Embodiment Construction

[0025] In the embodiment of the present invention, by controlling the resolution of the video data to be synthesized and merging multiple video data into one video data, the code stream of one video data is used to transmit multiple video data, which is equivalent to reducing the occupied space of multiple video data. Bit rate, so multiple channels of high-definition video data can be transmitted.

[0026] see figure 1 , the main method flow of video processing in this embodiment is as follows:

[0027] Step 101: Obtain multiple channels of video data to be synthesized.

[0028] Step 102: For each channel of video data to be synthesized, determine whether the resolution exceeds the resolution threshold, and if so, adjust the resolution to be equal to or lower than the resolution threshold. If the resolution threshold is not exceeded, step 103 is performed on the video data to be synthesized.

[0029] Step 103: Combine multiple channels of video data to be synthesized into o...

Abstract

The invention discloses a video processing method, which is used for transmitting multi-channel video content. The method comprises the following steps: acquiring multi-channel video data to be synthesized; judging whether the resolution of the video data of each channel to be synthesized exceeds a resolution threshold; if so, adjusting the resolution to be equal to or lower than the resolution threshold; and merging the multi-channel video data to be synthesized into one-channel video data. The invention also discloses a device and a system for realizing the method.

Description

technical field [0001] The invention relates to communication, embedded and image fields, in particular to a video processing method, device and system. Background technique [0002] Remote monitoring is the image monitoring system with the most development potential at present. The functions realized by the remote image monitoring system are, first, to transmit the image of the remote camera to the monitoring center, and second, to send control commands such as rotating the pan / tilt, changing the preset position, zooming the lens, etc. from the monitoring center to the remote camera. There are also two types of implementation schemes for remote image monitoring systems. One is to transmit images and commands through public telecommunication lines, and the other is to transmit images and commands through multiple nodes in a computer network. In addition to wired transmission, it also includes wireless remote image transmission system. [0003] For digital monitoring of WAN...
