Wherein, described P gets positive integer. Client terminal receives the information of all premonitoring cards simultaneously, obtains premonitoring information and picture respectively from different premonitoring cards, then carries out splitting according to premonitoring information respectively and carries out premonitoring.
For example, it is assumed that there are 32 road video signal sources, Jiang Zhe 32 road video signal source is divided into two groups, every Zu You 16 road video signal source. First premonitoring card merges the image of first group of Zhong 16 road video signal source, in premonitoring information, indicate picture number and signal source passage corresponding relation list simultaneously, namely the passage number of the image opsition dependent arrangement of this 16 road video signal source is indicated, and the connection numbering of this width picture of this 16 tunnel signal combination. After premonitoring is stuck in the image of the video signal source generating first group, continue to generate the image of the 2nd group of 16 road video signal source. With reason, the 2nd premonitoring card merges the image of the 2nd group of Zhong 16 road video signal source, and indicates picture number and signal source passage corresponding relation list in premonitoring information. Client terminal receives premonitoring information and after download pictures, splits picture according to signal source passage corresponding relation and pre-defined resolving power, is applied to corresponding signal source premonitoring or windows in premonitoring. Client terminal is split image in an identical manner, completes the preview display of the 2nd group of video signal source.
