Problems solved by technology

When using the traditional method to display signal images, a D3d device object created must be bound to a window handle. Therefore, if you want to display 100 channels of signals, you need to create 100 D3d device objects. This method is extremely wasteful. memory resources

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] see figure 1 As shown, a multi-signal window display method includes the following steps:

[0024] Step 101, create a display window for displaying signal content, and the size of the display window is equal to the size of the desktop.

[0025] As a better embodiment, the area of ​​the display window created in the present invention may be {0, 0, M, N}, where MxN is the resolution of the desktop.

[0026] Step 102, create a D3d device object, and bind the D3d device object with the display window.

[0027] Step 103, acquiring the real position coordinates of each signal to be displayed on...

Abstract

The invention provides a multi-signal window display method and a multi-signal window display device. The method comprises the following steps: establishing a display window, wherein the size of the display window is equal to that of a desktop; establishing a D3d (Dynamic 3dimensional Display) equipment object, and binding the D3d equipment object with the display window; obtaining the position coordinates of each path of signals to be displayed on the desktop; calculating the size of the display area of the display window according to the position coordinates; rendering a signal source image to the display area corresponding to the display window according to the D3d equipment object, and displaying the display window on the top. According to the multi-signal window display method and the multi-signal window display device disclosed by the invention, the video memory resources are greatly saved, and the display of hundreds of paths of signal source images can be realized by using only one D3d equipment object; moreover, the establishment of large windows is quicker, and especially when a plurality of signal modes are switched for display, the display speed of signal content is several times quicker than that in the traditional method.

Description

technical field [0001] The invention relates to the field of splicing walls, in particular to a multi-signal window display method and a multi-signal window display device. Background technique [0002] In the field of multi-signal display of splicing walls, it is usually necessary to display hundreds or even thousands of video signals. In the traditional multi-signal window display method, each video signal must correspond to a signal window. Then, when hundreds of signal windows are displayed together, hundreds of signal windows of a specified size need to be created. [0003] In addition, for a processor based on a PC (Personal Computer, personal computer) architecture, using Direct3d (hereinafter referred to as D3d) programming technology for image display is a very mature technology. When using the traditional method to display signal images, a D3d device object created must be bound to a window handle. Therefore, if you want to display 100 channels of signals, you nee...
