Abstract | Recently HTTP adaptive streaming (HAS) has been leading the trend in the delivery of video content over Internet. The scope of this technology describes that a video is segmented into small intervals and encoded in different qualities for adapting the variance of network bandwidth. This method allows the client adjusting the quality of the requested stream dynamically. To the best of our knowledge, most heuristic algorithms proposed for HAS run a risk of freezing in video playback and thus induce a poor Quality of Experience (QoE). Therefore, how to maintain a good user experience becomes a more challenging task for the service provider. In this paper, we propose a optimal scheduling of QoE-aware HAS method which achieves the following QoE requirements. (1) Avoiding video streaming freezing (i.e. the client buffer underflow). (2) Minimizing the initial delay before the video streaming starts playing. Testing by the video Aladdin, experimental results show that our method can find the best QoE service for HAS under various QoE requirements and resource constraints. |

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.
