Central Presentations provide audio visual support at the OpenText conference
Central Presentations (CPL) were selected to provide widescreen support for Maxim AVR for their annual OpenText conference in April 2009.
The brief was to provide high quality High Definition (HD) graphics and cameras across a 30’x10’ screen. CPL was required to integrate a variety of data and video streams, including cameras, client presentation graphics, event branding, and most importantly XML driven flash data. The main objective was to combine all of the above media with no loss of quality.
Onsite management of client assets led to CPL bringing together a variety of flash and video content using Apple’s Keynote ’09 software to produce a breathtaking display. CPL were uniquely able to capture XML driven flash streams from the web, at 3240x1080 resolution, and integrate them within the presentations. The technical crew edited live streams and dynamically changed the flash content depending on the client’s wishes. The ability to merge web, XML, flash and HD widescreen technologies is unprecedented.
In addition to widescreen services CPL provided broadcast camera systems. This allowed the client to capture ISO records of the event for post show editing, as well as providing on screen Picture-in-Picture (PiPs) of speakers throughout the event. These feeds were also relayed to screens outside the main auditorium to provide additional capacity. As well as cameras, CPL supplied sound reinforcement and digital processing to the main auditorium.
CPL chose to use a dual head HD setup, in conjunction with a two-way customised widescreen rack. This rack allowed the latest soft edge blending at the maximum possible resolution of 3240x1080p. The distribution systems included in the rack allowed CPL to take any source and display it anywhere on the 30x10 canvas, as well as using the full resolution background for specialist content and data.
To drive the projection systems, CPL used a 4-way fibre-optic DVI link to ensure no loss in quality between control systems and projection. And backstage, the system was controlled using a 4 way multi-viewer system which allowed the operator to preview all sources, as well as see the blended output of the projectors, all on a single HD display.
