| Abstract | Reliable delivery of 3D video contents to a wide set of users is expected to be the next big revolution in multimedia applications provided that it is possible to grant a certain level of Quality-of-Experience (QoE) to the end user. During the last years, several cross-layer solutions have proved to be extremely effective in tuning the transmission parameters at the different layers of the protocol stack and in maximizing the perceptual quality of the reconstructed 3D scene. Among these, Cognitive Source Coding (CSC) schemes (defined in analogy with Cognitive Radio systems) make possible to improve the quality of the 3D QoE at the receiver by adapting the source coding strategy according to the state of the transmission channel and to the characteristics of the coded signal. This knowledge also permits an optimization of the computational complexity required at the encoder. The paper presents a CSC architecture that analyzes the 3D scene, identifies the different elements, and chooses the most appropriate coding strategy via a classification of the features of each element based on Support Vector Machine theory. Experimental results show that the proposed approach permits improving the quality of the received 3D signal with respect to traditional cross-layer techniques and reducing the computational complexity of coding operation. |

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.
