HEVC: The New Gold Standard for Video Compression: How Does HEVC Compare with H.264/AVC?
TLDR
In this paper, the Joint Collaborative Team on Video Coding (JCT-VC) was established with the objective to develop a new high-performance video coding standard for mobile applications.Abstract:
Digital video has become ubiquitous in our everyday lives; everywhere we look, there are devices that can display, capture, and transmit video. The recent advances in technology have made it possible to capture and display video material with ultrahigh definition (UHD) resolution. Now is the time when the current Internet and broadcasting networks do not even have sufficient capacity to transmit large amounts of HD content-Let alone UHD. The need for an improved transmission system is more pronounced in the mobile sector because of the introduction of lightweight HD resolutions (such as 720 pixel) for mobile applications. The limitations of current technologies prompted the International Standards Organization/International Electrotechnical Commission Moving Picture Experts Group (MPEG) and International Telecommunication Union-Telecommunication Standardization Sector Video Coding Experts Group (VCEG) to establish the Joint Collaborative Team on Video Coding (JCT-VC), with the objective to develop a new high-performance video coding standard.read more

Fast PU decision algorithm based on texture complexity in HEVC
TL;DR: A fast PU decision algorithm is proposed that can greatly reduce the coding complexity by averagely up to 45% in the random access configuration with only 2% bit-rate increment and a 0.08db PSNR decrement compared to the one of original HEVC encoder.

Intra-Refresh and Data-Partitioning for Video Streaming over IEEE 802.11e
TL;DR: This chapter demonstrates a wireless access scheme that selectively drops packets that carry intra-refresh macroblocks, and shows that, when congestion occurs, it is possible to gain up to 2 dB in video quality over assigning a stream to a single IEEE 802.11e access category.

A Novel Chroma Processing Scheme for Improved Color Accuracy of HDR Video Content
Maryam Azimi,Mahsa T. Pourazad +1 more
TL;DR: This work proposes a chroma processing scheme that reduces the color errors generated by the quantization and subsampling processes in the HDR video delivery pipeline by using the de-correlated color space of ICtCp and re-distributes chroma code-words in favor of those colors that the authors' eyes are most sensitive to.

Towards jointly optimal spatial prediction and adaptive transform in video/image coding
TL;DR: This paper proposes a new approach to combined spatial (Intra) prediction and adaptive transform coding in block-based video and image compression, which is implemented within the H.264/AVC intra mode, and is shown in experiments to significantly outperform the standard intra modes, and achieve significant reduction of the blocking effect.

One-pass encoding algorithm for adaptive loop filter in high-efficiency video coding
TL;DR: A method to estimate filtering distortion without performing real filter operation is proposed for adaptive loop filter in high-efficiency video coding (HEVC) and the number of encoding passes can be effectively reduced from 16 to 1.
