| Abstract | Recent emerging development of three dimensional video (3DV) has been vigorously driving the Multiview Video Coding (MVC) standard developed by Joint Video Team as an amendment to H.264/AVC and the new 3DV standard developed by MPEG. It is expected that 3DV contents will soon be available to various media consumers. Because of the heterogeneous networks and terminal devices, a variety of end users shall not have (1) the 3DV decoder and view synthesize software installed on their devices, and (2) adequate network bandwidth for 3DV content delivery. 3DV transcoder is therefore necessary for users without 3DV decoder to enjoy 3DV services, as well as for service providers to better control virtual view quality of all 3DV customers. In this paper, we report the first 3DV transcoding scheme for virtual view, which is able to generate bitstream of one single view that can be decoded by H.264/AVC. The key idea of the proposed transcoding is to appropriately generate candidate motion and modes based on motion information from other views in the original bitstream making best use of inter-view correlation. These candidate motion and modes are then properly used to encode a virtual view with significantly reduced complexity for decoding by H.264/AVC. Simulation results show that, compared to the straightforward cascade algorithm, the proposed transcoding experiences minor performance loss with a significantly reduced computation cost. Such low complexity transcoding can be deployed at various media gateways to deliver 3DV content to non-3DV devices. |

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.
