High efficiency video coding (HEVC) is the next generation video compression standard. In-loop filter is an important component of HEVC which is composed of two parts, deblocking filter (DBF) and sample adaptive offset (SAO). In this article, we propose a high performance in-loop filter architecture for HEVC which integrate both deblocking filter and SAO. To achieve it, several ideas are adopte...

Significant progress has been made recently towards the next generation video coding standard by the Joint Collaborative Team on Video Coding (JCT-VC) of ISO/IEC Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG). The test model, known as High Efficiency Video Coding (HEVC), aims to achieve 50% coding gain over the current MPEG4/H.264 AVC standard. Recently reported...

The latest video coding standard High Efficiency Video Coding (HEVC) [1] provides 50% improvement in coding efficiency compared to H.264/AVC, to meet the rising demand for video streaming, better video quality and higher resolutions. The coding gain is achieved using more complex tools such as larger and variable-size coding units (CU) in a hierarchical structure, larger transforms and longer i...

The coding efficiency of three generations of video coding standards is compared by means of PSNR and subjective testing in interactive video applications, such as video chat, video conferencing and telepresence systems. An unified approach is applied to the analysis of designs of MPEG-H HEVC/H.265, MPEG-4 AVC/H.264, and H.263 reference software implementation. The results of performance tests ...

In this paper, we propose a complexity reduction method of sample adaptive offset (SAO), which is an in-loop filter in high-efficiency video coding (HEVC). In the conventional SAO, an offset value is calculated for each coding tree block (CTB) to minimize the error between the original and reconstructed images. In order to determine the optimal offset value, all offset candidates are examined a...

High Efficiency Video Coding (HEVC) is an advanced video coding technique, which is designed to double the Data compression ratio compared to the other video standard with the same level of video quality. The HEVC video coding layer uses the same hybrid approach used in all modern video standards used in earlier H.264. To achieve the high compression ration HEVC supports the recursive quad-tree...

Advances in multimedia devices, video compression efficiency and increased availability of network bandwidth have increased the proliferation of multimedia applications. However, the proliferation of these applications has also increased the need to maximize available network resources and also meet end users’ Quality of Experience (QoE) and expectations. We present results for end-to-end video...

The content of this White Paper has originally been published in Signal Processing: Image Communication journal. New generations of video compression algorithms, such as those included in the under development High Efficiency Video Coding (HEVC) standard, provide substantially higher compression compared to their ancestors. The gain is achieved by improved prediction of pixels, both within a fr...

According to recent forecast, mobile video will generate over 69 percent of global mobile data traffic by 2018. Due to this the liability on video service providers to match the video quality expectations of the end user has increased. The goal of video coding is to ensure good video quality within the provision of transmission and storage. Bit rates, distortion and complexity are factors that ...

This paper presents a pixel-by-pixel spatial prediction method for lossless intra coding within High Efficiency Video Coding (HEVC). A well-known previous pixel-by-pixel spatial prediction method uses only two neighboring pixels for prediction, based on the angular projection idea borrowed from block-based intra prediction in lossy coding. This paper explores a method which uses three neighbori...
