| Abstract | In this paper, a novel quadratic ρ-domain frame layer rate control algorithm is proposed for Low Delay (LD) configuration in High Efficiency Video Coding (HEVC). Firstly, we propose a quadratic ρ-domain rate quantization (R-Q) model to establish the relationship between bit rate and quantization parameter. Subsequently, inspired by the specialized QP determination and reference picture set (RPS) mechanism, we design a RPS based hierarchical partition structure for rate control. Based on the hierarchical partition, an efficient hierarchical bit allocation scheme is provided. Finally, the quantization parameter (QP) is calculated via the proposed R-Q model after the bit allocation to meet the target bits. Experimental results demonstrate the proposed algorithm can significantly improve the R-D performance compared to the state-of-the-art rate control scheme for HEVC. Moreover, our proposed algorithm also provides smaller mismatch between the target bit rate and the actual bit rate. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
