Radio and television cable network scientific development report is about to come out

The report generally considers that in the face of the new situation in the rapid development of new-generation information technologies such as cloud computing, big data, mobile Internet and smart terminals, as well as the new pattern of triple-play convergence and industry transformation and development, the radio and television cable network industry has made scientific and technological progress and institutional reforms. As a driving force, the next-generation radio and television network (NGB) innovation strategy leads the practice and development, and has made a series of new explorations in promoting the integration and development of traditional media and new media, expanding information and full-service services, and achieving bidirectionalization of radio and television cable networks. Broadbandization has achieved new breakthroughs in further enhancing service aggregation capabilities, high-quality audio and video transmission capabilities, full-service operational capabilities, and intelligent service levels.

The report pointed out that China quickly started the application of AVS+ in the field of broadcasting and television, formulated the technical specifications for NGB video on demand systems (GY/T 258-2012), the metadata specification for NGB video on demand systems (GY/T259-2012), and terminal middleware. And the Downloadable Conditional Access (DCAS) specification, the Smart TV Terminal Operating System (TVOS) standard, and the three wireline broadband access network standards, initiated the work of the Wired Broadband Access Network standard 2.0, and is developing a CDN standard with relevant autonomous knowledge. The property rights technical standards system has been initially established.

In terms of triple play, the pace of application and promotion of new technologies has been further accelerated. Building an open and converged service cloud platform has become a hot spot; HDTVs, ultra-high definition televisions and 3D TVs are being vigorously promoted; IP-based communication technologies have enabled multi-screen coverage and can provide "TV everywhere" video services; using advanced optical communications Technology accelerates the pace of building intelligent pipelines; Accelerates the construction of two-way networks and expands broadband services; User terminals develop in the direction of intelligence, convergence, and diversification; IPV4/IPV6 coexistence and transition technology applications start; and the completion of wireless 700M band 4G transmission pilot .

The report also compares the domestic and international applied research from two aspects of the technical standards system and the application of new technologies, and analyzes the development of related industries such as radio and television cable networks, Internet radio and television, OTT TV, wireless audio and video services, and IPTV. The industry revolution has accelerated, and traditional radio and television cable networks are facing unprecedented challenges and impacts. With the intensified industrial convergence, the traditional radio and television cable network can no longer be just a geographically isolated physical network. It should gradually transform itself into an integrated service operator. A variety of video transmission technologies have developed rapidly, and the era of big video is coming. The global is facing the same difficulties in structural adjustment and comprehensive transformation brought about by digitalization, networking, and intelligence.

Based on an analysis of the advantages, opportunities, disadvantages, and challenges of the follow-up development of domestic radio and television cable networks, the report proposes three development proposals: 1. The radio and television cable network should be re-understood. Radio and television cable network from the basic properties, not only the radio and television technology network; from the perspective of business carrying, not limited to radio and television transmission; from the network coverage point of view, not just a fixed ground network; from the perspective of industrial ecology, not just a transmission link. 2. The radio and television cable network should be repositioned. The radio and television cable network in the new era is the main position and main channel of mainstream ideological communication, an important information network infrastructure in the country and the region, and the main carrier and main operator of digital homes and smart city informationization. "And the small three networks" new integration network. 3. New breakthroughs in fusion development should be achieved. We should make the production and broadcasting of content from a single closed, specialized, inefficient and energy-efficient way, to an open, integrated, flexible, efficient, and green, intelligent and personalized way; make the distribution of transmission from the network isolated, single means, low transmission The effective way is to change the direction of network interconnection, interoperability, intelligent coordination, multiple means, intelligent perception, and efficient transmission; to make receiving terminals and services from a single form, independent reception, common functions, to multi-modal, multi-screen collaborative, intelligent Way to change.

It is reported that the development report of Radio and TV cable network discipline was written and completed by the expert committee of the China Cable Electronics Association's CATV Sub-Committee after extensive investigations over several months, condensing the wisdom and efforts of the experts. The Committee of Experts will hold the “23rd China Digital Broadcasting, Television and Network Development Annual Conference (CCNS 2015)” and “The 14th National Conference on Internet and Audio and Video Broadcasting Development (NWC 2015)” held in Yangzhou in April 2015. Publicly publish the report for the first time.
