Problems solved by technology

In this way, the display controller needs to detect the frame rate of the input video source when receiving the input video source, which consumes system resources, and the display controller must also know the frame rate of the current video frame of the input video source after receiving it. low processing efficiency
In addition, current display controllers can only display video and images with a single frame rate. When the input video source is a dynamic video source, such as an input video source whose frame rate changes in real time, it may cause flickering and blurred screens. , the image display effect is poor, making people dizzy

Abstract

The embodiment of the invention discloses a video processing method, device and system, a display controller, a display control system and a computer readable storage medium. The video processing method comprises the steps: receiving an input video source, wherein the input video source comprises a first blanking period and a first effective image area which is located after the first blanking period and corresponds to the first blanking period, the first blanking period comprises first frame frequency information, and the first effective image area comprises first effective image data; analyzing the input video source to obtain the first effective image data and the first frame frequency information; and packing the first frame frequency information and the first effective image data group into field packet data and outputting the field packet data. The embodiment of the invention can reduce the loss of system resources and improve the processing efficiency.

Description

technical field [0001] The present invention relates to the technical field of video processing and display, in particular to a video processing method, a video processing device, a display controller, a display control system and a computer-readable storage medium. Background technique [0002] With the rapid development of display technology, the application of display control system is becoming wider and wider. Generally, a display control system includes, for example, a display controller (or called a sending card) and a display control card (or called a receiving card). In the display control process of the input video source, the display controller usually obtains the effective image data in each frame of video by analyzing the input video source, and detects the time of the field synchronization signal of the input video source to obtain the effective image data of each frame of video. The display time of the image data further obtains the frequency (frame rate) of t...
