An encoder for digital video signals uses averages of pairs of transmitted samples to reconstruct untransmitted samples. The pair selected for reconstruction is selected in accordance with the criteria of least change around the untransmitted sample. If a plurality of averages are tied for least change, a priority order is used to select which average to use. For color video the priority order is preferably the horizontal, diagonal and vertical averages. A different order can be used for monochrome signals.
