High Efficiency Video Coding (HEVC) is the latest attempt by ISO/MPEG and ITU-T/VCEG to define the next generation compression standard beyond H.264/MPEG-4 Part 10 AVC. One of the major goals of HEVC is to provide efficient compression for resolutions beyond HDTV. However, the subjective evaluations that led to the selection of technologies were bound to HDTV resolution. Moreover, performance e...

The status of high efficiency video coding development is reviewed based on public available documents in HEVC version 4 standardization process. Here, the requirements and results of call for proposals on screen content coding (SCC) tools for HEVC are presented. The most significant additional coding tools are highlighted. To achieve high coding efficiency in SCC-HEVC, new coding tools that ex...

1. Trends of HEVC Standardization The target of HEVC standardization is to substantially surpass the compression efficiency of the existing MPEG-4 AVC/H.264 international standard,(1) which currently provides the highest compression performance. The expected complexity of HEVC must be an acceptable level for the hardware technology when supported products are put on the market. In the standardi...

This chapter provides an overview of the design challenges faced in the implementation of hardware HEVC decoders. These challenges can be attributed to the larger and diverse coding block sizes and transform sizes, the larger interpolation filter for motion compensation, the increased number of steps in intra prediction and the introduction of a new in-loop filter. Several solutions to address ...

High efficiency video coding (HEVC) seeks the best code tree configuration, the best prediction unit division and the prediction mode, by evaluating the rate-distortion functional in a recursive way and using a "try all and select the best" strategy. Further, HEVC only supports context adaptive binary arithmetic coding (CABAC), which has the disadvantage of being highly sequential and having st...

The emerging High Efficiency Video Coding (HEVC) standard provides equivalent subjective quality with about 50% bit rate reduction compared to the H.264/AVC High profile. However, the improvement of coding efficiency is obtained at the expense of increased computational complexity. This paper presents a fast intra-encoding algorithm for HEVC, which is composed of the following four techniques. ...

Depth coding in 3D-HEVC for the multiview video plus depth (MVD) architecture (i) deforms object shapes due to block-level edge-approximation; (ii) misses an opportunity for high compressibility at near-lossless quality by failing to exploit strong homogeneity (clustering tendency) in depth syntax, motion vector components, and residuals at frame-level; and (iii) restricts interactivity and lim...

As the extension of high efficiency video coding (HEVC) standard, three dimensional-HEVC (3D-HEVC) is latest 3D standard. 3D-HEVC adopts many complicated algorithms to generate additional intermediate views for representation, which result in extremely complexity. Therefore, this paper proposed a fast depth intra approach reduce complexity, based on convolutional neural network (CNN). First, we...

As the successive video compression standard of H.264/AVC, High Efficiency Video Codec (HEVC) will play an important role in video coding area. In the deblocking filter part, HEVC inherits the basic property of H.264/AVC and gives some new features. Based on this variation, this paper introduces a novel dual-mode deblocking filter architecture which could support both of the HEVC and H.264/AVC ...

A multi-layer authentication scheme for HEVC compressed video is proposed. The combination of CU sizes, which is unique to HEVC and sensitive to video manipulation, is considered along with other elements in the HEVC coding standard to generate the authentication tag. Temporal dependency was enforced, where the authentication tag generated in one slice is embedded into its subsequent slice. By ...
