| Abstract | The deployment of terrestrial/satellite networks, plays a crucial role for for risk and emergency management. In this context, efficient solutions for heterogeneous and mobile networks, including satellite portions that allows wide coverages, represents a key issue. In the mentioned scenario, transmitting video with portable devices (such as smartphone), over terrestrial/satellite networks, to a Remote Monitoring Host (RMH) may support emergency and rescue operations after crisis situations. Unfortunately heterogeneity often implies impairments such as packet losses, due to errors and congestion, which negatively affect the video quality. We present an application layer joint coding algorithm for video transmission, that adaptively applies video compression and channel coding at the application layer, on the basis of the overall network condition estimated in terms of maximum allowable throughput of the network and quality (packet cancellations or lossiness). A deep performance investigation, carried out with real implementation of the algorithm, compares the joint coding against fixed schemes and shows that the joint approach adapt the video transmission to terrestrial/satellite emergency networks so allowing a more efficient resource exploitation. |

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.
