Digital Signage
 
Digital signage is a method of electronically displaying advertising or other information. Digital signage is also sometimes called dynamic signage or digital out of home, abbreviated as DOOH. Often times the content is displayed in places located remotely from the source of the information, such as in public or private places for informational or advertising purposes. The messages delivered can be displayed at specific times. Digital signage is used in retail stores, fast food restaurants, schools, libraries, office buildings, medical facilities, airports, train and bus stations, banks, auto dealerships and other venues.

There are several advantages for using digital signs instead of printed signs. Digital signs can be quickly updated anytime from a remote location, while printed signs require physical replacement and require someone to travel to each sign location. Digital signs are environmentally friendly because they do not create any material waste such as paint or paper. Digital signs can be animated and can deliver multimedia content such as sound and visual content. The data on the screen can be updated in real time by means of an Internet or VPN intranet network connection. The information is often times compressed to minimize the amount of data required to send over a network. If an extra-large display is desired, the decode and display system may include multiple tiled screens. In this case intelligent decoder hardware is required for stitching together the large image across multiple displays.
