Problems solved by technology

[0002] In the existing signal display control method and preview method, when it is necessary to preview the images of multiple signal sources at the same time, multiple windows will be opened in advance in the control software, and the windows will be configured to determine the display resolution and display position of each window , associate each window with a visual signal, and establish a mapping between each window and the signal source device. From the perspective of the use of steps, this is cumbersome; the configuration is not refined enough, and the overall efficiency is low
[0003] Aiming at the above-mentioned problems in the signal display control method in the prior art that the steps are cumbersome, the configuration is not refined enough, and the overall efficiency is low, no effective solution has been proposed yet

Embodiment 1

[0047] Embodiment 1 of the present invention provides a signal preview method, which is applied to the host computer, see figure 1 A flow chart of a signal preview method shown includes the following steps:

[0048] Step S102, receiving configuration information, and switching the display mode of the window to include at least two independent sub-display areas according to the configuration information;

[0049] Each sub-display area is used to preview the visualized signal sent by the peer device or the node device and the signal source device respectively. The window is used to preview the visual signal sent by the signal source device; before the user performs preview related operations, the virtual display screen of the software interface needs to be pre-configured on the host computer, that is, the window in the virtual display screen is divided into different sub-displays area. The number of divided windows is not fixed, and the number of sub-display areas divided by e...

Embodiment 2

[0083] Embodiment 1 of the present invention provides a signal preview method, which is applied to the control unit of the service processing node, see Figure 4 The flow chart of another signal preview method shown includes the following steps:

[0084] Step S402, receiving the control instruction sent by the host computer.

[0085] The control unit receives the control instruction sent by the host computer, and the control instruction includes the address of the visualization signal corresponding to the control of the signal source and the resolution information of the visualization signal. The control command may also include picture quality option information.

[0086] Step S404, analyzing the control instruction, and sending a visualization signal return request to the service processing node where the corresponding visualization signal is located according to the analyzed control instruction.

[0087] The control unit does not directly control the signal source equipme...

Embodiment 3

[0104] Embodiment 3 of the present invention provides a signal display control method, which is applied to the software side of the host computer, see Figure 5 The flow chart of a signal source display control method shown in the signal display control method includes the following steps:

[0105] Step S502, receiving configuration information, and switching the display mode of the window to include at least two independent sub-display areas according to the configuration information.

[0106] Each sub-display area is used to display the visual signal sent by the peer device or the node device respectively. The window is a hardware window, which is used to display the video signal sent by the signal source device; before the user performs the actual interactive operation, the software side of the host computer first needs to pre-configure at least one window that has been opened in the virtual screen group of the software interface . The preconfiguration method is the same ...

Abstract

The invention provides a signal display control method, a previewing method, a previewing device and a display control system, which relate to the technical field of software control, and comprise thefollowing steps: receiving configuration information, and switching a display mode of a window to a display mode comprising at least two independent sub-display areas according to the configuration information; Receiving an external interaction action instruction; Judging whether the interaction position of the external interaction action instruction is a sub-display area or not, and judging whether a control object of the external interaction action instruction is a signal source control or not; If yes, generating a control instruction; The control unit is used for sending a control instruction to the visual signal service processing node; And receiving a return visual signal sent by the control unit, and pushing the return visual signal to the sub-display area according to a preview display strategy of the visual signal. According to the embodiment of the invention, the steps can be simplified, the configuration is refined and the overall efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of software control, in particular to a signal display control method, a preview method, a device and a display control system. Background technique [0002] In the existing signal display control method and preview method, when it is necessary to preview the images of multiple signal sources at the same time, multiple windows will be opened in advance in the control software, and the windows will be configured to determine the display resolution and display position of each window , associate each window with a visual signal, and establish a mapping between each window and the signal source device. From the perspective of the use of steps, this is cumbersome; the configuration is not refined enough, and the overall efficiency is low. [0003] For the above-mentioned problems in the signal display control method in the prior art that the steps are cumbersome, the configuration is not refined enough, and the ...
