Overview
The Unison Mosaic Audio Visual Controller (AVC) is a companion to the Unison Mosaic MSCs. It allows the
same level of intuitive control for audio and video that the MSCs provide for lighting.
Like the MSC, it is a rugged solid-state device in a compact DIN-rail mounting enclosure. Video and audio con-
tent is stored on a memory card (2GB card provided as standard) with instant access (no “seek” time) to any clip
for playback. Video content is MPEG2 at full D1 resolution, that is DVD quality, and the aspect ratio can be either
4:3 or 16:9 anamorphic. Video output is selectable as composite, S-Video or component signals along with stereo
balanced analogue.
However, the fundamental difference between the AVC and other video playback devices is that the AVC incor-
porates two separate players and a vision mixer. This means that it can respond immediately to external triggers
and perform graceful transitions (dissolves, wipes, etc.) between two clips. This is a huge advantage for any sort
of interactive or themed application and allows the compact AVC to replace multiple discrete items of larger AV
equipment.
The AVC incorporates a live input so that a camera or other video feed can be mixed with its internal playback.
There is also an internal effects unit supporting picture-in-picture and luma-key effects. Finally a separate overlay
(downstream key) is supported which could either be a customer logo or text, including scrolling text from an
external source.
