New technologies are making waves at the 2008 CEDIA Expo.

The explosion in whole-home, centralized control has driven a lot of innovation in recent years. This trend will continue, largely driven by consumer interest in reducing carbon footprints.

“It's more about people's personas and politics than saving money, although that's certainly a factor,” Pedigo says. “Whether you agree with Al Gore or not, he sure has raised awareness of energy issues — and it's a growing force in the marketplace.”

One new technology is enmeshed network protocols. Driven by the need to have wireless systems in various spectrum areas communicate quickly, seamlessly, and reliably, the concept allows improved energy management and efficiency. This has been largely pursued by the ZigBee Alliance, a group of companies working together to create a global open standard. The group has already certified nearly two dozen ZigBee Smart Energy products using this protocol, and more are on the way.

Not everything will be wireless. Although it was considered less than optimal in the past, power-line-carrier technology has made great strides in the past year. Pedigo says a reinvigorated effort now enables data transfer over existing home infrastructure. This makes retrofitting new technology into older homes much less invasive and easier to implement.

Lighting is another area where change is ongoing. Compact fluorescent lighting (CFL) has taken off. Traditional incandescent sources are also becoming more efficient, especially when combined with dimmer systems — something that is difficult for CFL lights. Most efficient of all is LED lighting, although those systems share a certain harshness with their CFL brethren. Lighting manufacturers are working to develop warm-colored, dimmable, energy-efficient lighting systems.


When it comes to comprehensive control systems, it seems that Internet protocol (IP) has already won the war. “And it will get stronger,” Pedigo says. “If you don't know Internet protocol already, you'd better jump on the wagon now, because everything will continue to be increasingly IP-driven.”

One of the biggest advantages of IP control is that it can contribute directly to the integrator's bottom line. “Traditionally, integrators have worked on a break/fix business model. But with a properly integrated remote IP solution, 90 percent of customer problems can be address without a truck roll,” says Brian Post, CEO of Evanston, Ill.-based integrator LouisClark and its spinoff service provider, Atomoo.

Apple iPhone is another example. With Apple's release of its software development kit, a world of possibilities has been opened. “I was in the U.K. recently and saw a custom installer who literally controls everything within the home with an iPhone,” Pedigo says. “It was simple to use, very intuitive, and very robust.”

With the ability to receive and store HD content directly, media centers are being freed from the tyranny of the silver disc. So broadband delivery and IP control of the entire AV experience is now practical, limited only by available bandwidth.

Surround sound is also developing quickly. The most exciting development that Pedigo sees is digital signal processing (DSP) being applied to room acoustics. Instead of relying on parametric and traditional EQ, high-end DSP is becoming increasingly capable of doing room correction for loudspeakers on a software level. In fact, some manufacturers have already demonstrated wireless surround-sound systems with individually IP-addressable loudspeakers.


The most outrageous new technology may be immersive virtual-reality rooms — where multiple, edge-blended displays and powerful computing are used to create custom, changeable environments. While this sounds sci-fi, such rooms are already being designed and installed, notably by Rich Green — an independent contractor and chair of the CEDIA Technology Council.

The Technology Council will have a booth at CEDIA Expo, allowing integrators to explore the opportunities these new approaches enable. In addition, the council has launched a website for CEDIA members at

Scheduled prior to and after the convention, Rich Green and Michael Heiss will host free, 1-hour seminars addressing future technology. The pre-show seminar will cover things to look for at the show as well as predictions. The post-show seminar will include a show wrap-up and discussion.

“Long-term, the future is very bright in this industry,” Pedigo says, “and it's all driven by technology. The old attitude that technology is nice to have has been replaced. Today, we've reached the point where we consider technology as an integral part of our lives.”
