As The 5G layout of China’s radio and television continues to accelerate, radio and television operators across the country have carried out edge cloud construction and business exploration. As a key link in 5G network architecture, edge cloud has the technical characteristics of wide coverage, low latency and large bandwidth. It is the “channel” for the construction of smart radio and television, and has a significant impact on the future development of 4K/8K ultra HD video, VR/AR/MR, cloud games, immersive live broadcasting and other businesses. Therefore, the application of edge cloud in the radio and television industry in advance is far-reaching.

The use of cloud set-top box benefits many

In the broadcast live network, there are a large number of TV set-top boxes, some of which may lack performance and cannot meet users’ changing audiovisual needs by deploying new business applications. By deploying the integrated system architecture of “cloud-edge-end”, the computing capacity of audio and video processing is decoupled from the terminal to the edge cloud, and new services are released in the edge cloud in an agile and iterative manner, quickly matching user needs. Through the twin computing service based on the edge cloud, the fluidization instance can be run on the edge cloud, and the customer’s control instructions can be transmitted to the shadow device on the cloud, and then output to the terminal for display through the fluidization technology.

The value of this application is also very obvious: for set-top box customers, they can run the latest application on the terminal, because image encoding and decoding, rendering and so on can be carried out in the cloud, so they can experience clearer video services; For radio and television platforms, they can provide rich applications without upgrading equipment in batches, and greatly reduce costs while developing their business.

360°+ immersive HD live broadcast creates a brand new extreme viewing experience

In large sports events and live concerts of stars, a large number of fans will enter the venue, and many of them can not even get tickets, some can only buy standing tickets at the edge, which will face a series of problems such as poor on-site experience. Relying on edge cloud technology, the event organizer introduced 360° free viewing Angle, VR/AR, 4K/8K ultra HIGH definition and other innovative technological means into the live video broadcast, so that the audience sitting in front of the screen can experience the “immersive” live level viewing experience.

During live broadcast, videos are aggregated by video collection equipment and uploaded to the edge cloud node nearest to the scene. Video data is distributed, spliced and calculated through the edge cloud. In this way, the consumption of network bandwidth for a large number of video data distribution can be avoided, and the transmission delay can be greatly reduced. Video image data can be calculated at the nearest location, which enables the deployment of more cost-effective and smaller video capture equipment. Meanwhile, edge cloud can take into account both wired and wireless access modes and support mobile and outdoor live scenes, making the mode of live broadcasting more flexible.

Cloud-based video content distribution makes the platform business more resilient

When providing video program resources to users, each radio and television operator needs to distribute and transmit through a large number of self-built video content distribution nodes to improve content service quality for the sake of security and operation. However, the current video distribution nodes are generally deployed in provincial and municipal computer rooms. Although the coverage is wide, there is still a long distance between them and users, especially in places with large personnel density, and the service experience still needs to be improved. By using edge cloud technology, cloud-based video distribution nodes can be deployed closer to users to achieve technological upgrading of radio and television platform.

Edge cloud standardized technology supports wired and wireless access, enabling users to greatly enjoy cloud-based video distribution services and convenient experience of watching videos. Based on the technical base of edge cloud, the radio and television video distribution platform is more flexible, and the platform operators no longer have to worry about business expansion. At the same time, it can effectively reduce the processing load and bandwidth pressure of the central cloud.

In addition, according to their own business development needs, radio and television platform operators can choose to rent third-party edge cloud resources to flexibly deploy their own business, reduce project CPEX investment, and focus on their own business development.

Cloud game every TV big screen seconds change game machine

As we all know, the development of cloud games depends on the construction of network, cloud computing and other infrastructure. And broadcasting has hundreds of millions of home TV screens, the future will be the best platform to achieve cloud game business quickly landing.

Cloud game “cloud – edge – end” deployment model left in closer to the game players to deploy a large number of the edges of the cloud gaming service node of cloud, the cloud gaming platform based on customer location and application characteristics, quick select a node is most suited to the edge of the cloud, produce a virtual device, the game after the user access to the edge of cloud node, instructions sent directly to the virtual terminal, The data processed by nodes will be sent to players and users by streaming mode to realize local processing of game data. The delay of edge side is controlled within 10ms, which greatly improves the game operation experience.

In the future, players will no longer have to worry about the configuration of game consoles. Any large screen of home TV can realize all kinds of hyper-real games of AAA titles in seconds, AR/VR immersive experience and 360° panoramic interaction, which is a new experience brought by edge cloud.

Integrated media cloud platform to improve production efficiency

With the help of edge cloud resources, the radio and television media business platform can realize second-level distribution and flexible control of national computing power, and significantly reduce infrastructure expenditure and operation and maintenance costs. The flexible, unified scheduling and extremely simple operation and maintenance capabilities of Edge Cloud help the whole life cycle of radio and television media content production, management, distribution and consumption, quickly build digital infrastructure, expand video applications and promote experience upgrading. At the same time, the edge cloud supports the distribution of Intranet traffic of broadcasting and television, and improves the transmission efficiency comprehensively. Media asset data can be uploaded to the cloud with one click, edge view can be stored and processed, and computing capacity can be expanded flexibly, making computing power intelligence at your fingertips.

In addition, media production, storage and distribution all run in the cloud, exploration may expand the boundary, application prospect is very imagination.

Edge cloud will play a key role in the future development of the broadcasting industry. The digital infrastructure of cloud side and end collaboration will enable innovative fission technology for smart radio and television. Ali cloud will take the difference of radio, film and television planning as the guidance, from the edge of cloud standards, platform construction, technology research and development, ecological sharing, etc., in combination with 5 g and the existing network resources of radio, film and television, dig deep edge of cloud in the value of network audio and visual field, to speed up the edge of cloud related applications fall to the ground, to promote better and faster development of radio, film and television industry.
