| Abstract | The main challenge for provisioning of Mobile TV services is to overcome long burst errors as are often found in mobile reception conditions. Long time interleaving can be implemented by means of Application Layer FEC (AL-FEC) to increase the time diversity of the signal and thereby its robustness against burst errors. The main obstacle of long time interleaving for streaming services is the increase in service tune-in time, which significantly decreases the Quality of Experience (QoE) of end users. That is why today's Mobile TV systems are provisioned in a way to minimize the time interleaving length to provide an acceptable tune-in time, though the service robustness would significantly benefit from a longer interleaving length. This paper presents a new way of service provisioning that marries fast zapping and long time interleaving by combining Layer-Aware FEC and layered media codecs with unequal time interleaving and an appropriate transmission scheduling. The effect of the proposed scheme on the QoE as well as the service tune-in time is analyzed. Simulation results within a Gilbert-Elliot channel report the benefit of the proposed scheme, which for the first time enables broadcast services with fast tune-in and at the same time long time interleaving. |

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.
