the parity bit data from the first data source (), and corrects errors in the estimate by applying the parity bit data to the estimate. Each bit plane is corrected in turn by a turbo decoder (). The decoder determines how reliably a pixel value was decoded, too. Frame reconstruction module () takes advantage of this and discards unreliably decoded pixels and replaces them with predicted pixel values.
