    "abstract": "The China Media Group (CMG) finished building its 8K UHD TV-relevant production and broadcasting system in early 2022 by innovating the application of 8K UHD TV production, transmission, playout, and presentation. On January 24, CCTV-8K, the CMG's 8K ultra-high definition channel and the 8K UHD “Hundred Cities Thousand Screens” public large-screen project, both launced simultaneously. — The CMG has improved its ability to transport 8K UHD signals by developing an IP UHD routing master control system using COTS routers as the primary switching equipment. The contribution of 8K UHD signals for CMG during the Beijing 2022 Olympic Winter Games was successfully accomplished by this system. The practices and technologies used in the contribution of 8K UHD IP signals are introduced in this paper.",
