The Open-Source Turing Codec: Towards Fast, Flexible and Parallel Hevc Encoding
THE OPEN-SOURCE TURING CODEC: TOWARDS FAST, FLEXIBLE AND PARALLEL HEVC ENCODING S. G. Blasi1, M. Naccari1, R. Weerakkody1, J. Funnell2 and M. Mrak1 1BBC, Research and Development Department, UK 2Parabola Research, UK ABSTRACT The Turing codec is an open-source software codec compliant with the HEVC standard and specifically designed for speed, flexibility, parallelisation and high coding efficiency. The Turing codec was designed starting from a completely novel backbone to comply with the Main and Main10 profiles of HEVC, and has many desirable features for practical codecs such as very low memory consumption, advanced parallelisation schemes and fast encoding algorithms. This paper presents a technical description of the Turing codec as well as a comparison of its performance with other similar encoders. The codec is capable of cutting the encoding complexity by an average 87% with respect to the HEVC reference implementation for an average coding penalty of 11% higher rates in compression efficiency at the same peak-signal-noise-ratio level. INTRODUCTION The ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) combined their expertise to form the Joint Collaborative Team on Video Coding (JCT-VC), and finalised the first version of the H.265/High Efficiency Video Coding (HEVC) standard (1) in January 2013. HEVC provides the same perceived video quality as its predecessor H.264/Advanced Video Coding (AVC) at considerably lower bitrates (the MPEG final verification tests report average bitrate reductions of up to 60% (2) when coding Ultra High Definition, UHD, content). HEVC specifies larger block sizes for prediction and transform, an additional in-loop filter, and new coding modes for intra- and inter-prediction. -
Design and Analysis of Video Compression Technique Using Hevc Intra-Frame Coding K

Sripal Reddy*1, Boppidi Srikanth2 & C. Loknath Reddy3 *1,2&3Vardhaman College of Engineering DOI: 10.5281/zenodo.817839 ABSTRACT High Efficiency Video Coding (HEVC) is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards in the range of 50% bit-rate reduction for equal perceptual video quality. Intra-frame coding is essential in both still image and video coding. In the block-based coding scheme, the spatial redundancy can be removed by utilizing the correlation between the current pixel and its neighboring reconstructed pixels from the differential pulse code modulation (DPCM) in the early video coding standard H.261 to the angular intra prediction in the latest H.265/HEVC [1], different intra prediction schemes are employed. Almost without exception, linear filters are used in these prediction schemes. This paper provides an overview of the Intra-frame coding techniques of the HEVC standard. KEYWORDS: High Efficiency Video Coding (HEVC), Intra- frame coding, angular intra prediction. I. INTRODUCTION Along with the development of multimedia and hardware technologies, the demand for high-resolution video services with better quality has been increasing. These days, the demand for ultrahigh definition (UHD) video services is emerging, and its resolution is higher than that of full high definition (FHD), by a factor of 4 or more. -

Parallel Deblocking Filter Based on Modified Order of Accessing the Coding Tree Units for HEVC on Multicore Processor
KSII TRANSACTIONS ON INTERNET AND INFORMATION SYSTEMS VOL. 11, NO. 3, Mar. 2017 1684 Copyright ⓒ2017 KSII Parallel Deblocking Filter Based on Modified Order of Accessing the Coding Tree Units for HEVC on Multicore Processor Haiwei Lei1, Wenyi Liu1 and Anhong Wang2 1 Key Laboratory of Instrumentation Science & Dynamic Measurement, Ministry of Education, North University of China Taiyuan, 030051- China [e-mail: [email protected]; [email protected]] 2 School of Electronic Information Engineering, Taiyuan University of Science and Technology Taiyuan, 030024 - China [e-mail: [email protected]] *Corresponding author: Wenyi Liu; Anhong Wang Received April 11, 2016; revised October 18, 2016; revised December 12, 2016; accepted January 15, 2017; published March 31, 2017 Abstract The deblocking filter (DF) reduces blocking artifacts in encoded video sequences, and thereby significantly improves the subjective and objective quality of videos. Statistics show that the DF accounts for 5–18% of the total decoding time in high-efficiency video coding. Therefore, speeding up the DF will improve codec performance, especially for the decoder. In view of the rapid development of multicore technology, we propose a parallel DF scheme based on a modified order of accessing the coding tree units (CTUs) by analyzing the data dependencies between adjacent CTUs. This enables the DF to run in parallel, providing accelerated performance and more flexibility in the degree of parallelism, as well as finer parallel granularity. We additionally solve the problems of variable privatization and thread synchronization in the parallelization of the DF. Finally, the DF module is parallelized based on the HM16.1 reference software using OpenMP technology.
