This article first presents a combination of simple techniquesthat produce an extremely effective concealment method thatmaintains spatially correlated edges throughout any lost data; thisin turn gives an increase in both mathematical and visualperformance when compared with the commonly used bilinearconcealment technique. Secondly, this article looks at analternative use of the bilinear passive error concealment algorithmthat is often used by H.264 decoders. Occasionally, a concealedmacroblock is mathematically closer to the original than an encodedand decoded one. Thus, by removing these macroblocks from thestream at the encoder and thus forcing the decoder to conceal themissing data, a significant reduction in the bit stream size (up to5%) can be achieved with negligible loss in quality.
