List updating method used for video-frequency display of multiple network cameras

Abstract

The invention discloses a list updating method for video-frequency display of multiple network cameras, comprising the following steps: forming a central list according to the device information of the network cameras, wherein, the central list and the network camera device are in one-to-one correspondence; generating an on-line list and an off-line list according to the on-line state of the network camera in the central list; displaying the network camera video to the corresponding position in the on-line list according to the user requirements, wherein, the on-line list and a video display child window are in one-to-one correspondence; updating a video display interface in the same split screen mode by respectively adopting a circular or manual manner; dynamically updating the video display interface through switching screens in different split screen modes; realizing connection and communication between each process through an interface mode; and the position of the network camera and the video display position are in an one-to-one corresponding in a dynamic update mode. The method of the invention enables a network camera application system to be more flexible, opener and moremovable.

Description

technical field [0001] The invention belongs to the technical field of network communication, and relates to a method for updating a list used for video display of multiple network cameras. Background technique [0002] The traditional network camera application system is to bind the network camera device and the video display window one by one. The fixed network camera video can only display the fixed position of the video interface, and the access and exit video display interface of any network camera cannot be updated synchronously. , its flexibility is poor, and the network camera lacks openness and mobility in the process of video display. [0003] In practical applications, the number of network cameras is increasing, and the requirements for the flexibility of network cameras displayed on the video interface are also increasing. The application system of network cameras should have the characteristics of flexibility, openness and mobility. Contents of the invention ...
