| Abstract | Transmission of compressed video over packet lossy networks suffers from the problem of error propagation which deteriorate the reconstruction quality of a number of successive frames. For conversational video communication, this problem becomes more severe due to the localization and predominance of the attention-attracted areas, where the motion compensated prediction errors have more energy compared to that of the relatively invariable background. In this paper, we propose an error resilient coding scheme for conversational video communication. The proposed scheme combines the region-of-interest (ROI) segmentation and the long-term reference (LTR) frame coding. The scheme can be easily integrated into the H.264/AVC encoder, and efficiently improve the video quality of the ROI areas. Simulation results verify the robustness and coding efficiency as well as improved subjective visual quality. |

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.
