Lasers can also be used as a light source for digital projection. While this is still under development, we’re likely to see it first in movie theaters. Lasers can not only produce a much brighter image—which can help overcome the dimness of 3D presentations—but also offer cost benefits to theater owners. Conventional xenon lamps are expensive to replace, and have a useful life of perhaps 1000 hours (some theaters try to stretch this as much as possible, often with negative effects on picture quality). A laser light source can stretch this by at least twenty-fold or even more. While replacement lasers will likely be significantly more expensive to early on, they’ll still be cheaper per hour of use. Another possible cost saving might come from using a centralized “light farm,” with the light from a single remotely located bank of lasers routed to multiple projectors via fiber optics.

The gear has been packed back up and the rooms cleared. The demo material has been tossed into suitcases, destined to end up in an obscure corner of each exhibitor's factory, the place where overplayed and now unloved recordings go to die. And copious notes have been made on what worked and what needs to be improved.

In recent years CEDIA has moved beyond traditional A/V gear and into peripheral products such as home automation, security, and home health assistance — areas a custom install company might find useful in expanding its services. But traditional audio and video are still CEDIA's core attractions, and in showcasing both current and new products it draws a huge contingent from the A/V press.
