| Abstract | Real time transmission of compressed video data over power line channels is a challenging task because of the severe characteristics of the power line transmission medium. Several techniques have been investigated recently to make a compressed video bitstream robust to the channel distortions. In this paper, we consider the benefit of using hierarchical transmission for error resilience. We propose an original video transmission scheme based on layered video coding combined with unequal error protection. Here, unequal error protection is achieved using a hierarchical multi-carrier modulation scheme based on hierarchical quadrature amplitude modulation. In particular, we propose a hierarchical bit and power allocation algorithm specific to hierarchical MCM. Some simulation results are presented to show the interest of applying unequal error protection by hierarchical coding of layered video bitstreams. |

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.
