HEVC / H.265 Explained

The JCT-VC brings together image and video encoding experts from around the world, producing a single standard that is approved by two standards bodies;. HEVC was developed with the goal of providing twice the compression efficiency of the previous standard, H. Although compression efficiency results vary depending on the type of content and the encoder settings, at typical consumer video distribution bit rates HEVC is typically able to compress video twice as efficiently as AVC.

End-users can take advantage of improved compression efficiency in one of two ways or some combination of both ;. The initial version of the H. End-users can take advantage of improved compression efficiency in one of two ways or some combination of both ; At an identical level of visual quality, HEVC enables video to be compressed to a file that is about half the size or half the bit rate of AVC, or When compressed to the same file size or bit rate as AVC, HEVC delivers significantly better visual quality.

How can HEVC encode video files twice as efficiently as previous video coding standards? Most of the power of video compression standards comes from a technique known as motion compensated prediction. Blocks of pixels are encoded by making reference to another area in the same frame intra-prediction , or in another frame inter-prediction.

Where H. HEVC allows predicted blocks to be coded in different block sizes than the residual error. The residual from those predictions is then coded with a second quad-tree which can optionally have greater depth than the prediction quad-tree. HEVC can encode motion vectors with much greater precision, giving a better predicted block with less residual error.

There are 35 intra-picture directions, compared with only 9 for H. An improved deblocking filter Sample Adaptive Offset — an additional filter that reduces artifacts at block edges.

High Efficiency Video Coding

The overall amount of video data rate that is to be transferred over networks will continue to grow at a very fast pace, driven by the increased number of services and users and the increasing resolution of video from SD to HD and beyond. Market demands for video services with increasingly high quality temporal and spatial resolution, color fidelity, amplitude resolution continue to be evident, and video has become a major and continuously-increasing percentage of digital network traffic world-wide. It is difficult in the transmission networks of today to carry HDTV resolution with data rates appropriate for high quality to the end user — and this is especially the case on the Internet, where video-over-broadband services have now emerged a major phenomenon. According to various reports, video has become a majority of network traffic world-wide, and its traffic load continues to grow at a rapid pace. In the meantime, technology designs for substantial further improvement of video compression have begun to emerge.

High Efficiency Video Coding: Coding Tools and Specification

Brahmasury Jain 1 and K. Manuscript received on September 15, Accepted for publication on October 1, Published on November 15, In this paper a coding unit early termination algorithm resulting in a fast intra prediction is proposed that terminates complete full search prediction for the coding unit. This is followed by a prediction unit mode decision to find the optimal modes HEVC encoder 35 prediction modes. This includes a two-step process: firstly calculating the Sum of Absolute Differences SAD of all the modes by down sampling method and secondly applying a three-step search algorithm to remove unnecessary modes.
