Problems: the need for IPTV Middleware?
Multimedia application platform middleware approach commonly used to achieve, GEM is now widely used middleware standards. There is also MPEG Multimedia Middleware. Currently, GEM-based development STB At least 10 million units. More mature European commercial middleware products OpenTv of EN2, Liberate's TVNavigatorforDTV, Enreach the EnreachTVforDTV, CanalPlus the Mediahighway, and NDS's NDSCore so. According to statistics, China's CCTV and provincial TV station Have used these middleware products.
Although the above are based on the home network middleware, design, and are used in Digital TV STB On, it seems that China's current IPTV is not at the main operator. Undeniably, however, many of the current IPTV set-top box digital television set-top boxes by migration and transformation through the years, such as changing the set-top box for access authentication, change the system module; Moreover, DVB -IPI framework applied to the field of telecommunications will not have much difficulty. In short, the middleware implementations and platforms for IPTV terminal for both a good choice because based on middleware to develop a variety of applications, but anyone can be developed based on it.
In fact, the middleware technology has been widely applied to all walks of life. A variety of operating systems, it is essentially a middleware. Such as Windows operating system, underlying it all PC hardware, storage devices shield up, so the above applications do not need to know the details of the underlying equipment. Meanwhile, Windows also provides a variety of interfaces and business development package, so only now colorful, personalized Win-dows application. The success of Windows, from the side that meets the development needs of the middleware is very important. I believe that with the continuous development of technology and hardware costs continue to decrease distress IPTV middleware platform, the development of terminals and the various negative factors will be gradually reduced, IPTV middleware will play an active role in future applications. So, who control the commanding heights of industry, who will win the initiative, Windows success is a typical case.
Issue 2: IPTV set-top box to "exchange"?
People often say that the future of IPTV set-top box to put in the mall, no one will buy a set-top box to take home, plug in the power, and the TV connected to IPTV programming can be seen, this is "interoperability." In fact, the "exchange" has three levels of meaning.
First set-top box plugged in and connected with the access network and equipment, set-top box through the service platform certification authentication, if adopted, would consider it a "interoperability", and this is a network-level interoperability;
Second, in the first case, based on the most basic services to achieve interoperability (such as broadcast, EPG display, etc.), as telephone call after telephone line plug as (only completed the initial telephone call features );
Third case of "interoperability" means in the second case basis, through the set-top box to watch any program, any subsequent payment to enjoy their content, this situation is also divided into several types. Thus, most people call "interoperability" is the third case of exchange.
"Interoperability" is a business model, performance and cost, use, needs and other related issues. Therefore, under different conditions, "interoperability" of the extent and scope vary. To illustrate the problem by application of two typical cases to illustrate a world in the use of telephone, the other is in use worldwide PC.
We all know, a phone to get to any corner of the world, plug in telephone line to a telephone call with any. Of course, it can only provide phone function. In order to provide more functionality, you need intelligent network. Visible, the global exchange to sacrifice the cost of its functions. Enhancements, increased business, to pay more in costs.
