Within a single NTB environment it is only possible to output one display.
This output can be distributed onto multiple screens with relative ease.
 
In a single location these screens can be upto 150m apart...
 
In order to display different content on multiple screens, one Net-Top-Box is required per ONELAN NTB output.
All content can be scheduled to cycle through content or change completely on upto a 7 day running routine.
 
For a multi-site system a single 'Publishing' NTB can share any content on a scheduled update routine.

Being internet based there is little limit to distance between physical locations. Nationally or worldwide!
