The current home entertainment quality is HD delivered by HDMI and this is a very nice quality image. We can provide this to auditoriums and halls with the cost effective HDBT extenders and the newer IP based extenders and Cat6 network cables. These signals are robust and can be sent significant distances with the right type of components. Full HD (1080 x 1920) equipment is not only common but is also cost effective. Some of the linking devices are now able to handle the UHD (2160 x 3840) which is 4 x the resolution of HD. At this stage this level of system is possible and some components are expensive but in time this too will change.
Cameras, computers, and other devices can be connected to the presentation system. Other rooms can be linked in to provide overflow capability or for Creche or Mothers rooms.
We can provide wall plates that accept both HDMI or VGA type outputs from computers and send that signal via HDBT to the switcher at the control point.
We can work with the system you may already have to upgrade it in stages if needed.
Displays can be projectors or larger flat screens types. Vision mixing or switching including matrix switchers can be part of the solution for a system.
