For extension of High Efficient Video Coding (HEVC), a high quality experience is offered by using three-dimensional (3-D) video. Also, the primary usage scenario for multiview video is to support 3-D video applications, where 3-D depth perception of a visual scene is provided by a 3-D display system. The efficient representation and compression of stereo and multiview video is a central compon...

This paper discusses robust coding of visual content for a distributed multimedia system. The system encodes independently two correlated video signals and reconstructs them jointly at a central decoder. The video signals are captured from a dynamic scene, where each signal is robustly coded by amotion-compensatedHaar wavelet. The efficiency of the decoder is improved by a disparity analysis of...

Context-Based Adaptive Binary Arithmetic Coding (CABAC) is a method of entropy coding first introduced in H.264/AVC and now used in the latest High Efficiency Video Coding (HEVC) standard. While it provides high coding efficiency, the data dependencies in H.264/AVC CABAC make it challenging to parallelize and thus limit its throughput. Accordingly, during the standardization of entropy coding f...

High Efficiency Video Coding (HEVC) is the state-of-art-video coding standard which significantly improved the coding efficiency of a coded video signal with its preceding video coding standards. This paper presents technical aspects of HEVC thought objective and subjective performance analysis of different versions of HM software test models in different configurations in Main profile. We comp...

This paper (for Part I, see [8]) proposes a new context-based adaptive variable length coding scheme (CBAVLC) for video DCT blocks, aiming to maximize the achievable coding efficiency under acceptable complexity in practical video coding. CBAVLC is designed by following the theoretically optimal approach described in Part I. The proposed context modeling in CBAVLC is domain knowledge drove, whi...

in video coding, intra coding plays an important role in both coding efficiency and error resilience, and current intra coding methods still have great potential to be further investigated. In this paper, a high performance intra coding method based on video epitomic analysis is proposed. Epitomic priors suitable for coding are extracted through video epitomic analysis, and are used to generate...

Streaming Video Profile is the subject of an Amendment of MPEG-4, and is developed in response to the growing need on a video-coding standard for streaming video over the Internet. It provides the capability to distribute single-layered frame-based video over a wide range of bit rates with high coding efficiency. It also provides fine granularity scalability (FGS), and its combination with temp...

The high efficiency video coding (HEVC) standard has significantly improved compression performance for many applications, including remote desktop and desktop sharing. Screen content video coding is widely used in applications with a high demand for real-time performance. HEVC usually introduces great computational complexity, which makes fast algorithms necessary to offset the limited computi...

Entropy coding is one of the most important techniques in video codec. Two main criteria to assess an entropy coder are coding efficiency and friendly realization characteristic. In the recent development of the H.264/AVC standard, a sophisticated entropy coder, named Context-based Adaptive Variable Length Coding (CAVLC), has been invented, which supplies higher coding efficiency than other VLC...
