Fast Coding Algorithm for High Efficient Video Coding (HEVC)
2012The JCT-VC is developing the next-generation video coding standard which is called a high efficiency video coding (HEVC). In the HEVC, there are three unit in block structure: coding unit (CU), prediction unit (PU), and transform unit (TU). The CU is the basic unit of region splitting like macroblock.

Core Transform Design in the High Efficiency Video Coding (HEVC) Standard
IEEE Journal of Selected Topics in Signal Processing, 2013This paper describes the core transforms specified for the high efficiency video coding (HEVC) standard. Core transform matrices of various sizes from 4 × 4 to 32 × 32 were designed as finite precision approximations to the discrete cosine transform (DCT).

Multi-loop scalable video codec based on high efficiency video coding (HEVC)
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013A multi-loop scalable video coder for high efficiency video coding (HEVC) is proposed in this paper. A coding unit (CU)-level inter-layer sample prediction tool is proposed to exploit redundancy between enhancement-layer and up-sampled base-layer pictures.

On fast coding tree block and mode decision for high-Efficiency Video Coding (HEVC)
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012In the current HEVC test model (HM), a quad-tree based coding tree block (CTB) representation is used to signal mode, partition, prediction and residual information. The large number of combinations of quad-tree partitions and modes to be tested during rate-distortion optimization (RDO) results in a high encoding complexity.

Recent developments in standardization of high efficiency video coding (HEVC)
SPIE Proceedings, 2010This paper reports on recent developments in video coding standardization, particularly focusing on the Call for Proposals (CfP) on video coding technology made jointly in January 2010 by ITU-T VCEG and ISO/IEC MPEG and the April 2010 responses to that Call.

High-Efficiency Video Coding (HEVC): The Next-Generation Compression Technology
SMPTE Motion Imaging Journal, 2011High-Efficiency Video Coding (HEVC) is in development and aims to revolutionize the compression world with a potential 50% bitrate saving over Advanced Video Coding (AVC, or H.264/MPEG-4 AVC). Is history repeating itself? There was a 10-year gap between the standardization of MPEG-2 Video and the standardization of AVC, with AVC eventually maturing to ...

A highly-parallel approach on motion estimation for high efficiency video coding (HEVC)
2014 IEEE International Conference on Consumer Electronics (ICCE), 2014The new High Efficiency Video Coding (HEVC) standard will most likely be used in many applications in the near future. However, the encoding process is extremely complex and hence very time consuming. We propose a hybrid encoding architecture, which uses a Graphics Processing Unit (GPU) to perform uni-predictive Motion Estimation (ME) in a highly ...

High efficiency video coding (HEVC) motion estimation parallel algorithms on GPU
2014 IEEE International Conference on Consumer Electronics - Taiwan, 2014Exhausted motion estimation in HEVC with variable block sizes is the bottleneck for real time encoding. Previous works show that CTU-based parallel processing will induce much coding efficiency loss. In this paper, focusing on the parallel processing in one CTU, efficient parallel algorithms are presented to accelerate integer motion estimation (IME ...
