Emerging technology was also a theme at this CEDIA, even apart from the various 3D videoschemes. Another technical demonstration of interest came from Focus Enhancements, a semiconductor and OEM company who demonstrated a wireless system for multichannel with 24-bit/96kHz and 7.1-channel capability. The big issues here are, in addition to the traditional ones of noise and distortion, the necessity for short transit times (to keep up with the video) and the reduction of interchannel time differences into the nanosecond range. The setup was done with the cooperation of Aperion Loudspeakers who provided prototypes of self-powered speakers with wireless ability. In practical terms, this system virtually eliminates speaker setup errors by assigning speakers to channels and setting levels/distances automatically and more swiftly than anything else I have seen. The accompanying picture shows what looks like very standard speakers but they are, in fact wireless!
