Apple’s upcoming high-definition television is real, and it will reportedly feature an aluminum construction, Siri, FaceTime video calling and more. An anonymous source speaking with Cult of Mac claims to have seen a prototype of Apple’s upcoming “iTV” in action, and a number of details have been reinforced as a result. “It resembled an Apple monitor, only much larger,” the unnamed source told the site, referring to the aluminum LED Cinema Displays Apple currently sells alongside its Mac computers. Cult of Mac, which has revealed accurate details surrounding unannounced Apple products in the past, also reports that the HDTV will feature Siri, Apple’s sophisticated voice recognition software, and an iSight camera for FaceTime video calling. Many expect Apple to launch its debut television later this year, though a recent report suggests that it may not hit the market until 2014.
