The Chinese electronics giant Huawei and media company China Telecom Sichuan have spent the last three years working jointly on the creation of a commercial 4K ultra HD iTV network service on the Chinese mainland. This has finally reached fruition and as of The last day of 2014, the network went live to subscribing customers.

The two corporations have used the HEVC (H.265) video coding protocol to transmit 4K signals to a smart TV Set-Top Box that delivers 4K content to the UHD TVs of subscribers.

Furthermore, the two companies have integrated intelligent acceleration, distribution and scheduling into the Internet Protocol Television (IPTV) and Content Delivery Network (CDN) platforms of their service in an effort to safeguard the stability and efficiency of their new 4K content delivery service.

According to Both Huawei and China Telecom Sichuan, their 4K ultra HD metropolitan backbone networks enable them to transmit a whopping 100 Gbps of optical services along with 400G IP services. As for the tail network that delivers fiber to subscribers’ homes, it can manage 100Mbps of broadband.

These are truly excellent broadband connectivity speeds that go way ahead of the majority of services available to homes in the U.S or even much of the developed world. Given that China is currently the worlds single largest market for 4K TVs with a 4K penetration of at least 10% of the overall TV market, the need for ultra HD content delivery is certainly a major market force that will only grow in the next few years.

Currently, the majority of 4K ultra HD content that is reaching consumers on various markets in North America, Europe and Asia comes in the form of streaming movies and other entertainment brought to TVs via direct web connections or VoD set-top boxes.

The amount of terrestrial broadcasting concerns that are delivering 4K media is still very small and most major media companies are just starting to release the first trial runs of their 4K broadcasting services.

One of the most advanced efforts currently being developed is a massive project in Japan to create constant nationwide 4K content delivery to at least two different TV channels for all subscribers by 2016.

And in the U.S, the broadcasting giant DirecTV has launched two new satellites that they hope to use for widespread satellite transmitted 4K content delivery to their subscribers by mid-2015. This broadcasting service is even expected to include live sportscasts in full ultra HD.
