During the event Spanish company SAC Audiovisuales was responsible for the central HD projection covering an area of 20 x 6m, for which it used two Christie Roadster S+20K projectors.
The meeting was held in Hall 2 at the Seville Conference and Exhibition Centre, comprising an area of 7,200 m2. SAC Audiovisuales was commissioned with producing and preparing the whole event, including projection, lighting, audio, translation, video, CCTV, IT equipment, AV design.
Gonzalo Palacio, manager and partner of SAC Audiovisuales says, "Very frequently, and due to the restricted budgets of some countries, the audiovisuals at previous sessions left a lot to be desired, which is why many people had a very simple idea about what an AV production could offer. Most of the previous sites for Unesco meetings did not have a venue with the features of the exhibition centre in Seville. In collaboration with the Seville Congress and Exhibition Centre, SAC Audiovisuales offered a new perspective in this regard, a different concept of audiovisual projection that had not been seen before in Unesco meetings. And I would venture to say that most of the people attending the event were extremely pleased and impressed with the result."
The mission of the Christie Roadster S+20K projectors (SXGA+, of 20,000 lumens, with 3-chip DLP technology and xenon lamp) was to provide a High Definition central projection on a 20 x 6m screen, showing the decisions and discussions taking place in the plenary session. The two Christie projectors were mounted on a structure hanging from the hall's ceiling at 20 metres high, and were located at a distance of 25 metres from the projection screen and 10 metres apart.
The two projectors were prepared to output images with an aspect ratio of 16:9. Thanks to the edge blending functionality two screens of 12 x 6.75 metres were joined in a gigantic screen. A video processor was used to generate the multimedia content for the presentations by means of the edge blending feature, as the images projected on the screen came from six different sources and were projected alternatively at different times. SDI signals came from the CCTV whilst the DVI signals were output from several PCs containing the conclusions and presentations in the two official languages of the Unesco (English and French). Also as part of the production of this event an iMac was used to create HD backdrops covering the whole 20 x 6m projection area.
According to Palacio, the audiovisuals were a resounding success. "The excellent response to the production of this event has meant a turning point for our company. I would say that the two Roadster S+20K systems are the crème de la crème in projectors, both for their excellent quality and brightness."
