Abstract: A system and method are disclosed for efficiently determining a prediction block for a current block of interest in a video signal encoding protocol. In a preferred embodiment, this is achieved by determining whether there is a correlation between the intra 4×4 predictions and the 16×16 predictions. If the correlation to the 16×16 prediction modes is lower than a predetermined threshold value, then the additional prediction blocks using 16×16 intra luma prediction are not calculated. If the correlation to the 16×16 prediction modes is higher than the predetermined threshold value, then the additional prediction blocks are calculated using 16×16 intra luma prediction. A cost function may then be used to determine the predicted bit cost of each prediction block, and the prediction block with the lowest cost may be selected as the prediction block for the current block of interest.
