Abstract

A video wall control system for controlling a video wall including a plurality of screens, the video wall control system including: at least one client module controlling the layout of the video wall; a central control module acquiring camera unique identification (UID) and a video stream from a monitoring system, storing the camera UID and the video stream, and controlling the layout of the video wall; a storage module storing the modified video wall layout; a gateway module receiving a layout modification event from the client module or the central control module and load the modified video wall layout from the storage module; and a decoding module loading the camera UID and the video stream from the central control module, receiving the modified video wall layout from the gateway module, and modifying the layout of the video wall based on the received modified video wall layout.

Claims

1. A video wall control system for controlling a video wall including a plurality of screens, the video wall control system comprising:

at least one client module configured to control a layout of the video wall;

a central control module configured to acquire camera unique identification (UID) and a video stream from a monitoring system, store the camera UID and the video stream, and control the layout of the video wall;

a storage module configured to, in response to the layout of the video wall being modified by the client module or the central control module, store the modified video wall layout;

a gateway module configured to receive a layout modification event indicating the modification of the layout of the video wall from the client module or the central control module and load the modified video wall layout from the storage module; and

a decoding module configured to load the camera UID and the video stream from the central control module, receive the modified video wall layout from the gateway module, and modify the layout of the video wall based on the received modified video wall layout.

2. The video wall control system of claim 1, wherein the layout of the video wall includes a monitor layout in which each of the screens displays an image separately, and a wall layout in which the screens display an image together as if they were a single screen.

3. A video wall control method, comprising:

in response to video control being initiated, loading camera UID and a video stream into a decoding module from a video streaming server of a central control module;

in response to a layout of a video wall being modified by a client module or the central control module, storing the modified video wall layout;

transmitting a layout modification event regarding the modified video wall layout from the client module or the central control module to a gateway module;

in response to receipt of the layout modification event, loading the modified video wall layout on the gateway module from the storage module; and

transmitting the loaded modified video wall layout from the gateway module to the decoding module.

4. The method of claim 3, wherein the layout of the video wall includes a monitor layout in which each of the screens displays an image separately, and a wall layout in which the screens display an image together as if they were a single screen.
