Abstract

The present invention discloses a distributed automatic notification method for abnormality in remote massive monitors. If a data stream is not available, a disconnect prompt stream is generated. The data stream is converted to a continuous video. Then, the continuous video is divided into a plurality of single-frame images along the time axis, and each single-frame image is divided into a plurality of image grids. A plurality of pixels are next selected from each image grid. According to a plurality of image parameter values corresponding to the plurality of pixels, a statistical value of image grid parameter is calculated. Then whether an image grid is monochromatic can be judged according to the statistical value of image grid parameter. When a plurality of continuous single-frame images are judged to be monochromatic single-frame images, the color of the monochromatic single-frame images can be further judged.

determining that the connection of said monitor is abnormal if said color is identical to said disconnect prompt color; and
determining that said monitor is abnormal if said color does not comply with said disconnect prompt color.

7. The distributed automatic notification method for abnormality in remote massive monitors of claim 6 , and after said step of acquiring said data stream from said monitor if said data stream is available form said monitor and before said step of combining and converting said disconnect prompt stream and said data stream to said continuous video, further comprising steps of:
