The integration of the three networks and the mobile Internet have pushed video-oriented Internet applications to the foreground. In the application process that emphasizes the integration of multiple screens, Internet TV has become a key screen. As the core bargaining chip for the integration of the three networks in the radio and television system, how to push the content to the terminal accurately and quickly has become the key to competition.
Cloud computing, a rapidly emerging technology in recent years, is bound to occupy an important position in the triple play. Well-known telecommunications expert Hou Ziqiang recently said that server decentralized deployment is the most economical way for broadcast and television operators to achieve content transmission, and cloud computing will become the best way for broadcast and television operators to deploy in the region.
Challenge: Private network is not economical
According to the latest "China Radio, Film and Television Development Report (2013)" (Broadcast Blue Book), as of the end of 2012, a total of 7 units were approved to build, manage and operate an Internet TV integration platform, and 10 organizations were approved to provide Internet TV For content services, the number of Internet TV terminal users is close to 30 million.
Professor Hou Ziqiang, a well-known telecommunications expert, pointed out: Although it is said that running Internet TV does not require special support from operators, it also needs broadcast and television infrastructure support, including production platforms, but we have concentrated a large number of servers in one location and rely on the backbone of broadcast Internet transmission is the least economical method.
At the same time, the telecommunications industry is constantly advancing the virtualization process. There is no longer a variety of switches, but a unified hardware server and hardware platform to achieve various functions. At this time, the virtualization of the computing center will occur, and the virtualization of the data center will further be cloud computing. The next step is the virtualization of the network, that is, the network function virtualization that the industry is now retreating from.
In contrast to the radio and television industry, it was only in the 1990s that the digital TV era began, when the Internet appeared. Radio and television advocates the establishment of a private network for content transmission, but judging from the lessons learned from the telecommunications industry, today's broadcast and television must also go to the Internet, and must constantly revolutionize itself. The telecommunications industry has already put forward the slogan of going to telecommunications, how to deal with the radio and television industry, virtualization is a general direction, is to solve the Internet TV infrastructure on the basis of cloud computing.
Introduce cloud platform to build a new mode of content transmission
Take Netflix, the world's largest video production platform, as an example, it is a typical use of cloud platforms to provide virtualization of production platforms. Netflix has 36 million users. It can be said that 33% of the users in the United States belong to Netflix, but such a huge number of users do not have their own hardware platforms. It is to rent Amazon ’s cloud platform services. All the hardware is provided by Amazon. Established a global platform on Amazon's infrastructure.
Professor Hou Ziqiang believes that, compared with concentrating a large number of servers in one location, if we disperse the servers in various places, this is the most economical and best way. Today, the emergence of cloud computing provides a very good opportunity for us to develop Internet TV infrastructure and achieve regionalization.
For radio and television, cloud computing provides the most reliable and secure data management center. All data is stored in the front-end cloud server, and all user authorization information and program information will be stored in a highly fortified server group. Broadcast and television operators only need to arrange professional server maintenance personnel for update and protection, and can realize the management of all digital TV services at the front end.
Therefore, the emergence of cloud computing technology is a new development method that the radio and television department can consider to build the infrastructure of Internet TV. However, the construction of the radio and television cloud platform cannot fully replicate the Internet model, but should be integrated into the characteristics of radio and television according to local conditions.
