Research And Design On Reliability Of Chongqing Cable Digital TV Interactive Platform System

2006 is our country broadcasting system "the digital development year" and "the industrial development year" also is our country vigorously carries out the cable TV from the simulation one year which transforms to the digital whole. Digital television interactive platform system tries to find out which in the advance(IPTV) and its increment service system, obtains the more and more wide spread application.This discusses mainly in the software engineering theory foundation, carries on the Analysis and the research using the software engineering method to the IPTV system, then carried on the comprehensive elaboration to it.The Chongqing digital television IPTV system is the distributional system which develops based on the module, and the integrated multitudinous application service, the software and hardware all has the very high extension. Because this system union digital television "the Chongqing pattern" in domestic belongs first time applies to the digital television domain, to the system and the hardware request, as well as to person machine interactive contact surface TV Portal and the content choice all is one bold attempt, fully conducts the research using the software engineering method to the item.Combine Chongqing cabled T.V. IPTV the need of the system. The distribute type adopting to develop according to the distributional system, and integrate numerous application services, make the software and hardware all have very high expansibility. In unifies when the distributional IPTV system carries on the reliable design, separately from system hardware and software two aspects to system carries on design. In the hardware reliability design aspect, uses the fault-tolerant redundancy design as well as carries on the hardware condition inquiry using the network correspondence mechanism. In the software aspect, uses to each processing line regulation condition set point monitoring, when the line regulation appears the breakdown can restore or again open, enables the line regulation to be able normally to move.In the reliable design foundation, completed the distributional IPTV system reliable realization. Indicates through the performance analysis, the research achievement and describes the design mentality and the realization method is reasonable, is practical feasible, has the certain reference value regarding the similar distributional IPTV system development.
