Video & Audio Delay System.

DelayLine is a simple and cost-effective video delay system. DelayLine can be used in many applications where a constantly rewriting video store is required. Example applications include storing video whilst a video recording or transmission system powers-up, synchronizing video and audio feeds, sports coaching and action replay of sports or CCTV events.

DelayLine video delay system operates by utilising large banks of memory to provide video delay with only a negligible loss in quality. Various DelayLine models are available offering delays from milliseconds to over 1 minute. For flexibility, the amount of delay is user adjustable in 1/16 steps. Dual channel high quality audio delay, synchronized with the video, is available as an option.

The video delay system consists of a small DC powered unit that is very simple to install and operate.
