| Abstract | Testing Digital TV applications is not a simple task. DTV applications either need to be transmitted by a TV broadcaster or someone with an equipment capable of generating a DTV signal with the application embedded. Alternatively, an interactive TV application developer may use a virtual execution environment, like a virtual set-top box installed in a computer, which implements the digital TV middleware standard. In both cases, the application usually does not reach a large number of final users, and developers may not be motivated to continue working with digital TV interactive content. On the other hand, HTML5 support for multimedia content will certainly attract multimedia authors to web development. Considering this scenario, this work proposes an alternative way of presenting a digital TV application developed in NCL for the Ginga declarative middleware, translating it into HTML5 web pages, so it can be presented using a common web browser. The translation tool is called NCL4WEB. Like HTML, NCL is XML-based, so NCL4WEB is based on XSLT stylesheets. It transforms NCL elements into HTML5 elements and a set of JavaScript functions that implement synchronization relationships among media objects, including user interaction. Using NCL4WEB, NCL developers are able to publish their interactive TV applications on the web. It is transparent for final users to access HTML5 or NCL content using a web browser. |

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.
