Design and Research of Ultra High Definition Television Broadcasting System Based on 12G SDI Technology
With the release and implementation of the"Action Plan for the Development of Ultra High Definition Video Industry(2019-2022)",it is necessary to conduct in-depth exploration of 12G SDI technology in order to further implement the industry development strategy of"4K first,considering 8K",and improve the construction and operation efficiency of ultra high definition television broadcasting systems.The article designs an ultra high definition television broadcasting system architecture based on 12G SDI technology,analyzes the system's functional configuration and implementation,and discusses aspects such as signal source access conversion,video playback storage,broadcasting control,delayed broadcasting,and high standard definition simultaneous broadcasting.It is hoped that this can provide some reference for the design and development of ultra high definition television broadcasting systems.
