Digital signage is an emerging new communica tion technology. It is expected to play an important role in today’s dynamic world as digital signage displays timely information, while reducing the environmental costs associ ated with traditional printed signage. The main focus of this thesis is the design, impl ementation, and evaluation of a digital signage system based on a PC to display web contents (or other dynamic information) on digital displays located at one or more locations. The system will display information based upon a “playlist” that can be dynamically updated. It avoids the single poin t of failure of a television (be it analog or IPTV) based system, since each display has an attached pr ocessor and local storage containing both the information to be displayed and the local playli st of what is to be displayed. Additionally, the design allows content to be customized to specific local viewers, i.e., the information displayed can be adapted to th e user or users currently in front of the display. The granularity of the schedule (i.e ., playlist) is much shorter th an in existing digital signage systems – leading to a more visually dynamic experience for viewers. On the basis of our evaluation, we strongly believe that this approach to digital signage will displace existing signage systems.
