Display-integrated Digital Signage
If displaying complex contents is not necessary, display-integrated content replay with SoC (System on Chip) system can be the right solution. This is both cost-effective and makes it easier to install the end point since it does not require a specific player. In this case, displays are directly connected to the IP network and register to the centre where they receive the scheduled content from. Since the content is uploaded to the display, a continuous replay can be ensured even in case of a network outage. The amount of simultaneously displayed information is limited compared to the external player solutions, typically a full-screen content or playlist can be displayed. Some manufacturers offer split-screen content display after purchasing a licence key but the number and nature of displayed zones are restricted.
Systems with external players
All features of Digital Signage systems can be exploited using external players. In this case, players are placed behind the displays to which they are typically connected to with an HDMI cable. Scheduling, uploading and displaying of the content is similar to the integrated player systems but there is a significant difference in regards to the usable content and the simultaneously displayable layers. Almost any screen division can be applied and the list of supported file types is also extended. Supporting dynamic content display from a data file (RSS feed), commonly used by Digital Signage systems, is typically the ability of external players.
Dynamic data and interactivity
In many cases with Digital Signage systems, continuously and automatically updating information also needs to be displayed besides pre-uploaded content. To achieve this, objects that can read from data files (xml, csv, txt) in specified intervals can be created with the content editor application. The content can also be changed externally, like a press of a button on a website or mobile application, perhaps as a result of an external trigger. This way, Digital Signage systems can be transformed into interactive surfaces or menu systems where the content can also be changed by the ones standing in front of the display. Interactivity is also increased by the spreading of touch-sensitive screens or screens that are made so by an external frame.
