Abstract

The invention relates to a flexible windowing video stitching processor, an LED display system and a storage medium, in the video stitching processor, an output control unit determines a video source interception area according to a connection relationship between layer setting parameters and output ports; the input acquisition unit is used for receiving and acquiring externally input video source data; the transmission interception unit intercepts video source data of a corresponding area from the collected video source data according to the received video source interception area; and the image processing unit is used for processing the intercepted video source data according to a preset processing strategy, and transmitting the video source data to a splicing screen for display through a corresponding output port. In the transmission and processing process, only video source data of a local area is involved, the bandwidth requirement in the transmission process is greatly reduced, and the flexibility of the number of layers is improved; meanwhile, the distribution of the layers can be set at will, and the function of windowing the multiple layers at will can be achieved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a flexible window-opening video splicing processor, an LED display system and a storage medium. Background technique [0002] LED display has the advantages of bright colors, high brightness, long life, energy saving, etc., so it is widely used. In actual use, especially in scenarios where information is collected in command centers, monitoring centers, and dispatch centers, LED displays may receive image data from multiple video sources at the same time, and then stitch them together for display. This requires the use of a video splicing processor, which uses layers to correspond to the image data of different video sources, and multiple layers are stacked together to complete the splicing and display of multiple video sources. [0003] Existing video mosaic processors, when performing multi-layer image display, are limited by the transmission bandwidth of the processing link...
