互联网和通信技术的发展极大地推动了广电技术的突破。文章以Web of Science核心合集收录的近10年广电技术文献和Derwent数据库中的专利数据为基础,分别对广电技术研究的年度发表的文献数量、国家/地区、主要研究机构、研究主要领域分布、主要研究热点、专利数量、专利申请机构等内容进行分析。结果表明,相关研究的文献和专利数量逐年在增长;广电技术研究涉及多个技术领域;美国在该研究领域处于世界领先地位;我国在广电技术“产学研”协作方面应该加强。
The development of Internet and communication technology has greatly promoted the breakthrough of radio and television technology. Based on the nearly ten years of radio and television technical documents collected in the core collection of Web of Science and the patent data in the Derwent database, the paper respectively distributes the annual number of published articles on radio and television technology research, countries / regions, major research institutions, major research areas, Major research hot spots, the number of patents, patent application agencies and other content analysis. The results show that the number of related research literature and patents is increasing year by year. The research on radio and television technology involves a number of technical fields. The United States is the world leader in this field of study. China should strengthen its cooperation in radio and television technology.
