Internet Initiative Japan (IIJ) and T-NET Japan are demonstrating a hybrid integration of emergency alerts for broadcasting and broadband smart TVs at this week's National Association of Broadcasters convention. A consortium of Korean broadcasters and manufacturers is also demonstrating UHD. In addition to the gorgeous video, the Korean UHD consortium has a very nice emergency alert demostration. Korea and Japan seem to be the leaders. The U.S. smart assistant companies (Amazon and Google) have very large booths on the NAB show floor, but their products don't have emergency alerts.
