| Abstract | The research on distributed video coding (DVC) has been increasingly popular in recent times due to its promising features. DVC primarily has a modified complexity balance between the encoder and decoder, in contrast to conventional video codecs. In video communications over wireless channels, the noise and multipath fading effects have a significant effect on the perceptual video quality experienced at the decoder. However, it is noted that in all the research literature on DVC, an error-free ideal communication channel is assumed between the encoder and decoder. In this paper, we take into account the effects of noise and fading in a wireless channel on the performance of a DVC codec with necessary modifications to the decoding algorithm while proposing a higher order (4x4) MIMO based diversity scheme to take advantage of the multipath propagation effects to improve the performance. Simulation results show that the proposed DVC system outperform the state of the art H.264 video codec at low SNR levels. |

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.
