Abstract
An efficient high quality video coding and decoding technique is described. A prediction block is generated that contains modified coefficients. The modified coefficients improve the efficiency of the compression process once the prediction block is subtracted from the original block to generate a residual signal for quantisation and encoding. A similar process operates at the decoder side. The processes may operate in both the frequency and the spatial domain.
