Here's how the technology of Aereo works. An Aereo user logs into Aereo online, and selects a show they would like to watch. If the show is currently airing, a dime-sized antenna in Aereo's Chicago warehouse picks up the signal from over the air, and then streams that show to the customer at home. If the show hasn't aired yet, the customer can use Aereo like a DVR, and record the show with their little antenna to watch later. In essence, Aereo is a broadcast television antenna rented over the internet, with included storage.
