Abstract
This invention provides a digital signage system including a display device and a host device. The host device includes a playing unit and a monitoring unit. The playing unit plays signage content on the display unit. The monitoring unit captures a first image displayed on the display device after the digital display system is powered on. After the display device experiences a specific event, the monitoring unit captures a second image displayed on the display device when the playing unit is playing. The monitoring unit compares the first image and the second image to determine whether the display device displays abnormally.
