There is an increasing need in bandwidth requirements, particularly, due to the increase in the device resolution [1]. As a result, there is a strong demand to decrease the video transmission bitrate without reducing visual quality. In 2010, a Joint Collaborative Team on Video Coding (JCT-VC) was established by ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Pictures Expert Group (MPEG) to work on the video coding standard, which was called the High-Efficiency Video Coding standard, or HEVC in short. The H.265/MPEG-HEVC video coding standard [2] was approved in 2013 (see Figure 1), and it provides approximately 50% coding gain compared to its predecessor H.264/MPEG-AVC [3],[4].
