Preface

For a long time, the helplessness felt by the engineering and technical personnel in the front line of broadcasting technology and the ones who have just graduated from schools can be easily perceived. Facing the complex broadcasting system, they try to integrate into the broadcasting industry as soon as possible but in most cases, they don’t know how to achieve it. Without an effective, comprehensive and systematic guide book, they can only integrate into the industry by relying on their knowledge learned before and groping and re-studying by themselves. This procedure always takes a long time, ranging from three years to ten years, or even longer. Besides, the engineering personnel who engage in the specific part of broadcasting system always feel the difficulty of grasping the relative knowledge from the system level because of the limitation of their business. This also cause the waste of time, manpower cost and national resources.

   Entering the 21 centuries, China will speed up the implementation of the “smart radio and television” strategy, whose main purpose is to create the smart media and new smart kinetic energy and strengthen the ability of sustainable development. At present, China is striving to promote integration and innovation in ideas, contents, genres, forms, methods, means, formats, systems and mechanisms in order to form new thinking concepts, new technical means, and new systems and mechanisms that meet the requirements of the new development concept.

   China also requires the radio, television and other media to make great efforts to strengthen the construction of their international communication capacity. With rich information, distinct Chinese perspective and broad world vision, the media will publicize and explain China’s roads, China’s theories and China’s institutions to the international community and show the good image of China as a builder of world peace, a contributor to global development and a defender of international order. Besides, the radio and television are required to give a good narration of Chinese story and a wide spread of Chinese voice, work hard on “the Belt and Road Initiatives”, consolidate the mainstream of Africa, open up Latin American market, stabilize the neighboring countries, enhance the influence on Europe and America and make further efforts to serve the national strategy.

前 言

长期以来，深感从事广播技术第一线的工程技术人员以及刚走出校门的技术人员，在从事广播系统工程时，常常对纷繁复杂的广播系统感到无从下手，虽然他们都想尽快融入广播事业中，但总觉得缺乏一种有效的、较全面的、系统的指导书，全靠自已结合原先学到的知识，再摸索和再学习总结，这个周期往往很长，少则三五年，多则十年八年，甚至还更久。还有就是由于每个从事具体局部系统工作的工程人员，受所从事的业务面的限制，也往往很难从系统的层面来较全面把握这些知识，从而造成时间和人力成本的浪费，造成国家资源的浪费。
       进入 21 世纪， 国家将加快实施“智慧广电” 战略， 其主旨在于打造智慧融媒体，创造智慧新动能，增强持续发展能力。目前，国家正着力推动融合创新，创新理念、内容、体裁、形式、方法、手段、业态、体制、机制，形成符合新发展理念要求的新思维观念、新技术手段、新体制机制。
       国家还要求广播电视等媒体下大力气加强国际传播能力建设，以丰富的信息资讯、鲜明的中国视角、广阔的世界眼光，向国际社会宣传阐释中国道路、中国理论、中国制度，展示中国作为世界和平的建设者、全球发展的贡献者、国际秩序的维护者的良好形象；要求广播电视讲好中国故事、 传播好中国声音，深耕“一带一路”、巩固非洲主流、开拓拉美市场、稳固周边友邻、提升对欧美的影响，进一步服务好国家战略。
