UT Starcom Inc. Gu Rongjiang IPTV industry to promote the development of China's current IPTV standard specification work is being carried out in full swing, involving participation of the members of unprecedented scope, including telecom operators, content operators, IPTV equipment providers, IPTV systems integrator, IPTV technology providers, terminal manufacturers and so on. We all waved the banner of open standards, the most straightforward slogan is IPTV equipment interoperability, full of passion but is far too simple.
Standardized interconnection is really just an expression, if only to emphasize that interoperability is also limited in the past IPTV standardization of telecommunication network equipment based on the traditional idea of standardization. IPTV system complexity and the infinite possibilities of the future of business led to the standardization of equipment for the traditional thinking has been unable to meet the standardization of IPTV and development work needs to be used has now been proven and widely used for complex systems based on module standardized way of thinking. It is gratifying that the current formulation of IPTV standards have been thinking from the traditional standardized equipment turned the idea based on standardized modules.
IPTV complexity IPTV system is a multimedia and data services including integrated service platform, a mixture of real-time traffic and data traffic characteristics, specifically, involving the media codecs, transmission, distribution, storage, playback, digital rights management ( DRM), metadata (Metadata), electronic program menu (EPG), the browser (Browser) and other aspects, in the tradition characteristics of communication services and data services, while giving the traditional switching networks can carry real-time multimedia streaming services function, for the triple play out of a solid step forward.
IPTV system itself has these features make the platform carrying the future of the business has unlimited possibilities, on behalf of the huge market potential and opportunities, it also means the IPTV system to face the upcoming possible expansion; the system architecture is reasonable and the standardization of the module is the IPTV system and the key to industrial development, which is why only emphasized the slogan of equipment interoperability reasons too shabby.
Interoperability and standardization is not equivalent to open
IPTV vendors all claim that their devices will be standard and open, or even by claiming that its own front-end system with several different types of set-top box interoperability and can support; but this is still too simple, even confused with suspected deception. Is
interoperability and standardization is equivalent to open it? An obvious fact, Microsoft's IPTV system with multiple vendors, interoperability IPTV terminal manufacturers, but Microsoft's IPTV system is what we call a closed and not open. The IPTV terminal device merely a certain built-in software module to fit with the front-end system, it was claimed that some manufacturers are standard for the entire device and open, such behavior is undoubtedly the market behavior is just simply can not be standardized and open equate sex.
However, if the same is reasonable, in the current status of the domestic IPTV, the various devices can not be good interoperability does not equivalent to non-standard and not open.
IPTV terminal device manufacturers to assess the progress of standardization and open capacity
We all know, IPTV terminal equipment standardization and openness in addition to the hardware input and output, the highest concentration is reflected in the built-in software. Reasonable that interoperability is the IPTV system embodied in the specific application and technical aspects of the message definition; the true standardization and openness are more reflected in the design and basic application components and middleware level. Leaving aside the specific technology aside, IPTV standardization of terminal equipment and open ability to progress is reflected in the final product itself above vendors, and can be assessed by the following principles.
First of all, if manufacturers have to provide middleware or third-party development kits for the capacity. Middleware software has meant that manufacturers in the design and implementation of already mature, IPTV terminal device built-in software modularity, hierarchical, and have a good portability and secondary development capacity; and transplantation, and is open to secondary development of the basic essential features, or may be closed tightly coupled system.
Second, firms self-developed hardware platform for IPTV terminal devices and system platforms are diversity and cross-platform. We know now the mainstream of IPTV terminal hardware platform includes SOC, DSP, x86 platform, the corresponding mainstream system platform including Linux, WinCE, vXworks, PSOS, TiBIOS so. If the product contains a variety of hardware platforms and system platform means that IPTV terminal device with built-in software has a common basis for application of standardized components or middleware level. Can be a number of hardware platforms and system platform support components, usually a common industry standard protocols and technologies such as TCP / UDP, RTP / RTSP / RTCP, TS / DVBSTP, HTML, XML, J2EE, etc., all the future various application requirements can apply through the basic components or middleware seamless implementation and change.
Finally, the IPTV terminal device manufacturers to support the integration of third-party application systems software. It can integrate third party applications is the IPTV terminal middleware support for plug-in authentication capabilities. Support plug-ins and share pieces of a flexible middleware platform to support both IPTV system terminal equipment to upgrade the business requirements, but also enhanced and independent third-party value-added business system docking capability, such as the standard G-Cluster games business.
IPTV Middleware is the key and foundation for standardization
Both the terminal device or front-end system, IPTV IPTV standardization must consider and meet the business requirements and technical characteristics. From the perspective of architecture standards, we must divide the domain, level, function modules, information processing object and its interactive interface. On the module functions / data definitions and interface definitions is an important part of the standard. In addition, we must consider the performance standards (requirements), this standard is to ensure a consistent environment can test the performance of different products good or bad.
From a business point of view, IPTV has the ability to multi-service convergence, convergence at the network level broadcast TV (LiveTV), time-shifted TV (Shifted-TV) and on-demand television (VOD), to provide customized, localized, interactive audio and video services; as a high-capacity, scalable, high availability computing, storage, I am a professional writer from Mp3 Player Manufacturers, which contains a great deal of information about animated christmas decoration , childrens christmas stockings, welcome to visit!
