Abstract | An efficient lossless coding technique is very important for storage and transmission applications of error sensitive information such as medical, seismic and digital artistic data. In this study, the authors proposed an H.264-based advance video coding (H.264/AVC)-based hierarchical lossless coding method, where the input video will be firstly encoded by H.264/AVC coder with a quantisation parameter (QP) selector in the base layer and the coded error is encoded by a QP-adaptive Rice coder in the enhancement layer. To reduce encoding time, the QP selector can be simplified to select the nearly optimal QP. Simulation results show that the proposed hierarchical lossless coding architecture achieves better compression ratio than the traditional H.264/AVC-based lossless coding systems. Since the proposed system could provide both lossy and lossless coding services at the same time, the proposed lossless video coding system has advantages of efficiency and flexibility for practical applications. Experimental results show that the proposed coding system can provide less coding bits and reduce coding complexity compare with H.264-differential pulse code modulation. |

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.
