Wireless video transmission technology plays an important role in space launch activities. For example, during the launch of the Shenzhou series manned spacecraft, the Central Radio and Television Station achieved real-time live broadcasting of the launch process through advanced wireless transmission technology. These live broadcasts not only include the shocking moments of rocket launches, but also cover multiple key scenes such as launch towers and command halls, providing viewers with a comprehensive and multi angle viewing experience.

In October 2024, the joint experimental team led by the Zijinshan Observatory of the Chinese Academy of Sciences successfully realized kilometre terahertz/submillimeter wave wireless communication transmission of high-definition video signals based on superconducting reception in Xueshan Ranch, Haixi Prefecture, Qinghai Province. This is the first time internationally that high-sensitivity superconducting receiver technology has been successfully applied to long-distance terahertz wireless communication systems, with a transmission distance of 1.2 kilometers and a signal transmission power of only 10 microwatts. This experiment lays a key technological foundation for the development of future space/air to ground high-capacity terahertz communication.

With the rapid development of satellite Internet technology, wireless video transmission is increasingly used in satellite communications. In recent years, China has successfully launched multiple communication technology experimental satellites and Beidou navigation satellites, which not only enhance China's satellite communication capabilities, but also provide more stable and efficient network support for wireless video transmission. For example, in the construction process of the Beidou satellite navigation system, wireless video transmission coverage to remote areas has been achieved, providing strong support for emergency rescue, disaster monitoring and other fields.

Driven by 5G and future 6G technologies, the speed, quality, and stability of wireless video transmission have been significantly improved. The Ministry of Industry and Information Technology and other relevant departments actively promote the support of frequency use demand in 5G, Internet of Vehicles, satellite Internet and other fields, and actively participate in the activities of the International Telecommunication Union, contributing Chinese wisdom and solutions to global spectrum division and sustainable development and utilization of satellite orbit resources. These efforts provide broader space and opportunities for the development of wireless video transmission technology.
