Barco's LiDo is a proprietary, state-of-the-art video line doubler (31.25 kHz), which may be incorporated into any new Barco 701, 701s, 708, 808s, 1208s, 1209s, 1609s series projector and into Barco's RCVDS 05 switcher.

　　It greatly reduces visible line structure inherent in video images and produces a smoother, more pleasing video image.

　　Three circuits

　　BARCO's LiDo works in unison with the Video Decoder of the projector, which incorporates a three-line adaptive Comb filter and special enhancement circuit.

　　The three-line adaptive Comb filter improves coulour transitions and reduces noise in the video signal.

　　The enhancement circuit integrated in the decoder provides sharper images with clearer outlines.

　　The LiDo line doubling circuit reduces visble line structure by doubling the number of lines of the video image through BARCO's digital Smart Motion Detection Filtering. An integrated, specially designed Phase Locked Loop (PLL) circuit stabilises the image quality, especially when using poor quality video tapes.

　　These three circuits work in unison to produce a smoother, yet sharper image which is significantly more appealing when watching video images.
