Aspect Ratio Converter
DESCRIPTION
FEATURES
The ARC-3901 is a modular, high quality aspect ratio converter for the NEO modular range of
interface products. The ARC-3901 will convert any aspect ratio picture to any other aspect
ratio picture (including 4:3, 14:9, 16:9 and 21:9 with letterbox and pillar-box modes).
The ARC-3901 will perform picture aspect ratio conversion on a video signal either under
manual control, or automatically by decoding the embedded aspect ratio information (widescreen signaling or video index).
The ARC-3901 features card-edge control as well as control via Leitch's CCS control system.
The ARC-3901 is part of the NEO modular range of interface products and can be mounted in
the 1RU frame (FR-3901) or the 3RU frame (FR-3903).
