On televisions, this is achieved via a small set-top box -- a prototype of which approaches the size and noiselevel of a mini-fridge -- that plugs into the video source and the TV and converts the video in real-time with virtually no latency.
Besides being almost as thin as a credit card (not really), this award-winning ultracompact boasts a pretty impressive set of features, including a maximum ISO of 4000 (no word on noise at that level, however), 2.5-inch LCD, and Super Shake-Free image stabilization.
