Abstract

The invention relates to video preview technology, in particular to a hardware self-adaptive multi-channel multi-mode video preview method for a video server. After receiving the input multi-channel video data, the method sets the format of the input video data and performs video resampling; then performs video mixing on the multi-channel video data, and positions and outputs the mixed result data. By configuring the position of the preview screen, Form a multi-channel video preview window screen. The present invention is suitable for (but not limited to) the application of simultaneously monitoring the video data of each channel under the multi-channel video data acquisition mode of the video server, and realizes the hardware self-adaptive function of video preview and the video of multi-channel data through this method. Mixed functions, and can be displayed in a variety of template forms, by adjusting the data source or video arrangement, the present invention can be used in various applications such as analog video wall, material browser and so on.

Description

Technical field

[0001] The invention relates to video preview technology, in particular to a hardware self-adaptive multi-channel multi-mode video preview method for a video server. Background technique

[0002] The current pre-monitoring methods of the video server in the acquisition state are mostly the method of outputting a single-channel video signal to the monitor by occupying one channel of the video IO card, or the method of single-channel video monitoring using the software monitoring window. In the state where multiple signals are collected at the same time, it is not possible to monitor all input videos at the same time. Using the board hardware channel will be restricted by the working mode of the board (for example, the video capture card does not support the duplex mode), and increase the system cost; while the current video pre-monitoring mode that is software-based to the PC monitor, if multiple channels are required Video mixing (Mixing Blender) generally requir...
