Problems solved by technology

[0003] like figure 1 As shown, a window (shown by the thick black line) spans three devices (device 1, device 2, and device 3), and is scheduled and displayed by three different handles (handle 1, handle 2, and handle 3). The handle numbers applied for are different, and one window cannot be operated at the same time; at the same time, since the management of one window requires different handle numbers, it is inconvenient for the control terminal to manage the windows. If multiple windows are used, the management burden of the control terminal will be increased

Embodiment Construction

[0015] In practical applications, the control terminal manages the handles of multiple windows, the specific process refers to figure 2 , including the steps:

[0016] 201. Application handle number;

[0017] The control end applies for the window handle number corresponding to each window.

[0018] 202. Issue a window opening command;

[0019] The control terminal broadcasts the window opening command to each device, and the window opening command includes: device identification code, window attribute, window handle number, and the corresponding relationship between the window and the device.

[0020] 203. Receive a window opening command;

[0021] Each device receives the window opening command and saves the window handle number.

[0022] 204. Find the window handle number that needs to be operated;

[0023] Each device returns a window opening response message to the control terminal, and if successful, the control terminal searches for the window handle number to be ...

Abstract

The invention relates to the field of video montage, and in particular relates to a multiwindow montage display method. A control terminal uniformly applies for a window handle number, and the handle number is issued to each device by virtue of a windowing command; each device saves the window handle number; and when the window operation is required, the control terminal finds the handle number requiring the window operation and informs each device by virtue of a window operating command. The control terminal uniformly applies for the handle number, thus the problems that the window display consistency is poor in the traditional method and the management efficiency is low are solved.

Description

technical field [0001] The invention relates to the field of video splicing, in particular to a multi-window splicing display method. Background technique [0002] A multi-device cascade processor needs to manage multiple video windows, and each window has different properties, and must have different handles to manage these windows. In the prior art, the splicing and display method of each window is as follows: the control terminal issues a window opening command, and each device applies for the handle number of the control window after receiving the command; each device cannot obtain the handle number of the other device, and the device The handle numbers applied for between may be different. Therefore, the control terminal must record these different handle numbers and unify them on the only window. The control terminal first searches for the handle number related to the window operation command, and then sends the handle number to the related devices respectively. [...
