Abstract
The present invention uses large intra blocks coding for uniform regions of the video by making early decision of intra block coding based on DCT and DC calculations. This has shown to increase the visual quality of uniform areas significantly, and by utilizing a possibility of parallel calculation, the extra processing cost for the early decision is insignificant.
