The China Media Group, China Mobile, and Huawei successfully completed the first UHD live streaming verification through a real end-to-end 5G network slice. This is also the first live streaming slice on the 3GPP-compliant 5G SA network. This test uses the E2E 5G SA network slice provided by China Mobile and Huawei.

This slice is dedicated to provide the CCTV 4K live streaming services with the ultra-high bandwidth and ultra-low latency. The test personnel use 4K cameras to shoot videos in the outdoor field of Dong Zhi Meng of China Mobile Beijing. The video streams after being encoded and compressed are backhauled to the 4K TVs through the 5G SA network.

The test verifies that the network slice for the CCTV live streaming effectively provides the ultra-high bandwidth for live streaming services. The smooth, clear live streaming with high-priority assurance is ensured when traffic increases sharply on the RAN, transport network, and core network. After the test, the three parties will continue to deepen cooperation.

They plan to explore more application scenarios and slice types under mobile environment in the phase-2 test. This further promotes the commercial verification of 5G in media.
