| Abstract | Summary form only given. Although a simple solution to multi-resolution video coding is the simulcast technique, in which each resolution of multi-resolution video is coded independently, a more efficient method is scalable coding. In scalable video coding, the lower resolution reproduction of the video is used in coding the higher resolution video. Temporal scalability is a tool intended for use in a range of applications, such as broadcasting of interlaced TV and progressive HDTV, for which migration to higher temporal resolution is necessary. Based on the simulation results with an MPEG-2 video encoder, it is observed that scalable coding with nonlinear interpolation achieves a 2-3 dB PSNR improvement over the simulcast coding at the same total bit-rate. However, for progressive input: interlace-to-interlace type temporal scalability, the scalable coding performance is lower than that of single layer progressive coding. This is expected as the coding performance decreases in interlaced coding due to the difficulty of motion estimation in interlaced sequences. |

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.
