Development of mixed screen content coding technology: SCC-HEVC extensions framework
نویسندگان
چکیده
The status of high efficiency video coding development is reviewed based on public available documents in HEVC version 4 standardization process. Here, the requirements and results of call for proposals on screen content coding (SCC) tools for HEVC are presented. The most significant additional coding tools are highlighted. To achieve high coding efficiency in SCC-HEVC, new coding tools that explore the correlation in screen content are developed: IBC block vector search, inter block search, palette mode, and adaptive colour transform. The performances of the coding tools are approved in verifications tests through cooperation phase of standardization process. Key-Words: image and video technologies, mixed content coding, standardization process

Overview of HEVC extensions on screen content coding
Technologies for coding non-camera-captured video contents have received great interests lately due to the rapid growth of application areas such as wireless display and screen sharing, etc. In response to the market demands, the ITU-T Video Coding Expert Group and ISO/IEC Motion Picture Expert Group have jointly launched a new standardization project, i.e. the HighEfficiency Video Coding (HEVC...
متن کاملOn Intra Prediction for Screen Content Video Coding
Screen content coding (SCC) is becoming increasingly important in various applications, such as desktop sharing, video conferencing, and remote education. When compared to natural cameracaptured content, screen content has different characteristics, in particular sharper edges. In this paper, we propose a novel intra prediction scheme for screen content video. In the proposed scheme, bilinear i...
متن کاملJND-Based Perceptual Video Coding for 4: 4: 4 Screen Content Data in HEVC
The JCT-VC standardized Screen Content Coding (SCC) extension in the HEVC HM RExt + SCM reference codec offers an impressive coding efficiency performance when compared with HM RExt alone; however, it is not significantly perceptually optimized. For instance, it does not include advanced HVS-based perceptual coding methods, such as Just Noticeable Distortion (JND)-based spatiotemporal masking s...
متن کاملAn HEVC-based Screen Content Coding Scheme
This document presents an efficient screen content coding scheme based on HEVC framework. The major techniques in the scheme includes hash-based large-scale block matching, dictionary mode, palette mode, adaptive color space coding, and several improvements to intra block copy mode. This scheme was submitted as our response to the joint Call for Proposals (CfP) for coding of screen content issu...
متن کاملFast CU Splitting in HEVC Intra Coding for Screen Content Coding
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...
