The use of multiresolution (MR) joint source-channel coding in the context of digital terrestrial broadcasting of high definition television (HDTV) is shown to be an efficient alternative to traditional single-resolution techniques. While the single-resolution schemes suffer from a sharp threshold effect in the fringes of the broadcast area, we show how a matched multiresolution approach to both source and channel coding can provide a stepwise graceful degradation. Furthermore, this… CONTINUE READING
