A scalability extension design is proposed to the upcoming High Efficiency Video Coding (HEVC) standard, to support spatial and SNR scalability. The design attempts to minimize changes needed for the enhancement layer codec from the single layer HEVC codec, re-using existing tools exactly wherever possible.

SPIE Proceedings, 2012
HEVC is the new video coding standard developed in a joint effort (JCT-VC) by ISO MPEG and ITU-T VCEG. As other state-of-the-art block-based inter-prediction codec, it is very sensitive to illumination variations in-between frames. To cope with this limitation, the weighted prediction (WP) tool has been proposed.

Complexity-scalable HEVC encoding
2016 Picture Coding Symposium (PCS), 2016HEVC encoders impose several challenges in resource-constrained embedded applications, especially under real-time and battery constraints. This paper proposes a complexity-scalable encoder that is able to achieve considerable time savings while maintaining an efficient rate-distortion-complexity tradeoff.

This chapter provides background about Three-Dimensional High Efficiency Video Coding (3D-HEVC) depth map encoding. Initially, the 3D-HEVC encoding structure is defined, relating its frame to a quadtree-like structure. The algorithms used in the intra-frame prediction of depth maps are described in detail, allowing a comparative understanding regarding

HEVC and VP9 are the current state-of-the-art in video compression, thus, it is expected that in the near future these new codecs will replace their predecessors. However, the process of converting video contents compressed with one standard to those using another standard is highly computationally expensive, since a priori the video contents must be ...

High Efficiency Video Coding(HEVC)
2013HEVC the latest standard is presented. Comparison with H.264/AVC ( Chap. 4) is cited. The focus is on overview of HEVC rather than a detailed description of tools and techniques that constitute the encoder. A plethora of projects listed at the end challenges the implementation and futher research related to HEVC.

Spatially Scalable Video Coding For HEVC
IEEE Transactions on Circuits and Systems for Video Technology, 2012Spatially scalable video coding (SSVC) provides an efficient way to transmit one video at different resolutions. Based on the emerging High Efficiency Video Coding (HEVC), we propose an SSVC scheme to support both single-loop (SL) and multiloop (ML) solutions by enabling different interlayer prediction mechanisms. Specifically, we employ two interlayer

Quadtree Degeneration for HEVC
IEEE Transactions on Multimedia, 2016The quadtree is one of the most advanced techniques contributing to the excellent compression performance of high efficiency video coding (HEVC). However, the computational complexity increases because the quadtree examines all coding unit (CU) sizes to obtain the optimal CU partitioning.

State of HEVC Bitrates in 2014: Comparing HEVC, H.264, and MPEG-2
SMPTE Motion Imaging Journal, 2014This paper presents the results of empirical testing of high-efficiency video coding (HEVC) for standard-definition (SD), high-definition (HD), and ultra-high-definition (UHD), including data from hundreds of encoding tests across a variety of bitrates.

Fast Motion Estimation Algorithm for HEVC
2012 IEEE Second International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2012Motion Estimation is an essential process in many video coding standards like MPEG-2, H.264/AVC and HEVC. Despite Motion Estimation has been used at the encoder, it is expected to be used in future consumer devices in the distributed video coding architectures. But the Motion Estimation itself consumes more than 50% coding complexity or time to encode.
