XL Video Supplies Projection System For QI

XL Video supplied a projection system for studio recordings of 'Series L' of the QI Ltd/TalkBack Television show, QI.

Originally created by John Lloyd, QI is a comedy quiz show hosted by Stephen Fry, featuring regular panelist Alan Davies, which is broadcast on BBC2 in the UK. The set includes two projection screens that are key to the quiz show, displaying clues and visual alerts throughout the game.

For the projection, XL Video Project Manager, Jeff Bailey, specified two of XL's Barco SLM R12+ projectors, each of which fed to a 13ft x 7.5ft screen. Bailey chose the R12+ projectors for their three-chip DLP colours and bright 12,000 lumen light output.

For screens, XL supplied Repro H screens. These were selected as they minimize the hot spot that the camera sees in the projected picture – particularly important when projection is used for broadcast media.

In order to further minimize 'hot-spotting', the projectors were mounted on 18 ft high towers and angled down at the screens. The images were then digitally adjusted in the projectors to correct geometric distortion.

The current season which is airing on BBC2, was recorded at The London Studios, with a total of 16 shows recorded during the six week run.
