How does Digital Signage work?

A typical digital signage network is comprised of a centrally located management server and many networked display panels installed at various locations. A local media player, which is usually installed at or near the display panels, receives contents from the central management server and plays the contents locally for one or several display panels. For example, a corporation can deploy a digital signage network for corporate communications. One or many displays and media players can be installed in each division or building on the corporation's campus. The management server can be hosted centrally. Administrators of the content can centrally deliver weekly or even daily messages to some or all of the displays in real-time or based on predefined schedules, all from their desk top.
