Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0052] First, for ease of understanding, the application scenarios of the embodiments of the present invention are firstly introduced. Usually, in a video surveillance system, it may include multiple cameras distributed in different locations and a video wall in the surveillance center. Each camera is responsible for shooting its own location, and transmits the video data obtained by shooting to the monitoring center through an encoding channel, wherein each camera usually uses an encoding ch...

Abstract

The invention discloses a method and a system for realizing a video matrix function. One decoder in a video matrix is a master decoder, while the other decoders are slave decoder, wherein the master decoder is used for maintaining decoding channel information of the master decoder and each slave decoder and each piece of encoding channel information at the front end. The method comprises the following steps of: detecting and receiving serial port data by using the master decoder; analyzing the serial port data and determining a control type; according to the serial port data, the decoding channel information of the master decoder and each slave decoder and each piece of encoding channel information at the front end, determining a control command and a control object; and transmitting the control command to the control object to realize the video matrix function corresponding to the control type. Through the method and the system, the centralized management and configuration of the decoders can be realized, so that the video matrix function can be realized by adopting a digital method and the engineering complexity can be reduced.

Description

technical field [0001] The invention relates to the field of video signal processing, in particular to a method and system for realizing the video matrix function. Background technique [0002] One of the most important functions of the video matrix is ​​to realize the switching output of the input video image. In other words, it is to switch the video image from any input channel to any output channel for display. Generally speaking, an M×N matrix means that it can support M image input and N image output at the same time, and usually M>N. Wherein, the input channel refers to the channel used by the camera to transmit the captured image data to the monitoring center, and the output channel refers to the channel used when the image data is output to the video wall for display. [0003] In addition, another important function of the video matrix is ​​to control the PTZ. The gimbal is a hardware device used to adjust the position of the camera. Usually, the camera is in...
