While Comcast and Verizon have been the most vocal about connecting the TV experience with tablet devices, AT&T announced a new technology today that shows the U-verse operator isn’t letting the TV/Tablet trend pass it by. According to reporting from Engadget, the new tech uses Wi-Fi to connect mobile devices to AT&T set-tops. It supports DLNA and adds in authentication, a TV interface, and application context. And in a twist, the operator is opening up the technology to let developers create their own U-verse applications. AT&T’s sample application, ComplemenTV, gives you remote DVR scheduling on the iPad, and program guide info with connections to Amazon and Home Shopping Network for product purchases. Now this is interactive TV.
