Since suspension of classes without stopping studying under the epidemic, it has become the top priority for teachers to achieve distance teaching relying on online video live broadcast and other means. Recently, teacher Xia Guanxiang of the School of Journalism and Communication combined his own advantages in radio and television engineering technology, using a variety of advanced hardware, software and technical means to build a low-cost, efficient, flexible and professional system of directing, shooting, broadcasting and recording of live broadcast only by himself at home. The live broadcast “Camera Technology” course given by Xia became popular among students for its clear framework, professional production, high originality, excellent content, clear picture and smooth signal.

Mr. Xia Guanxiang, who is the director of the technical department of the Public Channel of Zhuzhou Radio and TV Station before entering the college, began to study the realization, verification, and implementation of the live broadcast system technology from the end of January, 2020. The course was created from scratch. Until May 28, the course portal "course opening times" (page review) had reached 82,519. The three links of the resource construction, course content production, and course online live broadcast of the system course are independent of each other, and do not attach each other. The live broadcast platforms can be selected to facilitate the timely replacement of the platform when it is overloaded and severely stuck. It can enrich the teaching methods and help the teacher to ensure the teaching effect. Just one person can conduct directing, shooting, broadcasting, and recording at the same time, which can perfectly solve various needs of all kinds of teaching resources, such as signal switching, online live broadcasting, video recording, etc.. The teacher is both a "anchor" and a "director", that is, to achieve his own "live broadcasting and recording" by himself. During live broadcast, the sound picture is clear, the viewing is smooth, and it can be watched across multiple platforms.

To ensure the quality of online teaching, we need to constantly enrich the form of teaching. Xia Guanxiang mentioned that "We should broadcast the lectures in accordance with the production and broadcast standards of the TV industry, continue to build online courses with professional technology and diligent attitude, and strive to make them into high-quality online live courses."
