| Abstract | This paper addresses the problem of wireless delivery of a captured scene from multiple cameras, which do not communicate among one other, to a joint decoder. Correlation among different camera views calls for distributed source coding for efficient compression. The fact that the cameras may be placed within a short communication range of each other results in a high level of interference, multipath fading, and noise effects, during transmission. We develop a new two-camera system, where one camera employs H.264 SVC, whereas the other, low-complexity camera codec exploits statistical dependencies between closely-located cameras' views to jointly perform compression and spreading using Complete Complementary (CC) sequences for protection against interference. This paper proposes a very low complexity scalable coding scheme using fixed integer Discrete Cosine Transform (DCT) and fixed quantizer matrices instead of the 2D DCT. The proposed system is targeted at wireless multi-view video streaming applications, in which the data acquired form different viewing cameras are highly correlated spatially and temporally. Our results indicate that our proposed system is competitive with H264 SVC coded streams. |

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.
