“…Luma ZB contributes a reasonable amount as shown in Table 1. These values are obtained from 20 frames of two HD videos respectively, under the random access condition tested by HM10.0 with some fast search options, which are detailed in Reference [5]. Subtle difference between the reference video frame and its corresponding compressed version could not be observed by human eyes according to human inherent visual redundancy.…”

“…Four different concepts, Coding Tree Unit (CTU), Coding Unit (CU), Prediction Unit (PU) and Transform Unit (TU) are introduced in HEVC. This variable-size, adaptive approach is particularly suited to larger resolutions and plays a major role in the substantial performance gains exhibited by HEVC relative to previous video coding standards [4] [5]. Meanwhile, it brings high computational complexity because the optimal partitioning is estimated in a rate-distortion sense at the encoder sides by testing all kinds of partitions.…”

Abstract-The new introduced concept, transform tree or residual quadtree (RQT) in HEVC standard, brings high coding performance along with high computational complexity because the optimal TU partition is estimated in a ratedistortion sense at the encoder sides by testing all kinds of partitions. This paper focus on early TU split termination in terms of the tradeoff between computation and coding quality. An early TU split termination scheme based on quasi-zeroblock (QZB) is proposed, which is defined by two aspects about the quantized transform coefficients; the sum of all absolute coefficients and the number of nonzero coefficients. Besides, the selective probability of every TU depth is calculated and analyzed. Experimental results show that the proposed method (HM-QZB) could achieve 22.8% reduction in encoding time and 50.59% reduction in TU processing time compared to the HEVC test model HM10.0 encoder with about 0.04dB BD-PSNR loss in coding performance.

“…The popularity of High Definition (HD) and Ultra-High Definition (UHD) video content and the requirements for the bandwidth efficiency have motivated the introduction of novel video compression standards such as High Efficiency Video Coding (HEVC) [2]. However, the significant increase in the complexity of HEVC [3] has become a non-trivial bottleneck for the video playback in resource constrained handheld consumer electronic (CE) devices such as smartphones, tablets etc. In this context, decoder energy-aware video encoding is becoming crucially important to address the rising video demands and the constraints of the CE devices.…”

“…They consume more than 90% of encoding time [5]. Although, HEVC provides a simple inter prediction process, the overhead involved is larger compared to H.264/MPEG-4, which consequently increases the complexity of HEVC encoder [6]. Typically as in H.264/MPEG-4 AVC, for every prediction block (PB) in HEVC, block matching algorithm (BMA) finds the best matching block within a certain search window.…”

Abstract-The high computational cost of the motion estimation module in the new HEVC standard raises the need for efficient hardware architectures that can meet the real-time processing constraint. In addition, targeting HD and UHD resolutions increases the motion estimation processing cost beyond the capabilities of the currently existing architectures. This paper presents a highly parallel sum of absolute difference (SAD) architecture for motion estimation in HEVC encoder. The proposed architecture has 64 PUs operating in parallel to calculate the SAD values of the prediction blocks. It processes block sizes from 4x4 up to 64x64. The proposed architecture has been prototyped, simulated and synthesized on Xilinx Virtix-7 XC7VX550T FPGA. At 458 MHz clock frequency, the proposed architecture processes 30 2K resolution fps with ±20 pixels search range. The prototyped architecture utilizes 7% of the LUTs and 5% of the slice registers in Xilinx Virtex-7 XC7VX550T FPGA.
