China Telecom Sichuan has launched the first commercial 4K ultra-HD iTV network service in China. It has teamed up with Huawei to release a 4K ultra-HD intelligent smart set top box, making China Telecom Sichuan the first telecommunications company in China to use 4K STBs for carrying video services.
By combining fibre broadband, 4K ultra-HD video capabilities, and a 4K ultra-HD network construction, the 4K ultra-HD iTV service aims to deliver better quality picture and smoother 4K video experience.
China Telecom Sichuan has adopted the H.265 video coding standard for a better user experience, and also deployed leading technologies to optimize the code stream, coding quality, delay, and algorithm complexity.
With 4K ultra-HD services requiring more intelligent processing than traditional service platforms, IP TV and CDN platforms have also been integrated to achieve intelligent acceleration, distribution, and scheduling to safeguard 4K services.
Additionally, 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 optimised to support 100M fiber to the home.
China Telecom Sichuan has also deployed an engineer-to-engineer network quality detection system to support visualised management of video services, which ensures the experience of 4K signals and thereby improves the user experience.
