| Abstract | This paper presents a new algorithm of scalable video coding base on frequency spectrum. Data partition in MPEG-2 is an early scalable video coding base on spectrum, but it is rough in scalable granularity and low in practicability, while the algorithm proposed in this paper can achieve finer granularity of scalability (9 levels). The algorithm base on frequency spectrum has flexible scalability, low complexity and high efficiency, but it brings a problem of error accumulation through prediction. Because if it only transmits part of DCT coefficients, it makes reference frames of encoder differ from reference frames of decoder which results in error accumulation. This problem is solved by setting references frames in transform region in this paper. AVS-P2 is a new generation of video coding standard with independent intellectual property in China, and it has become a national standard. In this paper, the algorithm of scalable video coding is combined with AVS-P2 and is realized under the framework of AVS-P2. Finally, the algorithm was realized based on the software codec model version rm52j of AVS-P2 and testified the scalable video coding model through several tests. |

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.
