Hybrid access hardware platform and the development of the IP system synchronization, also produced in the monitoring structure of the turbulent transition (Specifically, from 2009 the transition period from analog video to digital video systems

During this period, many projects have faced a demand for access to high-definition video, many owners like to take this opportunity to mold rotation transformation of the original system, the original analog matrix somewhat abandoned, but because of the number of the original analog front-end larger, and still continue to use for some time, so owners often choose this program: the original analog video and new IP high-definition video or HD-SDI video need to be integrated into a unified monitoring system, unified switching, unified storage and management. Software server-based IP surveillance system is a solution, another solution is compatible with a variety of video signals and other types of business signals mixed access hardware platform

Existing analog matrix can only access analog standard definition video, such a hardware platform can not only access to a variety of ways (coaxial cable, fiber) analog video can also access the IP form of high-definition video and even HD-SDI video. If you want to achieve a unified switching and management of different types of signals, then this mixed-access hardware platform the kernel must be the digital device, which focuses on how the device's internal backplane video digital switching and transmission. Hardware on the market-access platform roughly divided into two categories, one is based on IP mechanism backplane switching mode, type of equipment is basically as a combination of equipment for video encoders and switches, analog video received platform on the board after modulus are converted into digital video, and can also choose compressed or uncompressed into the backplane, backplane exchange based on the transmission of IP mechanisms, all video must be packaged by IP mode switching, IP video all the shortcomings of the system, the hardware platform will have; a hardware platform backplane switching mechanism is based on an independent bandwidth slot switching technology, this platform for the exchange principle similar to SDH or OTN architecture, popular a variety of signal digitization (compressible or not compressed) into the backplane, the transmission of these data is packaged in accordance with the proprietary protocol, and each signal is assigned a separate bandwidth, guaranteed not to conflict packet loss, the hardware platform completely resolved the QOS in IP systems to maximize and ensure the stability of data transmission and exchange

Mixed access platform, this was born in the transition of analog systems to digital systems, hardware is just a transitional product? In my opinion, no matter what the nature of the video, as long as the access platform to exchange and transfer to digital, so regardless of the outside world is an analog video or IP video, or SDI video or other types of signals, the same platform so, just different bandwidth data stream just how effectively these data transfer and exchange is the core of the platform, So, even if the simulation system the transition to digital systems, hardware platforms can still be commonly referred to as the IP system to jointly build the future of video surveillance systems. If the exchange of this hardware platform is based on the IP mechanism, then it is a set of hardware of the IP system, but based on dedicated bandwidth slot switching technology hardware platform may be an advantage, after all, it solves the IP system is very difficult to solve QoS problems, to ensure stable and rapid data exchange

Currently, some domestic production USP is based on the time slot exchange independent bandwidth transmission hardware integrated access platform, has now been successfully applied in multiple Large projects
