8K Ultra HD TV broadcast system: Challenge, architecture and implementation

Abstract

The size of the Audio and Video (AV) content of the 8K program is four times larger than that of 4K content, providing viewers with a more ideal audiovisual experience while placing higher demands on the capability and efficiency of document preparation and processing, signal transmission, and scheduling. However, it is difficult to meet the high robustness requirements of 8K broadcast services because the existing broadcast system architecture is limited by efficiency, cost, and other factors. In this study, an 8K Ultra-High-Definition (UHD) TV program broadcast scheme was designed. The verification results show that the scheme is high quality, highly efficient, and robust. In particular, in the research, the file format normalizing module was first placed in the broadcast area instead of the file preparation area, and the low-compression transmission scheme of the all-IP signal JPEG XS was designed in the signal transmission area for improving the efficiency of the scheme. Next, to reduce the impact on the robustness of broadcast services, the broadcast control logic of the broadcast core components is optimized. Finally, a series of 8K TV program broadcasting systems have been implemented and their performance has been verified. The results show that the system meets the efficiency and robustness requirements of a high-quality 8K AV broadcast system, and thus has a high degree of practicability.
