Review for High Efficiency Video Coding (HEVC)

2014 IEEE Conference on Systems, Process and Control (ICSPC 2014), 2014
A new standard of video compressing has been developed by ISO and ITU-T and this standard is known as High Efficiency Video Coding (HEVC) or H.265. In January 2013, HEVC has received the first approval. By comparison with the predecessors coding standers, HEVC doubles the compression ratio of data with maintains the quality level of video.

The New High-Efficiency Video Coding Standard

SMPTE Motion Imaging Journal, 2013
Recent developments in camera and display technologies are supporting increasingly larger resolutions. At the same time, studies predict that the share of video data in overall consumer Internet traffic will become larger than 75%. These developments require a more efficient coding of digital video than the current video-coding standard H.264/ MPEG-4 ...

Simplified AMVP for High Efficiency Video Coding

2012 Visual Communications and Image Processing, 2012
In High Efficiency Video Coding (HEVC), advanced motion vector prediction (AMVP) is adopted to predict current motion vector by utilizing a competition-based scheme from a given candidate set, which include both the spatial and temporal motion vectors. In order to enhance the practicability of the AMVP, a simplified AMVP is proposed.

Energy-efficient multimedia systems for high efficiency video coding

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
This paper presents a cross-layer approach for analyzing and designing energy-efficient advanced multimedia systems with next-generation High-Efficiency Video Coding (HEVC) standard. Our approach leverages both algorithmic and architectural layers of system design abstractions in order to achieve a high power/energy efficiency.

Quantization Matrix Coding for High Efficiency Video Coding

2012
Quantization matrix (QM) has been adopted in image coding standards such as JPEG and JPEG-2000, as well as in video standards such as MPEG2, MPEG4 and H.264/AVC. QM can improve the subjective quality through frequency weighting on different frequency coefficients.

Efficient Rate Control for Intra-Frame Coding in High Efficiency Video Coding

Proceedings of the 11th International Conference on Signal Processing and Multimedia Applications, 2014
In this paper, a coding tree unit (CTU)-level rate control (RC) scheme is proposed for intra-frame coding in the high efficiency video coding (HEVC). The CTU-level target bits are allocated based on the content complexity and the parameters of the Cauchy-based rate-quantization (R-Q) model of the current CTU is estimated according to the neighboring ...

Efficient rate control for intra-only coding in high efficiency video coding

2013 Ninth International Conference on Natural Computation (ICNC), 2013
In this paper, a unified rate-quantization (R-Q) model is proposed for intra coding frame in High Efficiency Video Coding (HEVC). The adaptive rate control (RC) for intra-only coding temporal structure is developed based on the unified rate estimation model.
