Video is being watched more than ever before. It is estimated that in 2020, 82% of global IP traffic and 79% of global Internet traffic will come from video; globally 3 trillion minutes (5 million years) of video content will cross the Internet each month. According to the Cisco 2020 Forecast, that is one million minutes of video streamed or downloaded every second [1] . The rapidly increasing consumption of storage capacity and transmission bandwidth from video, especially HD and UHD video content, has made video compression a critical stage to guarantee the quality of delivery and playback.
