The advanced video encoder High Efficiency Video Coding (HEVC) utilizes several novel coding tools so that it can obtain improvement in coding performance for a huge number of video data. However, these tools increase the computational complexity greatly specially in the interprediction phase. Therefore, optimization for interprediction plays an important role in accelerating the whole HEVC enc...

The paper presents analysis of frame partitioning in the next generation video coding standard HEVC. Complex study on frequency of the particular coding unit, prediction unit and transform unit sizes selection made by the encoder compliant with HEVC technology is included. General conclusions based on extensive experiments for HD video sequences are presented. Such knowledge may be the first st...

Hypothetical Reference Decoder is a hypothetical decoder model that specifies constraints on the variability of conforming network abstraction layer unit streams or conforming byte streams that an encoding process may produce. High Efficiency Video Coding (HEVC) builds upon and improves the design of the generalized hypothetical reference decoder of H.264/ AVC. This paper describes some of the ...

In this paper, an improved low complexity algorithm for 3D-HEVC is proposed to reduce the computational complexity. The basic idea of the method is to utilize the boundary homogeneity of texture and depth map which is generated by Laplacian filter. Firstly, based on the evaluation result of the boundary homogeneity, an early coding unit (CU) decision method is proposed to achieve the low comput...

With the development of Internet and video capture techniques, videoconferencing becomes still more popular. However, with the increased size of the video resolution, the volume of the raw videoconferencing video data increases dramatically. The H.265/HEVC video compression standard can efficiently compresses the videoconferencing video, while the high compression rate is at the cost of heavy e...

It has only been a handful of years since AVC/H.264 ran riot through the video delivery chain and enabled a range of cross-device and cross-network services to bloom and flourish. With the imminent publication of the HEVC/H.265 video coding standard from ITU-T VCEG and ISO/IEC MPEG enabling a similar breakthrough in relative bit-rate reduction, we are poised for potentially the fastest embraced...

HEVC achieves significant coding efficiency improvement which is the best choice of 3D content but at a cost of much higher computation complexity. We propose a prediction estimation based H.264 to HEVC intra transcoder which can reach the high speed up for CU splitting with minor loss of coding efficiency for Intra picture. Our proposed method uses not only the intra prediction mode, predictio...

In the Differential Pulse-code Modulation (DPCM) image coding, the intensity of a pixel is predicted as a linear combination of a set of surrounding pixels and the prediction error is encoded. In this paper, we propose the adaptive residual DPCM (ARDPCM) for intra lossless coding. In the ARDPCM, intra residual samples are predicted using adaptive mode-dependent DPCM weights. The weights are est...

The most essential part of almost all video coding standards such as H.262/MPEG-2, H.264/MPEG-4 and newly emerged High Efficiency Video Coding (H.265/HEVC) is Motion Estimation. HEVC provides better performance in compression and efficiency in coding for Beyond HD and UHD videos. The main drawback is its computationcomplexity. The complexity is mainly due to Motion Estimation (ME), as it consum...

High-efficiency video coding (HEVC) is a new video coding standard being developed by the Joint Collaborative Team on Video Coding. HEVC adopted numerous new tools, such as more flexible data structure representations, which include the coding unit (CU), prediction unit, and transform unit. In the partitioning of the largest coding unit (LCU) into CUs, rate distortion optimization (RDO) is appl...
