[0048] The LED display cabinet controller 20 includes a cabinet transmission unit 21, an image magnification unit 22 and a display driving unit 23. The cabinet transmission unit 21 is connected to the controller transmission unit 15 and the image magnification unit 22 respectively, and the image magnification unit 22 is connected to the display driving unit 23.

[0049] It should be noted that the LED display screen video processing method provided in the embodiment of the present application can also be applied to other suitable application scenarios. In the actual application process, more LED display box controllers and LED display screen controllers can also be included.

[0050] like Figure 2 As shown, the embodiment of the present application provides a method for processing video on an LED display screen, the method comprising:

[0051] Step 210, obtaining video image data.

[0052] The video image data is data input from an external video interface. The video image data is first acquired and then converted into internal video image data.

[0053] Step 220: Process the video image data to obtain reduced video image data.

[0054] In the embodiment of the present application, processing the video image data includes cutting and reducing the video image data. By cutting and reducing the video image data, the reduced video image data is obtained.

[0055] In some embodiments, as a specific implementation of step 220, such as Figure 3 As shown, the method includes:

[0056] Step 310: crop the video image data to obtain cropped video image data.

[0057] The video image data is cropped according to actual needs, and redundant parts are removed to obtain cropped video image data.

[0058] Step 320: Obtain a component of video image resolution in the cropped video image data.

[0059] In the embodiment of the present application, the components of the video image resolution include a vertical component and a horizontal component. Specifically, after the cropped video image data is obtained, the vertical component and the horizontal component of the video image resolution need to be obtained from the cropped video image data.

[0060] Step 330: When the component of the video image resolution is greater than the component of the LED display screen resolution, the cropped video image data is reduced to obtain reduced video image data.

[0061] When the component of the acquired video image resolution is greater than the component of the LED display screen resolution, the cropped video image data is reduced to obtain reduced video image data. Specifically, when the vertical component of the video image resolution is greater than the vertical component of the LED display screen resolution, the cropped video image data is reduced in the vertical direction to obtain reduced video image data; when the horizontal component of the video image resolution is greater than the horizontal component of the LED display screen resolution, the cropped video image data is reduced in the horizontal direction to obtain reduced video image data. By reducing the cropped video image data vertically or horizontally, the vertical and horizontal resolutions of the video image resolution are both less than or equal to the resolution of the LED display screen.

[0062] Step 230: Distribute the reduced video image data.

[0063] When the reduced video image data is obtained, the reduced video image data is distributed. Specifically, the reduced video image data is segmented according to the preset link or the display position of the LED display box; and the reduced video image data is sent to the corresponding LED display box.

[0064] Step 240: enlarge the reduced video image data.

[0065] After receiving the distributed reduced video image data, the reduced video image data is enlarged.

[0066] In some embodiments, as a specific implementation of step 240, Figure 4 As shown, the method includes:

[0067] Step 410: Obtain the component of the video image resolution in the reduced video image data.

[0068] In the embodiment of the present application, the components of the video image resolution include a vertical component and a horizontal component. Specifically, after the reduced video image data is acquired, the vertical component and the horizontal component of the video image resolution need to be acquired from the reduced video image data.

[0069] Step 420: When the component of the video image resolution is smaller than the component of the LED cabinet resolution, the reduced video image data is enlarged to obtain target video image data.

[0070] When the component of the video image resolution is smaller than the component of the LED cabinet resolution, the reduced video image data is enlarged to obtain the target video image data. Specifically, when the vertical component of the video image resolution is smaller than the vertical component of the LED cabinet resolution, the reduced video image data is enlarged in the vertical direction to obtain the target video image data; when the horizontal component of the video image resolution is smaller than the horizontal component of the LED cabinet resolution, the reduced video image data is enlarged in the horizontal direction to obtain the target video image data. By enlarging the reduced video image data vertically or horizontally, the vertical and horizontal resolutions of the video image resolution are equal to the resolution of the LED cabinet.

[0071] In some other embodiments, after obtaining the target video image data, the target video image data is converted into a driving signal required by the LED light board.

[0072] In the embodiment of the present application, by reducing the size of the video image data before data transmission and enlarging the video image data after data transmission, the data transmission bandwidth required for enlarging the video image data is saved, thereby achieving an increase in the image frame rate while reducing the image resolution.

[0076] A distribution module 530, configured to distribute the reduced video image data;

[0077] The enlarging module 540 is used to enlarge the reduced video image data.

[0078] In an embodiment of the present application, video image data is acquired through an acquisition module, and then processed through a processing module to obtain reduced video image data, and then the reduced video image data is distributed through a distribution module, and finally the reduced video image data is enlarged through an enlargement module. By placing the reduction of the video image data before data transmission and the enlargement of the video image data after data transmission, the data transmission bandwidth required for enlarging the video image data is saved, thereby achieving an increase in the image frame rate while reducing the image resolution.
