Video switch control method and system thereof

Abstract

The invention provides a video switch method which comprises the following steps of: a validation step comprising checking whether a login account is valid or not; a reading step comprising sending a monitoring point list to a client when the login account is valid; an analysis step comprising analyzing a play mode of a monitor video of each monitoring point in the monitoring point list set by the client; a splitting step comprising controlling each agent computer to split screens of corresponding connected displayers; a playing step comprising controlling each agent computer to acquire first batch of monitoring videos from a digital video storage device, decoding the monitoring videos and playing the videos at a corresponding picture of a corresponding displayer; and a switching step comprising controlling the agent computers to decode a next monitoring video and play the video at an original picture of the original displayer. By using the method and the system, the agent computers are controlled to switch the monitoring videos without using expensive matrix equipment, and management is convenient.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video switching control method and system. Background technique [0002] In the video surveillance system, video walls are often used to play surveillance videos from various surveillance points. However, the display of the mosaic video wall is limited, and users generally hope to use a small enough display to realize multi-point monitoring, so the monitoring video of multiple monitoring points needs to be switched on one display. [0003] To switch the monitoring video played by each monitor on the TV wall, the traditional method is to use matrix equipment, including matrix host and master keyboard. However, the use of matrix equipment has the following problems: (1) The hardware cost of matrix equipment is high, and the number of surveillance videos played is exponentially related to the cost of matrix equipment; (2) The encoding specifications of matrix equipment are general...

AI Technical Summary

Problems solved by technology

However, the use of matrix equipment has the following problems: (1) The hardware cost of matrix equipment is high, and the number of surveillance videos played is exponentially related to the cost of matrix equipment; (2) The encoding specifications of matrix equipment are generally bound to manufacturers, and a complete set Use the equipment manufactured by this manufacturer; (3) The number of channels of the matrix equipment after leaving the factory is fixed. If you need to increase the number of channels, you need to install the manufacturer's decoder card

[0004] Now some manufacturers use a single computer to connect the display instead of the matrix device to control video switching, but as many displays as there are in the TV wall, it is necessary to control the video switching of the display on as many computers, which is inconvenient for users to manage.
