Embodiment 1

[0056] see figure 1 , which is a method flow chart of a video wall video window subtitle display method disclosed in Embodiment 1 of the present application. The method includes the following steps:

[0057] Step 101: Obtain video window information from the current control server, the video window information at least includes: any apex coordinates (X1, Y1) of the window, window width W1 and height H1, and window signal source name;

[0058] In general, the whole process of displaying various video signals on the splicing wall in the splicing wall display system is as follows: a splicing wall control service center sends a window opening instruction and sends the video window of the video signal to be output Information, the so-called window opening is to open the video window; after receiving the window opening instruction and the video window information, the splicing wall processor processes the received video signal to be output, and displays the video at the position det...

Embodiment 2

[0071] In order to better explain the method of the present invention, a specific application scenario is used as an example to describe the following. The specific scenario is: there is a video information whose signal source is geographical location image information near the National Convention Center, but the video information does not There is no subtitle information, in order to make users know more clearly what the image information displayed on the video wall is, such as figure 2 The various steps in the subtitle display method for the video window of the mosaic wall are shown to display the subtitle information of the video while displaying the video image information. Specifically include the following steps:

[0072] Step 201: Obtain video window information from the current control server, the video window information at least includes: any apex coordinates (X1, Y1) of the window, window width W1 and height H1, and window signal source name;

[0073] In the video...

Embodiment 3

[0110] see Figure 4 , which is a device structure diagram of a video wall video window subtitle display device disclosed in Embodiment 3 of the present application, and the device includes: an acquisition module 301 , a determination module 302 , a generation module 303 and a display module 304 . The internal structure and connection relationship of the device will be further introduced below in conjunction with the working principle of the device.

[0111] Obtaining module 301, is used for obtaining video window information from current control server, and described video window information at least includes: any apex coordinate (X1, Y1) of window, window width W1 and height H1, window signal source name;

[0112] Determining module 302, for determining the window area as the first area according to any vertex coordinates and window width and height of the obtained video window;

[0113] A generation module 303, configured to generate a glyph window according to the acquire...

Abstract

An embodiment of the invention discloses a method and a device for displaying tiled wall video window subtitles. The method includes: acquiring video window information, which at least includes any one vertex coordinate (X1, Y1) of a window, window width W1, window height H1 and name of a window signal source, from a current control server; determining a window area as a first area according to the acquired any one vertex coordinate of the video window, and widow width and height; generating a character-shaped widow according to the acquired name of the window signal source; and displaying the character-shaped widow in the first area. According to the method and the device, during image displaying of a video signal source without subtitle information, subtitle information of the video signal source can be edited and displayed according to actual demand without modifying hardware device of video, cost is reduced, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of splicing walls, in particular to a method and device for displaying subtitles in a video window of a splicing wall. Background technique [0002] The splicing wall technology is a professional display technology. The current large-screen splicing wall video display technology is developing well and has been widely used. For the signal source with subtitle information, the video signal is processed directly, and the signal is displayed in the display window on the splicing wall. In practical applications, many signal sources do not have subtitle information. Subtitle information is text information describing the name of the signal source. Therefore, there is only image information in the display signal window on the splicing wall, but no subtitle information. Inconvenience has been caused. [0003] For this signal source without subtitle information, the following processing methods are currentl...
