What is the difficulty of achieving triple play?

The so-called triple play refers to the exchange and dissemination of voice information, data information, news and entertainment information in an interactive form. The transmission of information is two-way, and China's current cable network 90 is a point sending and surface receiving, that is, broadcasting, and there is no uplink information. It can only be what you watch, and you have no choice, otherwise who will watch the advertisement?

We're passive. After the integration of the three networks, we are free to choose when we obtain information such as news and entertainment, that is to say, I choose what I watch. At the same time, it has the functions of voice, timely call, etc., and can also be like QQ multi-party conversation, game, chat, etc.

The cable network should realize the integration of three networks: the network transformation is now fiber-to-the-cell, one-way transmission, the terminal is a set-top box, the network is small, and there is no experience in information exchange and management. At present, the cable network is basically owned by the regional government, and there are big problems with funding and management.

Solving these problems is very difficult.

The telecommunications network should realize the integration of three networks: network transformation, now it is the first line, (but now it has gradually paved the optical fiber to the head of the building, further than the wired network), the signal is two-way transmission, the terminal is a computer, the network is large, and there is experience in information exchange and management. Both funding and management are very mature.

Now IPTV and CCTV's network TV are running on the Internet, but it is limited by the transmission frequency band of the first line, the effect is average, and it can be easily solved if the fiber is to the home.

Therefore, telecommunication networks have advantages over cable networks, or mergers.

Triple play refers to the integration of three networks, three networks integration is a generalized, socialized statement, at this stage refers to the integration of high-level business applications, manifested in the technical convergence, in the network layer can achieve interconnection, the formation of seamless coverage, the business layer on the mutual penetration and crossing, the application layer tends to use a unified IP protocol, are for the same goal gradually converge together, through different security protocols, to provide multi-level, diversified, personalized services, Finally, a set of O&M models compatible with multiple services in the network are formed.

The integration of the three networks has high requirements for the application and practice of technology, and it is also necessary to realize the interconnection of various network layers in the actual construction process. The integration of the three networks is widely used, covering many fields such as intelligent transportation, environmental protection, work, public safety, and safe home. In the future, mobile phones can watch TV and surf the Internet, TV can play ** and surf the Internet, and computers can also play ** and watch TV.

The three intersect with each other, forming a pattern of you having me and I having you.

In the "science and technology integration" model of the China Internet of Things school-enterprise alliance, the "triple play" is a typical manifestation of the gradual integration of technology and standards. "Triple play integration", also known as "triple play integration", refers to the mutual penetration and compatibility of telecommunication networks, cable television networks and computer networks, and gradually integrate into a unified information and communication network in the world, of which the Internet is its core part.

The integration of the three networks has broken the previous monopoly of radio and television in the field of content transmission and telecom in the field of broadband operation, and clarified the criteria for mutual entry - under the condition of eligibility, radio and television enterprises can operate value-added telecommunication services, basic telecommunications services managed by reference to value-added telecommunications services, and Internet access services provided based on wired networks; State-owned telecommunications enterprises, on the other hand, may, under the supervision of relevant departments, engage in the production of radio and television programs, the transmission of Internet audio-visual programs, and the retransmission of audio-visual programs for current political news.
