Abstract | Robust video coding is creating coded video data which provides received and decoded video of application-appropriate quality when transmitted over an imperfect channel. Video contains an enormous amount of redundancy, both from signal processing and psychological perspectives, which effective compression attempts to remove. However, ideal source coding leaves a coded stream which is extremely vulnerable to errors, and therefore compression and transmission provisions that avoid catastrophic failure caused by lost, delayed, or errant data are imperative. Robustness in video coding is obtained through source coding, channel coding, and error concealment following decoding. This paper first discusses issues specific to video in providing robustness and then poses the problem with two extremes of providing robustness and an example. Common strategies employed in robust video coding are then briefly described, and the specific application of these strategies in session papers are presented. The paper concludes with a discussion of future directions in robust video coding. |

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.
