| Abstract | This work studies the error resilience of pixel-domain distributed video coding in noisy wireless transmission environment. Turbo codes are used to implement the DVC coder and the AWGN model is assumed for the transmission channel. The goal is to find out whether symbol based coding or bit-plane based coding is more robust against channel noise. We compare the two in the context of joint source-channel coding to ensure a high error resilience. First, we propose a framework to estimate the end-to-end distortion for these two schemes. Next, we allocate the rate between source coding and channel coding, aiming at a minimum end-to-end distortion. Then, we simulate the two schemes, setting the same bit budget for them, and compare their error resilience. Experimental results show that symbol based coding outperforms bit-plane based coding by up to 0.7 dB in PSNR of the decoded video. |

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.
