How to apply cloud computing platform to the radio and television industry under three nets

Overall, China's cloud computing development, and foreign mature cloud platform compared to the scale is still very small, operation is not mature, still need domestic enterprises to further explore. In our country, cloud computing development is also very swift and violent, our country enterprise first proposed "cloud security" concept, in the International cloud computing domain unique, has created the cloud security solution the precedent. But overall, China's cloud computing development, and foreign mature cloud platform compared to the scale is still very small, operation is not mature, still need domestic enterprises further exploration. Among them, the cloud computing technology architecture and business model is very consistent with the development of three network integration characteristics, in such a large background, the broadcasting industry application of cloud computing platform?

Network TV Cloud Platform

How to use the "cloud" in radio and television media

The "cloud computing" platform can be deployed in a variety of ways, for the broadcasting media, the most common is the "private cloud" and "public cloud" two ways, "private cloud" is the radio and television media to build and own the "cloud computing" platform, users use the local area network can access, and "public cloud" is by the relevant manufacturers to provide "cloud computing" Services that are typically accessed over a wide area network.

Radio and television media can create a "private cloud" in Taiwan, consolidating existing IT systems is one of the most noteworthy and practical options available today, as well as renting the "public cloud" as a complement to IT resources: for foreign or off-site branches, the "public cloud" of television rentals may be more economical than the purchase of actual equipment.

On the one hand, whether the "public cloud" or "private cloud" is used, we all need to deploy the application in the cloud through virtualization, which is a common practice for other industries to use cloud computing technology, but on the other hand, the radio and television industry has its own particularity, its business system needs to deal with a large number of video and audio files, And the radio and television media has a lot of special hardware and special equipment, not all business is suitable for virtualization, in response to this problem, we simply analyze the following:

1, can be deployed in the "cloud" applications mainly include:

High-density data computing applications, such as transcoding, streaming media services;

High frequency information processing applications, such as database, application server, etc.

Massive data storage applications, such as storage based on "cloud architecture";

Ordinary workstation applications, such as office, catalog search, news, simple audio and video clips.

2, the need for traditional equipment processing business mainly include:

Use baseband signal processing business, such as upload collection, studio broadcast, etc.

Must use the GPU processing business, such as stunts, subtitles, graphic packaging, GPU transcoding, etc.

High data throughput of the business, such as Multi-layer high-definition editing;

Other business with special requirements.

Some cloud architecture of broadcasting and TV business

Therefore, the existing business system of broadcasting media is integrated through "cloud computing" platform, the use of "partial cloud" of the framework is the inevitable choice, specifically, transcoding, network transmission, media inventory, streaming distribution services can be implemented in the "cloud", but the traditional upload collection, complex editing, graphic packaging, broadcast system, Studio systems, signal monitoring and other business systems still need to use stand-alone workstation equipment. For applications that are deployed in the "cloud", such as media catalogs, users can access the cloud general-purpose terminals, such as computers, handheld mobile devices, anytime, anywhere, and get the same experience as a local workstation. The significance of cloud computing to the broadcasting industry

Cloud computing can achieve the front-end unified management, its Super computing power, huge storage space these outstanding advantages, for the radio and television industry, the promotion of digital TV business, has important significance:

1, the data height can be managed, controllable

Cloud computing provides the most reliable and secure data management center, and all data is stored uniformly in front-end cloud servers. Radio and television operators only need to arrange professional server maintenance personnel to update and protect, you can achieve all digital TV business management.

2. Cost minimization of terminal equipment input

In the current mode of operation of digital TV, there is no good interoperability between different regions and different brand terminals, and the cumbersome system integration and upgrade work increase the cost of operation maintenance. So that the promotion of radio and television business needs to pay extraordinary human and material costs. In this case, cloud computing is the best choice for the radio and television industry, cloud computing power can be a part of the terminal equipment to move forward, so that the terminal device requirements to minimize.

3, suitable for the development of the three-network integration needs

With the three-network integration strategy, the future will form a full range of video services across the field of development. This involves the question of how to share between different user terminals. End users do not have to carry a dedicated device, any client device that joins the cloud computing service, such as a set-top box, PC, smartphone, and so on, can log in through the browser, continue to watch part of the movie or write half of the article.

Cloud computing These characteristics, so that the integration of the three networks after the depth of business promotion, network business operations became possible, in the context of the integration of three networks, with unlimited space for development.

Cloud computing in the radio and television industry application once the national policy level of support, will be in the digital TV business operations shine! Ultimately, whether cloud computing can blossom in radio and television will depend on the Top-down implementation, depending on the continuous exploration of all our broadcasters!
