Internet transformation is suitable for large-scale areas
From the perspective of current network construction, domestic network construction models can be divided into Internet IPTV and IPTV private network.
The Internet IPTV network construction method refers to expanding and rebuilding the original metropolitan area network to build it into a multi-service bearer network. From the perspective of bearer network technology, the network architecture and network deployment of the existing metropolitan area network are based on ordinary Internet services. As an overall consideration of IPTV services, building an efficient CDN network supplemented by a high-QoS multicast channel is the key to Internet IPTV bearer network technology.
The IPTV private network refers to the original metropolitan area network that carries the original broadband services, expands the access network, and transforms the BRAS. The access network carries both IPTV and PC services, which are separated at the convergence layer and enter different core networks.
Judging from the current pilot operations, the Shanghai Daning model is a relatively distinctive private network model.
Telephone traffic, Internet traffic and TV traffic are separated at DSLAM. The TV traffic goes to Daning IPTV operation center through IPTV private network, the telephone traffic goes to PSTN, and the Internet traffic goes to Internet through BRAS. Daning is actually a metropolitan TV private network, which achieves the purpose of using low-cost LAN high bandwidth in exchange for storage investment.
Compared with IPTV private networks, Internet IPTV has high construction costs, very complex multi-service bearing technology, and high network operation and maintenance costs. The services provided by private networks are relatively closed, with relatively low requirements for routing and control strategies, and reduced demand for high-end equipment. They are easy to manage and control, have good security, and are easy to expand.
CCID Consulting believes that it is more appropriate for mass users/industry users with relatively concentrated user groups and small regional areas to adopt a dedicated network solution, while for large-scale, cross-regional IPTV applications, the Internet transformation method is more appropriate.
New industries lead to competition for dominance.
IPTV operation models are generally divided into two types: telecommunications-led operation models and radio and television-led operation models. In the telecommunications-led operation model, telecommunications operators mainly control operations and management, while radio and television operators mainly provide content and licenses. In the radio and television-led operation model, telecommunications operations are in a relatively secondary position. The entire operation is controlled by radio and television operators, and telecommunications operators only provide broadband Internet support and operation and maintenance.
The above two models are abstractions of the real models. In reality, there has always been a conflict between radio, television and telecommunications, and the main root cause is the conflict of concepts. Radio, television and telecommunications are responsible for maintaining the national ideology and enriching the cultural life of the people. In the era of "content-oriented", the entire industry chain is viewed from the perspective of content. Radio, television and telecommunications must control both the starting point of the content (i.e. the content itself) and the end point of the content (i.e. the user). Telecommunications only provide a transmission channel.
However, for telecom, it is positioned as a full-service service provider, and is no longer satisfied with providing basic network resources. Therefore, it is an application platform that integrates SP/CP and users. Naturally, the operation and management of this platform should be controlled by itself. Radio and television are just a component of SP/CP for it.
It is the difference in positioning that leads to some conflicts in current IPTV operations, specifically conflicts over new business growth points and competition for dominance. From a national perspective, since the cross-entry policy is still unclear, conflicts can only be resolved or alleviated at the radio, television and telecommunications levels.
Three strategies to reduce conflict
CCID Consulting suggests that the following three strategies can be considered to reduce the conflict between radio, television and telecommunications:
⑴ Business content differentiation strategy
At present, most domestic IPTVs regard live broadcast as one of their basic services, but the traditional strength of radio and television is live broadcast. Therefore, the telecommunications department should actively avoid live broadcast services in terms of business content; and the bandwidth resources of cable TV networks are more than those of telecommunications networks. In terms of smooth broadcasting of TV programs, telecom IPTV is definitely inferior. The main disadvantage of cable networks is poor interactivity, so the IPTV promoted by the telecommunications department should pay more attention to interactive factors and focus on the development and promotion of non-traditional TV program services.
(2) Introduction of third-party operating entities
If we only rely on the efforts of radio, television and telecommunications themselves, I believe it will be difficult to reconcile the conflict between the two. The most feasible way should be to have a third-party operating organization to integrate resources, that is, to form a content + operation + network model.
However, since both radio, television and telecommunications are large state-owned departments or enterprises, the strength of the third-party operator must be matched. In addition, the two companies adopting a joint venture is also a solution.
⑶Adopt dual-mode access solution
For the cable network of radio and television, if live broadcast programs also use the telecom network, the cable network may face a catastrophe. Therefore, as a compromise, live broadcasts should use cable networks. After all, the bandwidth of cable networks has greater advantages. In addition, for telecom networks, the requirements for multicast are reduced, and network deployment becomes convenient. On-demand, time-shifting, non-traditional IPTV and other highly interactive services use telecom networks, making full use of the interactive features of telecom networks. In this way, the conflict between radio and television and telecom will be greatly reduced.
