Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Before describing the present invention, the abbreviations of related nouns used are introduced:

[0028] Video preview window - VW;

[0029] Microsoft DirectShow technology architecture - DShow;

[0030] Video Mixing Render in DShow - VMR;

[0031] Filter component in DShow——Filter;

[0032] Filter connection collection-Graph in DShow;

Abstract

The invention relates to a video pre-monitoring technology, in particular to a self-adaptive multi-channel and multimode video pre-monitoring method used for hardware of a video server. The method comprises the following steps: after the input multi-channel video data is received, the input video data format is set, and the video re-sampling is performed; and then the video mixing is performed to the multi-channel video data, the mixed data is output by positioning, and a multi-channel video pre-monitoring window picture is formed by configuring the position of a pre-monitoring picture. The invention is suitable for (but not confined to) simultaneously monitoring the video data of all the channels under the multi-channel video data acquisition mode of the video server, the hardware self-adapting function of video pre-monitoring as well as the video mixing function of the multi-channel data is realized by the method, the display can be performed through various template forms, and the invention can be used for various devices such as analog television walls, material browsers, and the like by adjusting the data source or the video arrangement method.

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 preview mode of the current video server in the acquisition state is mostly the mode of outputting a single-channel video signal to the monitor by occupying one channel of the video IO card, or the mode of using the software monitoring window to monitor the single-channel video. In the state of simultaneous acquisition of multiple signals, it is not possible to monitor all input videos at the same time. Using the hardware channel of the board will be limited by the working mode of the board (for example, the video capture card does not support duplex mode), and will increase the system cost; while the current software-based video preview method of the PC monitor, if you want to realize multi-channel Video mixing (Mixing Blender) generally requires the graphics c...
