Description
Technical field
Wataru present invention, and video control technology, in particular to a dual network redundancy based on a centralized integrated video array Duoluleida video, television video control terminal in a multi-distribution and switching on the control method applied to military civilian control terminal field monitoring system for multi-channel television and multi-sensor Duoluleida video signals shared control.
Background technology
Along with improving constantly of social informatization degree; The demand that need implement integrated video monitoring in each field of the army and the people constantly increases; At the harbour, airport, highway communication, customs's frontier defense and safety-protection system etc. multi-field the multisensor video information is collected and is monitored become trend; Realization distributes and switching on many control terminals single kind multichannel or multiple type of multichannel comprehensive video information in real time; Share thereby reach video resource, for all levels of management personnel with the policymaker provides convenience, fast, effective service, be that the independent research comprehensive video distributes the target of controlling.Along with the high speed development of mechanics of communication I the centralized comprehensive video of former tradition distribute control appliance because its limitation of design can not well satisfy the demand of the many control terminals of system to the multisensor video monitoring.
The block architecture diagram of former conventional video distributing equipment is as shown in Figure 1.
Fig. 1 has only provided the configuration and the information trend of video distribution device interior when a control terminal is shared the video array, and other control terminal is identical with control terminal 1 with being connected of video distribution equipment with video source.
