Digital signage is a specialized form of slivercasting in which video or multimedia content is displayed in public places for informational or advertising purposes. A digital sign usually consists of computer or playback device connected to a large, bright digital screen such as an LCD or plasma display.Digital signage is often used to present a custom-tailored content mix, including product promotions, timely news, and upcoming events. Screens can be mounted on walls, ceilings, shelving systems, or aisle endcaps, or integrated into freestanding displays and kiosks. Digital signage is used in department stores, schools, libraries, office buildings, medical facilities, airports, train and bus stations, banks, auto dealerships and other public venues.
Small Device for Big Digital Signage Screens: Intel Compute Stick
A new type of computing device, the Intel Compute Stick enables you to transform a display into a fully functional digital signage solution via the display’s HDMI port. Ready to go out-of-the-box, the Intel Compute Stick has a quad-core Intel Atom processor and offers the performance, quality, and value you expect from Intel. The system performs just like your other computers. You can even choose your operating system—either Windows 8.1* or Ubuntu. Simply plug it into any HDMI monitor, connect to the cloud for your data or access files locally, and you’ve got a simple digital sign or a POS display.
Raspberry PI Digital Signage
Raspberry Digital Signage is an operating system designed for digital signage installations on the Raspberry Pi, which can handle both web and multimedia content. It displays a full-screen view restricted to the web page or slideshow/video playlist specified. It is a hacker-proof secure operating systems for indoor and outdoor use.
Web view shows HTML pages from an Internet or local area network resource, it has three different possible sub-views: you can choose between Mozilla Firefox, Google Chromium or Midori experience. Media view can display both a slideshow of images and a video player of Internet or local network files (http:// and https://).
Internet of Things (IoT)
Simple IoT Technology for Smart Digital Signage Monitoring
Digital Signage will play a crucial role in the IoT, and even today we’ve seen some fantastic uses of digital signage interacting with physical objects and their data sources, for example content being activated by wind pressure changes on the Subway and the communication between mobile apps, Apple iBeacons and digital screens — and this is happening now!
The expectation of communication between devices and objects will rise as more and more products are developed to incorporate multiple devices. Advanced medical devices, factory automation sensors in industrial robotics, sensor motes for increased agricultural yield, automotive sensors and monitoring systems for sectors such as transportation, water distribution and electrical transmission.
