Complexity Reduction Techniques Applied to The Compression of High Definition Sequences in Digital TV

H.264/AVC is a hybrid predictive-transform coder. In this paper we propose a more computational efficient approach to implement the prediction module, its most complex stage. The idea is to employ a subset of dominant prediction modes instead of testing all modes recommended by H.264/AVC standard. Results show that, for high definition sequences, the quality loss is negligible allowing us to control the compression complexity of high definition video sequences. Keywords— H.264/AVC, mode decision, high-definition, reduced complexity.
