China Telecom Sichuan in partnership with Huawei has announced the successful launch of the 'first' commercial 4K ultra-HD iTV network service - iTV service - that comes with a 4K ultra-HD intelligent smart set top box (STB) on fiber broadband in China. Both companies first began their partnership to develop IP video services three years ago and have since developed an end-to-end integrated 4K encoding, platform, CDN, network and 4K STB.
With the 4K ultra-HD video capabilities, the new ultra-HD video service promises customers four times clearer viewing compared to movies on HD STBs and smooth experience of 4K video. According to a statement by Huawei, they have specially adopted the H.265 video coding standard for a better user experience, with end-to-end integration to achieve intelligent acceleration, distribution, and scheduling to safeguard 4K services. Additionally, speed acceleration for metropolitan and backbone networks have enabled the entire network to transmit 100G optical services and 400G Internet protocol services, added Huawei.
