Preface
In the last decades, the rapid advances of semiconductor technologies fostered a large development in the field of multimedia systems, mainly due to the continuous increase of computational resources and the availability of reliable communication infrastructures. Several video compression standards have been developed in this period, aiming at reducing transmission bit rates without decreasing the video quality. The High-Efficiency Video Coding (HEVC) standard, recently launched by the Joint Collaborative Team on Video Coding (JCT-VC), is the state of the art in video compression and is expected to gradually substitute its predecessor, the H.264/AVC standard. HEVC provides improved compression ratios in comparison to previous standards, but such gains are associated with large increases in the encoding computational complexity and consequently longer
