| Abstract | Distributed video coding allows the compression of video frames in a distributed fashion leading to a rather simple computational encoding, but requiring a complex decoding. The main drawback however is the decoding complexity making some practical applications difficult. Nowadays, most distributed video coding schemes are based on efficient channel codes such as LDPC and Turbo codes. This is the main cause of the decoder's high complexity. This paper proposes a new distributed video coding scheme that can avoid the use of such codes. It is based on an adaptive representation of the source frames combined with a DC-guided scheme. This combination can reduce the data that need to be transmitted from the encoder to the decoder. This subsequently allows complex channel coding to be replaced by simple entropic coding methods, such as arithmetic source coding, with little performance degradation. Experimental results show that the proposed scheme can significantly improve the performance compared to conventional distributed video coding schemes, while enabling a much lower computational complex decoder. |

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.
