Video splicing and displaying method and displaying control equipment

Abstract

The invention discloses a video splicing and displaying method and displaying control equipment and is used for improving resolution of spliced video images. The video splicing and displaying method comprises the steps of collecting at least one way of video signal through utilization of at least one collection port on the displaying control equipment, and storing synchronization information contained in each way of video signal, wherein each collection port collects each way of video signal, and the synchronization information contained in each way of video signal is a count value of a framesynchronization Vsync signal in each way of video signal, and if the count values corresponding to any two frames of video signals are the same, the collection time of the any two frames of video signals is the same; and controlling the at least one way of video signal to be output to a displaying side for synchronous displaying, according to the synchronization information contained in each way of video signal.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to a video splicing display method and a display control device. Background technique [0002] The current display control device collects a complete video picture through one port, and then sends it to multiple output ports, and performs splicing and display after processing such as zooming through the multiple output ports. However, the single-port capture is finally output to multiple output ports, which reduces the resolution of the video image. [0003] Therefore, in order to obtain a higher resolution of the video picture finally output by the output port, it is necessary to collect a video picture with a higher resolution. However, due to the limitations of the hardware resources on the display and control device, such as the acquisition port and the hardware resources for processing the video such as zooming, the acquisition port cannot capture higher-resolut...

Problems solved by technology

However, due to the limitations of the hardware resources on the display and control device, such as the hardware resources of the acquisition port and the processing of video scaling, the acquisition port cannot capture higher-resolution video images at all.

As a result, the resolution of the video image finally output by the output port is still low, and the video image may be blurred.

[0004] It can be seen that the current video splicing display has a technical problem of low resolution of the spliced ​​video images
