Paper Abstract

The hybrid coding scheme is modified. The discrete cosine transform used for encoding displaced frame differences is replaced by a predefined set of transform matrices based on autoregressive models up to the fourth order. The autoregressive models are parameterized using reflection coefficients. It is shown that the coding efficiency can be improved though side information for the chosen transform has to be transmitted to the decoder.
