This year’s April NAB2000 - that’s the National Association of Broadcasters - extravaganza in Las Vegas drew over 115,000 people to the halls of the Sands and Las Vegas Convention Centers. The ninfo picks a few of the highlights for your delectation?  One of the key themes to emerge from the conference was providing tools and applications that will serve many platforms, rather than just set-tops or the Web. Companies Vertigo and Peak Broadcasting have developed systems that will send data from a Web site to TV platforms and even to live television broadcast graphics. These tools can broadcast data collected on a Web site to control servers where a producer dynamically sends that data to a broadcaster where it can then instantaneously reflect people’s perspectives on regular TV - at a cost of just $5,000-10,000. Applications sure to develop are games, live sports data, news, and more.Other highlights from the exhibition floor included: the Jive multi-player BBS gaming app over NDS and OpenTV platforms amd MediaStorm?s multi-platform broadcast server. But the big news is Veil Interactive’s demo of their Veil 1 & 2 technologies. Veil 1 allows handheld thick, yet, light weight cards to receive a signal from the visible light during a broadcast which registers a tone and LED light. This technology has been in place with the company (and others) for many years; however, but Veil is now building partnerships and demonstrating possibilities starting with projects with 2 Fortune 500 companies. At the show, the company demoed how a Palm unit could be used as an interface and the questions for Chris Tarrant?s ?Who Wants to Be a Millionaire? TV show, commercials, sports data, and so on. Delay was negligible. Veil’s technologies obviously open the way for a host of interactive TV offerings at a relatively low cost. As one company representative comment, the limits are now really in the imagination of the developers.
