摘要

在本文中，我们实现了一种算法，该算法可以自动切换移动现场节目制作的现场采集单元(FPU)中的总调制顺序，并通过实验室和现场实验评估其性能。我们正在研发用于移动直播4K/8K节目制作的大容量fpu，例如公路赛车直播。采用自适应传输控制，实现了恶劣环境下的稳定传输和良好环境下的高速传输。该交换算法有望扩大吞吐量的可变范围。我们在一个原型中实现了该算法，并通过实验室和现场实验评估了算法的运行。结果证实，将常规方法的2.79倍的通量可变范围扩大到3.40倍，并扩大了稳定传输区域。

[Paper] Field Experiment with FPUs for Mobile Relay Programs with Auto-switching of Total Modulation Orders

In this paper, we implement an algorithm that automatically switches the total modulation orders in a field pick-up unit (FPU) for mobile live program productions and evaluate its performance through laboratory and field experiments. We are conducting R&D on high-capacity FPUs for mobile live 4K/8K program productions, such as live broadcasting for road racing. Using adaptive transmission control, we aim for stable transmission in poor propagation environments and high-speed transmission in good ones. The switching algorithm is expected to expand the variable range of throughput. We implemented the algorithm in a prototype and evaluated the algorithm's operation through laboratory and field experiments. As a result, it was confirmed that the variable range of throughput, 2.79 times with the conventional method, was expanded to 3.40 times, and the stable transmission area was expanded.
