| Abstract | With the rapid development of information technology, television has started the development evolution which is from the first generation digital television (DVB-C, DVB-S, DVB-T, ATSC, ISDB-T, DTMB) to the second generation digital television (DVB-C2, DVB-S2, DVB-T2, ATSC 3.0). Interiorly, to cooperate the information industry development strategic target of triple play in China, SARFT has launched the strategic plan of Next Generation Broadcasting (NGB), and set “suitable to Chinese conditions, triple play, combination of wire and wireless, the whole process and network” as strategic target of next generation broadcasting in China. NGB-W is the wireless part of Chinese Next Generation Broadcasting, it is a three-dimensional complete coverage intelligent fusion media network which includes terrestrial mobile, terrestrial fixed and satellite network. NGB-W is and advanced technology scheme which is suitable to Chinese conditions, and satisfies the business and technology requirements of NGB-W system. This scheme takes OFDM and LDPC as the core, meanwhile, it absorbs BICM, space diversity and space multiplexing, carrier aggregation and other the latest technological achievements and systematic design idea in existing wireless communication technique. It not only is relatively improved than the first generation technology on the transmission efficiency, but also has good flexibility and compatibility, and it can effectively satisfy all media services demand of next generation broadcasting television system. This paper will give a brief introduction to the new designed NGB-W broadcasting channel technology scheme, which includes network architecture, technology architecture, system parameters and scheme performance. In section 1, we will briefly introduce the corresponding background of NGB-W. In section 2, we will introduce the network architecture and link structure of NGB-W broadcasting. In section 3, we will emphatically introduce the technology architecture and system parameters of NGB-W broadcasting channel technology scheme. In section 4, we will compare the NGB-W technology with other existing technologies in the aspects of the key technologies and performance index. In the last section, we will give a brief conclusion. |

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.
