Embodiment 1

[0051] refer to figure 1 , showing a flow chart of the steps of Embodiment 1 of a multi-channel video display method of the present invention, which may specifically include:

[0052] Step 101, obtain a line of pre-read video source data;

[0053] Specifically, in this step, the video display device, specifically the display engine in the video display settings, obtains one line of pre-read video data from the video data buffer area; the one line of pre-read video data mentioned here It can be used to refresh a line of pictures on the display screen (specifically, the display screen of the monitor).

[0054] Step 102, after the mosaic processing is performed on the one row of video source data, the video source data after the mosaic processing is output to the target row position of the display screen;

[0055] Specifically, the video display device performs mosaic processing on the video source data, so that the video data matches the display area on the display screen and ...

Embodiment 2

[0058] refer to figure 2 , showing a flow chart of steps of an embodiment of a multi-channel video display method of the present invention, which may specifically include:

[0059] Step 201, successively read the video data on the multiple channels corresponding to one line of pre-read video source data;

[0060] Specifically, before step 201, the following steps are further included:

[0061] One or more lines of video source data are read in advance and stored in the video buffer area; wherein, each line of video source data is composed of video data on multiple channels. Specifically, the video buffer area may be a first-in, first-out (FIFO, First InputFirst Output) queue.

[0062] Specifically, the video data of multiple channels corresponding to one line of video source data is read in the following manner:

[0063] Read the configuration information of the updated video data on the corresponding channels from the video data registers corresponding to the multiple chann...

Abstract

The embodiment of the invention provides a multichannel video display method and device. The method comprises the following steps: acquiring a row of video source data read in advance; and performing mosaic processing on the row of video source data, and outputting the video source data subjected to the mosaic processing to a target row location of a display screen. Through the embodiment of the invention, display of multichannel video data is realized, and system bandwidths can be saved remarkably.

Description

technical field [0001] The invention relates to the technical field of electronic equipment control, in particular to a multi-channel video display method and device. Background technique [0002] With the development of video hardware equipment, the demand for video multi-channel technology is increasing, and the specific requirements are becoming more and more diverse. At present, the mainstream video multi-channel technologies in the market are as follows: [0003] 1) Each channel requires the same frame rate, so the puzzle must be completed through a special puzzle engine, and then unified to the display engine after the puzzle is completed. [0004] 2) Each channel can have a different frame rate. It is necessary to use the puzzle engine to puzzle the video data of each channel according to the fastest frame rate. During the puzzle process, for the channel with a slower frame rate, when the puzzle engine completes the puzzle once After stitching, for the next or even n...
