| Abstract | With the popularization and ripeness of DTV (Digital television) and IPTV (Internet Protocol television), the STB (Set-Top Box) devices are playing more and more important roles in improving the interactive TV applications. Through STB devices, millions of users can publish/subscribe their interested events when they are participating in different applications. Furthermore, it is likely that a very large number of events would be published simultaneously and processing these events under critical timing constrains is often required by lots of applications. How to subscribe and process this large amount of events in real time is rather a challenge to both academia and industry. The combination of Cloud Computing and DDS (Data Distribution Service) middleware brings us a promising way to address this issue. Cloud computing can not only provide sufficient computing capacity but also reduce the processing cost in a great lot. Besides, DDS middleware supports real-time publish/subscribe communication model and is often used in military scenario. In this paper, in order to process such a large scale and high concurrency events efficiently and real-time, we propose a cloud-based architecture for STB event processing. Besides, we discuss the implementation details of reliability and load balancing. To demonstrate the effectiveness of our approach some experiments on the prototype are evaluated. |

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.
