Web-based video-on-demand services, like Netflix and Amazon, compress their video to avoid hogging bandwidth, and often the result is grainy or blippy images, even if they're high-def. XStream can deliver carbon copies of studio masters because it beams them via satellite. The company broadcasts over common low-power satellites, and a 2.5-foot dish on your roof grabs the signals. Then a server box in your living room uses specialized receiver chips to weed out interference and saves up to 160 films so they're waiting for you the next time you turn on the TV. By default, it keeps the most popular titles, but you can also tell it to record specific films or genres and store them on its up-to-four-terabyte drive.
