Processing method applicable to network video monitoring of digital light processing (DLP) multi-screen splicing display wall

The invention relates to a processing method applicable to network video monitoring of a digital light processing (DLP) multi-screen splicing display wall. In the method, each display unit is provided with a built-in personal computer (PC) which performs single-image and multi-image signal processing on a remote-end IP camera signal, and the processing process comprises the following steps: a network camera is started; the display unit of the built-in PC is started; the built-in PC in the display unit automatically starts a client; the display unit monitors and plays the camera signal; a built-in splicing processor of the DLP multi-screen splicing display wall finishes image splicing and amplifies, minifies and moves the signal; the DLP multi-screen splicing display wall displays the processed signal; and multi-channel signals are displayed by repeating the steps. Compared with the prior art, the method of the invention has low cost, is simple in construction and can ensure infinite increase of the number of
