| Abstract: | The applicability of MPEG video coding can be improved by scaling both the algorithmic complexity and resource usage, considering the desired application and device that is going to be used. This paper presents a new DCT computation technique of which both the quality and amount of computations is optimised 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. |
