Utility model content
It is advanced that the purpose of this utility model is to provide a kind of framework, with low cost, construction cycle is shorter, the distributed image processing unit of function-stable, realize the collection for multi-signal Source Type and coding, video window is opened in the such as selection signal source realizing traditional centralized splicing device, window superposes, on the basis of roaming etc., can processing signals source and display dispersion special applications scene, simultaneously owing to exporting between output device, between input and input unit, completely independent respectively between input and output, decrease the degree of coupling of equipment, the risk that the fault because of a certain equipment component causes total solution to lose efficacy can be reduced.
In order to achieve the above object, the utility model has following technical scheme:
A kind of distributed video splicing control device of the present utility model, comprise switch, several input nodes, several output nodes, several display devices, for controlling control device, several web cameras of display translation, described switch is connected with several input nodes, several output nodes, several web cameras, control device respectively, and several output nodes described are connected with several display devices respectively.
Wherein, described input node is the harvester of the signal source of DVI, VGA, the CVBS had based on TCP/IP communication.
Wherein, described output node does with DVI signal the output device exported.
Wherein, described control device is management server.
Wherein, described output device is the network flow-medium that decodable code is encoded by acquisition node or the network equipment, and with the output device that DVI or HDMI form exports.
Wherein, described switch is the network switch.
Owing to taking above technical scheme, the utility model has the advantage of:
1. the utility model realizes for the collection of multi-signal Source Type and coding, video window is opened in the such as selection signal source realizing traditional centralized splicing device, window superposes, on the basis of roaming etc., can processing signals source and display dispersion special applications scene, simultaneously completely independent respectively owing to exporting between output device, between input and input unit, between input and output, decrease the degree of coupling of equipment, the risk that the fault because of a certain equipment component causes total solution to lose efficacy can be reduced.
2. the utility model processor can accomplish that input and output all do not have restricted number in theory.
3, the utility model is cheap, realizes flexibly.
4, the utility model easily can tackle complicated scene; And in the scene of centralized displaying and collection, the utility model also has can to replace the performance of centralized processor.
5, from software view, the utility model, due to open framework, to the realization of software function, brings more flexibilities, can realize much centralized functions that cannot realize.

Embodiment
Following examples for illustration of the utility model and uses thereof, but are not used for limiting protection range of the present utility model.
See Fig. 1-Fig. 4, a kind of distributed video splicing of one of the present utility model control device, comprise switch, several input nodes, several output nodes, several display devices, for controlling control device, several web cameras of display translation, described switch is connected with several input nodes, several output nodes, several web cameras, control device respectively, and several output nodes described are connected with several display devices respectively.
Described input node is the signal source harvester of DVI, VGA, the CVBS had based on TCP/IP communication.
Described output node does with DVI signal the output device exported.
Described control device is management server.
Described output device is the network flow-medium that decodable code is encoded by acquisition node or the network equipment, and with the output device that DVI or HDMI form exports.
Described switch is the network switch.
The utility model provides the some devices being operated in tcp/ip communication agreement.These devices, comprise input node, output node and management server according to functional effect.
Wherein, described input node comprises for unlike signal source---such as VGA, DVI, CVBS---harvester designed respectively.When harvester accesses corresponding signal source, this harvester can carry out the coding of the real-time H.264 rank of specific code check to signal, and then with RTSP agreement by the video streaming after coding, and broadcast on network.See flow chart one.
Wherein, described output node accepts the control from management server, the stream signal that the network flow-medium address that decoding is specified by management server provides, and by image according to the size of specifying, position, transparency, hierarchical relationship, cuts out parameter, playing progress rate etc. and is combined into a road complete picture and outputs to display terminal.See flowchart 2.
