Description

Switching System for Emergency Information Display and Method of Controlling the Same The present invention relates to a switching system for displaying emergency information and a control method thereof, and more specifically, to a switching system and a control method thereof for transmitting emergency information in various video display devices that provide information for public interest purposes based on video. Currently, public institutions are installing various video display devices to provide information for public benefit purposes. For example, diverse display devices such as Variable Message Signs (VMS) displaying road traffic information, disaster electronic display boards indicating disaster situations, bus information terminals providing arrival information, and digital signage for promotion and guidance process and provide information based on video according to their respective purposes. Various video display devices based on such images can be classified according to the display area into LCDs that use the entire screen and electronic display boards that use only a portion of the screen as the display area. In the case of conventional technology, although information suitable for the installation purpose was provided, there were limitations in that it did not provide practical help to users due to the simple and limited level of information provided. Meanwhile, efforts are required to maximize the utilization of urgent information—such as disaster and calamity information associated with the climate crisis, missing children, information on finding the elderly with dementia, and information on wanted persons—by exposing it to video display devices for the public good, especially in times like these. In order to transmit such urgent information to a video display device, there is a problem in that it requires paying costs to the management company of the conventionally installed video display device and making physical changes, such as modifying or changing the program of the management and control device. Therefore, there is a need for research on a switching system for an emergency information display and a control method thereof that can effectively expose emergency information while minimizing physical changes to existing video display devices.
