Abstract

Ultra-high definition, network convergence and content association have become new trends in the development of global broadcasting and television technology. In order to actively respond to changes in the consumption patterns of audio-visual media and changes in the mode of communication, the establishment of a new generation digital television broadcasting standard system in China will effectively guide the innovation and development of mainstream cultural media and accelerate the upgrading of the entire machine manufacturing industry. To this end, this article describes the development history and technical characteristics of the US new generation wireless digital television broadcasting standard (ATSC 3.0) that was developed this year, and the current development of global fifth-generation mobile communication technology (5G) standard that is being worked out. Combining China’s national conditions, this article proposed the development needs, development directions, and key technical proposals for the new generation wireless digital TV broadcasting in China.
