On May 9, Huawei with CCTV (China Central Television) and China Television successfully completed the first 4K live streaming test on a 5G dual band convergent network in Beijing.
According to Huawei, compared to previous fixed point 4K live streaming tests, this test has successfully expanded the application scope and scenarios of 4K live streaming and takes another step towards 5G commercial use.
The transmitted 4K video had a resolution of 3840 x 2160 pixels and a frame rate of 50 FPS (frames per second), and to deliver a 4K footage requires a large amount of bandwidth and 5G the transmission of the 5G network can reach up to 10 to 100 times higher compared to the 4G network to deliver the bandwidth required for 4K streaming, says the company.
Huawei said the test verifies that the 5G network of China Mobile can effectively support 4K UHD live streaming of CCTV at a rate of 40 to 60 Mbit/s in mobility scenarios.
The company detailed that this solution helps transmit 4K UHD live video single to the CCTV headquarters through 2.6 GHz and 4.9GHz frequency bands with smooth and stable 4K video signals were observed during the test.
