Cui Feng: digital TV platform to build Equipment Selection On (I)
Of: up to Beijing four times Cui Feng Communication Network Technology Co., Ltd.
China Broadcasting Analog TV industry is in an important period of transition to digital. Beginning in 2004, has actively promoted all provinces Cable television The overall translation work. Foshan has been completed, Qingdao, Hangzhou and other modes of establishment.
Digital TV System is a collection from the program, program Make , Program transmission until the client receiver must process signals digitally-end systems. Using digital technology not only makes a variety of television equipment was higher than the existing analog equipment technical performance, but also with analog technology can not meet the new features that make TV technology into the new era. Easy transfer of digital encryption, scrambling, digital transmission processing can enter the broadband integrated services digital network, to achieve graphics, data transmission, on-demand TV, TV shopping, interactive two-way communication transmission services, and multimedia communications, multi-functional, so that radio TV access to the rapidly age.
How to build a kind of security, stability, and give radio and television industry to bring value-added benefits that the platform is a simple and complex task. The reason is simple because the system's various modules are relatively clear. However, the choice of modules and the interface between a very complicated project, need to consider all aspects. Now, I am on a platform some personal views on shallow, we want to help.
1, CA system CA is the core of the development of digital television, her follow-up to the development of stability and capacity-building key to digital television platform, so the CA to provide companies with high demands.
First, CA providers must be able to long-term development of large corporations. CA's R & D and the continuous development of products, the annual after-sales maintenance requires a lot of capital investment, and CA is not a short-term investment products can be return, which is generally small companies can not reach, CA to provide companies must stand the test of large companies. Otherwise, select the CA small companies can also run in previous years, so when the CA returns a small company can not keep up to lend support to the maintenance of late can not be guaranteed, it would be a fatal blow to digital television.
Secondly, CA to provide companies must master the core technology CA has a strong R & D capabilities, to provide protection against future feature upgrades. When the business can not keep up the market demand, CA provider not to promote new features to meet Operation Operators.
Again, in order to protect the stability of the system, high-performance front-end hardware Server (Such as SUN's server) is necessary and should not use low-cost PC Machine, thus avoiding the use of PC, the situation of frequent crashes. Actually, CA compared to the entire front end into the input digital television platform, is much smaller. Imagine hundreds of thousands more into the system to ensure stability, eliminating the instability generated by the system dimension Care Workers As, the number of maintenance cost savings. In so doing we put hundreds of thousands more worthwhile.
Again, CA to be passed the test of time, because selection has been running a long time, the number of users and use cases and more CA systems.
Again, choose the CA system when selecting the third party Loader. In order to construct a general CA systems technical barriers and enhance the operator's replacement cost, use private Loader system, resulting in replacement Smart Card Must be manually recovered STB . So select the CA when the Loader to use third-party systems, enabling operators to CA through the air Loader replacement, without manual recovery set top boxes, greatly reducing the cost of replacement of CA.
Again, the smart card to choose to protect quality of imports cards on the market today, there are two card options: homemade cards and imported cards, homemade cards are cheap, but quality not guaranteed, first, poor technology, bad card rate, and second, reduce the difficulty of hacker crack, third because of low performance card features a small lead. Card made Import relatively expensive card, the difference in the scores of dollars, but the quality is guaranteed, CPU Speed, Memory Higher than other properties, to carry out value added services in security and hack another card to enhance and virtually zero probability of being cracked. Import cards from the performance improvement in solving more difficult to bring revenue to the operator point of view you have chosen to import hundreds of dollars card is cost-effective.
Again, the value-added point is the digital TV value-added services, value-added services a variety of flexible income protection for operators. CA support needs in addition to the most common monthly billing but also support the gold event PPV, N VOD PPV, TokenPPV, Mobile SMS on demand, prepaid card, CM return, Credit card Payment, opening the preview, two-way interaction and flexible business model.
Again, CA system must take into account system hot backup, when one server is down, will not affect the normal operation of the system.
Most times, select the CA Integrated consider when set-top boxes cost. CA to set-top box manufacturers manufacturers generally charge various fees, such as the hundreds of thousands to millions of entry fee, each tens of thousands of Test Costs and per Sell A set-top box more than a dozen paid to the tens of dollars per license fee, the cost per set-top box must be at least tens of dollars amortization. In the digital television platform, the set-top box is the largest part of investment, reduce the tens of dollars for each set-top box, the whole platform is a substantial savings. One of the few manufacturers can now remove some of the costs (such as the Norwegian Telecom, Conax, Beijing counted through).
2, SMS system SMS system that is digital TV subscriber management system, is a digital TV platform operations necessary software. SMS system reflects the operator's operating model and thought, master, management, operators, user information and billing data, is the digital TV platform of the core software. Select the SMS system to focus on the following issues.
First, the need for SMS providers are strong, this is because: 1, Digital TV in China has just started to explore the business model is not completely to form a fixed pattern, need to continuously develop SMS providers to meet the operational business model, which requires substantial capital investment in SMS provider, but a return is not visible, and therefore need to have strong financial strength. Second, as the business continues to develop, require development of SMS providers such as new as the new billing strategies, offers strategies for a specific time modules, which need to SMS provider has a strong R & D team to ensure a short time
