In modern medical communication systems, the high-efficiency video compression technology is of great significance to the storage and transmission of digital medical videos. To further improve the compression performance of the medical ultrasound videos, two innovative technologies based on diagnostic region-of-interest (ROI) extraction with the High Efficiency Video Coding (H.265/HEVC) standar...

This paper presents a novel method for the real-time protection of new emerging High Efficiency Video Coding (HEVC) standard. Structure preserving selective encryption is being performed in CABAC entropy coding module of HEVC, which is significantly different from CABAC entropy coding of H.264/AVC. In CABAC of HEVC, exponential Golomb coding is replaced by truncated Rice (TR) up to a specific v...

As a successor to the H.264/Advance Video Coding (AVC), High Efficiency Video Coding (HEVC) is invented to get more compression and high quality video. But HEVC increases the complexity of video coding. To reduce this complexity various methods are proposed with different approach which also enhance the video compression and quality of video. This paper contains different techniques for video t...

This study evaluates the performance of the three latest video codecs H.265/MPEG-HEVC, H.264/MPEGAVC and VP9. The evaluation is based on both subjective and objective quality metrics. The assessment metric Double Stimulus Impairment Scale (DSIS) is used to evaluate the subjective quality of the compressed video sequences. The Peak Signal-to-Noise Ratio (PSNR) metricis used for the objective eva...

Context-based adaptive binary arithmetic coding (CABAC) is a single entropy coding mode of the newest video coding standard, High Efficiency Video Coding (HEVC). Despite the high coding efficiency of CABAC, its data dependencies prevent effective parallelization, which also means limited throughput. Accordingly, during the HEVC standardization activity of entropy coding, both coding efficiency ...

In this paper, a rate control scheme is proposed based on a new rate-quantization model for emerging HEVC video codec. Unlike conventional video codecs, the HEVC has hierarchical quadtree structures with deeper coding depths. In our observations in HEVC codec, significantly different characteristics of transform residues are shown according to the CU depth levels. Motivated the observations, we...

Due to the higher requirements associated with Ultra High Definition (UHD) resolutions in terms of memory and transmission bandwidth, the feasibility of UHD video communication applications is strongly dependent on the performance of video compression solutions. Even though the High Efficiency Video Coding (HEVC) standard allows significantly superior rate-distortion performances compared to pr...

—High Efficiency Video Coding (HEVC) exploits quad-tree structured Coding Unit (CU) to improve compression efficiency. It saves about 50% coding bits as compared with the former standard H.264/AVC high profile. However, the computational complexity is dramatically increased for more partition blocks and coding modes supported in HEVC. In this paper, a fast CU decision algorithm is proposed to ...

Video encoding for multimedia services over communication networks has significantly advanced in recent years with the development of the highly efficient and flexible H.264 SVC video coding standard.
