The era of 4K video has come. Data from BI Intelligence can be seen: In 2014, 4K TV shipments reached 10 million units. By 2019, 4K TV shipments will reach 371 million units; in 2014, 4K video traffic accounts for 0.2% of the total. By 2019, the proportion of 1,4K video traffic will reach 21%. From the perspective of sales price and shipment growth rate, the average selling price of 4K TVs in the Chinese market decreased by 78% from 2012 to 2014. From 2013 to 2016, global shipments of 4K TVs will increase by 10 times. This shows that 4K video is ready to go.
The 4K video era hits
For a long time, video services have been positioned by operators as part of value-added services, but this has become outdated with the development of the times. With the continuous increase of broadband, operators urgently need to be able to embody services with high-speed broadband value. IPTV, especially 4K IPTV, has become a new profit growth point for operators.
With the proliferation of fixed and mobile broadband users, new carriers such as IPTV, Internet TV, mobile TV and other new services and smart terminals are growing rapidly. In order to enhance the value of broadband and respond to the competition of the Internet, telecom operators have made efforts to provide video services.
Judging from the progress of the industry, China Telecom has launched a "Gigabit-leading, 100-megabit-based" broadband strategy. Sichuan Telecom has adopted 4K as its basic business, and in October 2015, it has achieved the world's first million users 4K. Live broadcast; China Mobile has also launched 4K pilot sites in some cities; Internet companies such as LeTV, Sohu, and Iqiyi have all launched 4K film sources; Radio and television, multi-site radio and television plans to launch 4K services by the end of 2016. 4K video has become a new "blue ocean" for all parties.
On the China Unicom side, Tang Xiongyan, chief expert of the China Unicom Network Research Institute, stated that China Unicom adopted a “three focus†strategy: focus on the home Internet, focus on video services, and focus on platform innovation. The video service is a strategic basic business of the home Internet. It is the core business of the "Smart Wisdom" home application scenario solution, and it is also a key weapon for creating a full-service competitive advantage for home customers.
In 2015, China Mobile’s data traffic surged. The scale of data service revenue exceeded that of voice services for the first time, accounting for 52% of communication services revenue, and officially entered a new era of traffic. Duan Xiaodong, director of the China Mobile Research Institute Networking Department, said: "In the future, video will be the main force for the surge in traffic."
4K puts new demands on the network and CDN
The on-demand/broadcast service of 4K/IPTV requires high performance and low latency. It requires the support system to provide users with timely troubleshooting and response. This imposes very high requirements on the network speed and quality of the basic network. With high bandwidth, access bandwidth also needs to evolve to 50M/100M.
The attitude and requirements of users for the pursuit of 4K ultra-high definition has prompted more manufacturers to cater to the user's viewing experience. With the development of 4K ultra-high-definition technology, content providers, TV manufacturers, chip vendors, and licensees have also launched content and devices that support 4K ultra-high-definition video. Under this situation, carrier bearer networks have gradually become the bottleneck of 4K development.
Yang Kun, secretary-general of the Ministry of Industry and Information Industry Interactive Media Industry Alliance, stated that changes from ordinary video to 4K ultra high-definition video have brought new requirements to the CDN. 4K movies generally reach several tens of gigabytes of storage capacity, which is several dozen times that of ordinary movies. This places new demands on the storage capacity of CDN devices; the 4K user's on-demand code rate is equivalent to several SD users, with the increase of the video bit rate. The user video service experience is extremely sensitive to changes in network delays and fluctuations. The CDN provides video services to users, and 4K content needs to be buffered to the edge service nodes. This places high demands on the concurrent traffic of CDN devices.
Raising the support capacity of the CDN network is the most effective means to cope with the rapid development of video, in addition to increasing the network bandwidth. The trend of the evolution of operators' traffic pipelines towards intelligence and service also affects the development of CDN at all times. CDNs must balance their open service capabilities while integrating into the vertical system.
Integrate CDN into the future direction of CDN
Yang Kun said that the video business has become a key force for stimulating the continuous growth of broadband users, which has directly led to the rapid rise of the CDN industry. The integration of CDN has become a widespread demand for the industry, which will be a huge market space.
The China Communications Standards Association has conducted research on interoperability standards such as the CDN internal interface and the CDN security standards. “China's upstream and downstream industries need to further integrate resources, promote domestic standardization work, and further enhance the international standard discourse of the domestic CDN industry.†Yang Kun said.
According to Duan Xiaodong, the CDN will evolve in three directions in the future. First, by moving the edge of the CDN, the edge node will be closely integrated with the mobile network, and the node deployment position will sink closer to the user, requesting direct response at the edge and better response. After LTE commercial use, there is an explosive growth in traffic. Second, the OTT CDN is converged, and the existing video CDN and content network are gradually merged. The OTT CDN is used as a subnet of the entire network CDN to implement two-level scheduling through the whole network scheduling and local scheduling, and the future OTT TV service. It will be hosted by the content network. Third, multiple CDN interconnections, multiple CDNs are connected through open interconnection interfaces, and a wide-area CDN system with unified business logic is formed to effectively expand its own forwarding capacity and build a good ecosystem.
Fusion CDN becomes a loosely coupled content pipeline to the business. It can realize unified hosting of services such as Internet TV and Web page video, and effectively respond to Internet traffic, which will make the CDN boom again.
4K Business Development Cannot Be Ignored
While 4K ultra high-definition video brings users a good viewing experience, 4K's current industrial development issues can not be ignored. With the rapid development of video services, the major issues that restrict business development gradually appear, mainly in policies, platforms, CDNs, networks, services, and terminals. It is imperative to formulate a systematic development strategy to ensure long-term business continuity. development of.
In terms of policy, SARFT only authorized pilot projects in some cities, and non-pilot regions expanded the hidden dangers of IPTV storage policies. In terms of marketing, operators' social channels and e-commerce channels to expand video service capabilities needed to be improved, and industry video applications were weakly developed. Terminals, existing terminals Most of them are non-intelligent terminals and cannot support value-added services such as 4K and games. On the platform side, the IPTV platform functions and capacity are limited; CDNs and networks are too closed, and there is no Internet iteration, and the transition from the communication network to the video network is required.
In addition, judging from the current 4K concepts, most commercially available 4K products only focus on the hardware level, and 4K TVs are currently commercially available. However, only 4K services actually experienced by home users are handy. Vendors with rich video content resources can provide some 4K-based film sources, while some vendors with less content can only experience 4K pixels for users through some pictures. Users' perception of 4K is still very limited. The lack of 4K content has also been criticized.
Operators' initiatives to escort 4K services
In order to promote the rapid development of 4K services, Duan Xiaodong stated that China Mobile is vigorously building a "core network"-content network for traffic management. IDC and Cache systems have been deployed, and CDN networks will be developed in the future to jointly build a complete content network system. .
Since China Mobile launched its full-service business, PON broadband access networks and home broadband subscribers have been steadily developing and have been accelerating. They have achieved certain scale advantages and have laid a good foundation for the continuous and in-depth development of cable broadband networks and 4K HD services. “China Mobile has recently established a 10-fold plane with full 100G interconnect and ASON technology to adapt to a leap-forward development of traffic; a new architecture network for user access and data center interconnection will be built with ultra-100G technology in the long-term (2018-2020). "Duan Xiaodong revealed.
In order to strengthen the R&D strength of the 4K business and support the development of video services, China Unicom established the "China Unicom 4K Laboratory" in December 2015 to support TV services. 4K Lab has fully supported the marketing department, network construction department, operation and maintenance department, TV value-added center, cloud company and other provincial branches, and has basically completed the preparation of platform, CDN and terminal technical specifications. China Unicom also initiated the establishment of the "4K Ultra Clean Industry Alliance" with domestic major 4K equipment manufacturers, service providers and content dealers. China Unicom will decouple the IPTV service platform and CDN system, and implement five parts of the content management platform, service management platform, EPG platform, CDN and set-top box.
Speaking of China Unicom's plans for the next step in its video and 4K services, Tang Xiongyan stated that in order to ensure the continuous development of the TV video business, China Unicom will work on all aspects of TV development in accordance with the ten criteria. For example, in terms of content applications, the localization and value-added services of live broadcast services are intensively promoted, 4K ultra-clear video on demand, Wojia video, and mobile IPTV are promoted; on the service platform, unified video service platform specifications, clear construction processes, and realization of the North platform Decoupling, speed up the construction of a live broadcast platform in the south; build a converged CDN, support the development of the entire business, optimize the construction of a quality video support network; unify the 4K set-top box standard, unify the test and collection of set-top boxes, and stop the development of non-intelligent set-top boxes. With the continuous efforts of all parties in the industry chain, 4K business will surely usher in rapid development.
