Advanced projection for presentation
When Airbus staged a huge customer event in Hamburg, Germany it turned to French integrator LCD vision to handle its audiovisual needs. Laurent Puget, owner and founder of LCD Vision, explains how the solution, was implemented.
We have been working with Airbus for many years. For their symposiums, we are handling between four and eight events all around the world each year. In general, these events bring together between 300 and 600 attendees. LCD Vision is a small company but thanks to our audio and video equipment and our team’s skills, we can manage events for up to 1000 attendees without subcontractors.
This was the second time we were working with the team in charge of the new A350 XWB program. For this show, we managed the whole event: projection, filming, audio, structure and cabling.
For basic presentations, we usually use two or three screens and video-projectors, with simple switches between sources. For the event that was held in Hamburg, we wanted to create something more elaborated and dynamic. We had to do an IMAG (image magnification) and display two PIPs. The first PIP was for the presentation, and the second one was displaying each speaker live. The other key element was the ability to broadcast an HD movie during the presentation.
We used Christie Roadster S+16K video-projectors to project on a custom-built 8x4.5m screen. For the sound system, we used eight L-Acoustics MTD115 speakers and two SB118 subs.
Given the innovative dimension of this presentation, we chose to use Analog Way’s Di-VentiX II. It was the ideal solution to manage this event. We were projecting a live IMAG, a PIP for the PowerPoint presentation and another PIP for the speakers’ desk. They were shot with a Sony HVR-Z1E camera.
Thanks to a Sony J-30/SDI Betacam Player, an HD movie was also broadcast every time the public was entering the room, four times a day. The monitor feedbacks came through a Di-VentiX. On the monitors, we were not displaying the entire projection but only the power point presentation. This is why we had to split the sources. The first flow was sent through the Di-VentiX II for the IMAG and PIPs, and the other flow was sent through the Di-VentiX for the stage feedbacks. On stage, there were two 26" screens and a 20" screen in the speakers’ desk. Everything was wired in DVI. The connection between the Di-VentiX II and the projector was made via fibre optic."
There were many sources for this event. For the Di-VentiX II, we had four computers: a main PC in 4:3 for the presentation and a PC in 16:9 for live IMAG. We also had two other PCs for back-up. We worked closely with computer specialists at Airbus. Sometimes, they asked us to switch to the back-up PC to make changes on the main computer. This enabled us to make live modifications on the presentation, without the public even seeing it.
The camera was plugged in YUV and the digital Betacam player in SDI. The last day of the show, we had another source coming from the stage. It was a PC dedicated to the debriefing of the event.
We worked very closely with Airbus before the show. Their graphic design manager supplied us with a background including a PIP, used as the first page of each presentation. The PIP should blend in with the background. This was a technical challenge in terms of image geometry and for the setup of colorimetry, contrast and brightness between the PIP and the background but we achieved it thanks to the Di-VentiX II. The choice of this solution was approved by Airbus beforehand. A team from Airbus came to our showroom in order to test the solution we wanted to opt for. For the show, we had to make an 8x4.5m (26’ x 13’) projection, so we created a 4x2.25m (13’x 6.5’) projection in our showroom to have the same ratio. Following this test, Airbus approved the solution with the Di-VentiX II.
Since it was a new type of presentation, we strongly prepared the project. We only had to make small adjustments for the presentation on site.
I had already used the Di-VentiX II for another 600 attendees Airbus symposium and the show ran smoothly. For the show in Hamburg, we had to remove the two PIPs from the live IMAG and then display in full screen an image coming from the Betacam player. The operating mode to manage these steps is simplified: I make my layers and when the script gives me the "Go" signal, I push the "Take" button and that’s it. I don’t need to go through multiple operations. The other good point of the Di-VentiX II is the real Preview function it offers. This function allows us to have a safe presentation.
We have been congratulated for the event. Our customer was very satisfied, even impressed. For future events for Airbus, we want to keep on producing the same kind of presentation.
Our customers are asking for more and more elaborated presentations, with IMAG among other things; that is why we recently opted for Di-VentiX II.
