Telecom network vendor Huawei has assisted China Telecom Sichuan to launch the first commercial 4K ultra-HD iTV network service in China.
This apart, China Telecom Sichuan will be the first telecommunications company in China to use 4K STBs – released by Huawei and China Telecom — for carrying video services.
By combining fiber broadband, 4K ultra-HD video capabilities, and 4K ultra-HD network construction, the new 4K ultra-HD iTV service promises better picture quality and smooth experience of 4K video, said Huawei.
4K STB enables customers to enjoy ultra-HD movies four times clearer than movies on HD STBs. The integrated 4K encoding, platform, CDN, network and 4K STB enable users to experience iTV services uninterrupted.
The 4K network bearer solution supports display and forecast for end-to-end video quality, accurate fault positioning and rectification in case of faults.
Huawei and China Telecom adopted the H.265 video coding standard for better user experience, and also deployed advanced technologies to optimize code stream, coding quality, delay, and algorithm complexity.
Speed acceleration for metropolitan and backbone networks has enabled the entire network to transmit 100G optical services and 400G Internet protocol services. The tail end network is optimized to support 100M fiber to the home.
China Telecom Sichuan has deployed an engineer-to-engineer network quality detection system to support visualized management of video services, which ensures the experience of 4K signals and improves the user experience.
