Video Walls

Various displays are in use in the Council Chambers system with varying native resolutions. The AMX matrix switcher has integrated output scaling on every output to deliver the native resolution of each display while maintaining source aspect ratio to prevent stretching and distortion of content. The existing two projectors have been replaced by 2 x 2 video walls, to display content to the audience. Each Video Wall independently displays any source of content available in the main switching system. All source content, regardless of aspect ratio will be scaled to create the largest yet undistorted image possible.

Council Dais

Every Council Dais position, Dais left wing and right wing (total quantity 9, 2, and 1) has a dedicated 22” monitor for viewing source content, all displays are independently routable and locally controlled via a button panel. If the user wishes to mirror the projector content locally, or route an additional source (limited by number of buttons on the keypad), a simple button press displays the desired content.

There are two separate council staff seating areas to either side of the council dais. Two 22” LED monitors were supplied and  share a single distributed video source, which may be routed by and control touch screen. Any source content may be viewed on these monitors. Three additional channels of duplicated video have been made available for added monitors through the 1×4 HDMI distribution amplifier.

Lobby Digital Signage

The lobby has three display areas that are connected to the switching system and display any source content. The two displays have been replaced with Samsung 48” signage displays with the existing mounting bracket reused. A third area has no display, but provides an “active video port” for personnel to connect a mobile display using a supplied AMX or compatible video receiver.

Broadcast System

Two HDSDI outputs have been provided as display outputs to the owner in the required broadcast standard resolution at which option will be connected to owner maintained fiber-optic transmitters.
