摘要

8K节目的AV （Audio and Video）内容的大小是4K内容的4倍，为观众提供了更理想的视听体验，同时对文档准备和处理、信号传输、调度的能力和效率提出了更高的要求。然而，由于现有的广播系统架构受到效率、成本等因素的限制，难以满足8K广播业务的高鲁棒性要求。本研究设计了一个8K超高清（UHD）电视节目播出方案。验证结果表明，该方案具有高质量、高效率和鲁棒性。特别是在研究中，首先将文件格式归一化模块置于广播区而不是文件准备区，并在信号传输区设计了全ip信号JPEG XS的低压缩传输方案，提高了方案的效率。其次，为了减少对广播业务鲁棒性的影响，对广播核心组件的广播控制逻辑进行了优化。最后，实现了一系列8K电视节目广播系统，并对其性能进行了验证。结果表明，该系统满足高质量8K AV广播系统的效率和鲁棒性要求，具有较高的实用性。

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

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.
