Description
Technical field
The present invention relates to technical field of video monitoring, relate in particular to a kind of image premonitoring method, Apparatus and system being applied in splicing system.
Background technology
Splicing system is widely used in municipal unit and enterprise, as the application of the formal occasions such as information issue, monitoring in real time, meeting.Existing splicing system as depicted in figs. 1 and 2, comprise tiled display equipment and the input card connecting successively, splicing switch card (switch card that splices use) and output card, input card 1～n converts splicing switch card to for the initial data of each input source 1～n can unify the data of processing, splicing switch card is under the effect of host computer or controller, create the mapping channel between input card and output card, then utilize output card i～j that some input source is carried out being presented at after relevant data processing and on tiled display equipment, complete splicing function.
As the platform of demonstration information in real time directly perceived, splicing system must guarantee the correct of displaying contents.Along with large-size screen monitors application popularization, front end signal source also faces magnanimity input and multiple format, in tradition splicing system, unlike signal source is presented on and controls interface with tabular form, every road signal source only replaces with letter symbol, operator is difficult in advance and real-time judgment signal source content, only could clear and definite information after large-size screen monitors show.If signal source sign is wrong or displaying contents is improper in important meeting or during simulating actual combat, after being presented to large-size screen monitors, error message will make a very bad impression.
In addition, in video-splicing application, input source is more and more, and user can not or unnecessaryly be presented at all input sources on tiled display equipment.The input source that those are not shown just need to show on other display equipment, the picture situation that user can each input source of Real-Time Monitoring, and according to picture situation, switch on tiled display equipment at any time.
By this, the present invention monitors input source picture disply on non-tiled display equipment function for user, we are referred to as premonitoring, for showing that the equipment of premonitoring picture is referred to as premonitoring display device.
Current premonitoring system and the method adopting have two kinds of output card single channel premonitoring and network code card multichannel premonitorings.As shown in Figure 1: it is upper that single channel premonitoring utilizes switch card Jiang Mou road input source to be switched to as the output card k of premonitoring function, realizes the premonitoring of Dui Yi road input source, if need the other road signal of premonitoring, an other road signal is manually switched on output card k.As shown in Figure 2: network code card multichannel premonitoring will need the data of premonitoring demonstration to be switched on network code card by switch card, and then the network switch outputs to premonitoring display device excessively.
In the design of premonitoring system, when user is concerned about input source number, image resolution ratio, frame frequency, be also concerned about hardware cost, the many factors such as occupancy, transmission bandwidth to splicing switching channel, premonitoring system must be weighed many factors.
Although the premonitoring system of the output card based on shown in Fig. 1 and the method adopting only take Liao Yi road switching channel, can only premonitoring one road signal, cannot meet the multiple input sources application scenario of premonitoring simultaneously.
In the premonitoring system of the network code card based on shown in Fig. 2 and the method adopting, the input of coding card is from the output of switch card, mean that premonitoring system has occupied the switching channel with premonitoring port number equivalent, because the quantity of switch card output channel is fixing and limited, when premonitoring input source increases, switching channel is occupied more, and the switching channel that splicing system can be used so will be fewer.
In sum, in existing scheme, the realization of multichannel premonitoring can take a plurality of switching channels, has limited the realization of a large amount of input sources of premonitoring simultaneously.
