Abstract
The applicability of MPEG video coding can be improved by scaling the algorithmic complexity and resource usage to the desired application and device. This paper presents a new DCT computation technique of which the quality and amount of computations is maximized for a limited number of operations. For halved computing resources, about 2-4 SNR dB improvement was obtained when compared to a diagonally oriented computation of coefficients, matching with the conventional MPEG scanning
