Abstract

The invention provides a video display controller, for example, including a multi-channel video input interface, a programmable logic device, a microcontroller, a supervisory / monitoring multiplex interface and a video processing chip; the programmable logic device is connected with the multi-channel video input interface, the microcontroller, the supervisory / monitoring multiplex interface and the video processing chip; and the programmable logic device selects a target video source from the at least one original input video source received from the programmable logic device and the processed video source output by the video processing chip under the control of the microcontroller and outputs the target video source to the supervisory / monitoring multiplex interface. Therefore, the video display controller has the advantages of simple operation, convenient use, and high cost performance.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a video display controller and a video display control method. Background technique [0002] In practical applications of LED display screens, it is often necessary to monitor the image displayed on the LED display screen to detect the image information and stability of the current input source, so the manufacturer needs to provide an output interface to output the image to the monitor. This monitors the image displayed by the LED video. In addition, some users need to preview the current input source, and when the video source is previewed to the required image content, and then project to the LED display screen for display, then the manufacturer also needs to provide an output interface to preview the current in real time Input source. The current market situation shows that LED video display controllers rarely provide video surveillance interfaces or video preview interf...
