Abstract | In general, low and very-low bitrate video communication systems cannot achieve the full frame rate (25 Hz for PAL or 30 Hz for NSTC), which brings temporal distortion. The influence of reduced frame rate on subjective quality evaluation is a very important topic for both perceptual quality metrics and communication system optimization. In this paper, we present our work on the numerical modeling of the influence. The work includes two parts: first we measured the detectability and annoyance of periodic frame dropping's effect on perceptual visual quality evaluation under different content and frame size conditions. Then, a simple and effective feature is proposed to represent the content of video in temporal quality evaluation. The high Pearson and Spearman correlation results between the MOS and proposed model, as well as the results of other two error metrics, confirm the success of the selected temporal content-quality feature. |

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.
