| Abstract | When 3D video is transmitted over lossy channels, different strategies can be adopted at the different layers of the communication protocol stack to cope with such errors, in a cross-layer operation framework. At the receiver side, effective error concealment methods are necessary to overcome the quality loss due to erroneous packets. The existing concealment techniques for conventional 2D video can be individually applied for each component/view associated with 3D video. Novel error concealment methods which utilize inherent characteristics of 3D video are also emerging. This paper proposes a colour/texture initiated error concealment method for colour plus depth based 3D video. The error concealment process starts from the colour image sequence as accurate texture information is required to render good quality 2D/3D video with the DIBR (Depth Image-Based-Rendering) method. Since the depth map represents the basic structure of the corresponding colour image, the proposed method utilizes colour image concealment to conceal the errors in the associated depth map as well. This colour/texture image based temporal error concealment method is tested over a backward compatible Scalable Video Coding (SVC) architecture and a simulated packet loss network. The objective and subjective results/illustrations show that improved 2D/3D video quality can be achieved with the proposed method. |

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.
