Sony is launching a 4K Ultra High-Definition movie-streaming service next week but it's not cheap.
4K is a relatively new picture technology used by TV manufacturers that quadruples the number of pixels found in a full-HD picture, with the aim of giving a clearer image on screen.
The service, called Ultra, will debut on April 4 only on Sony 4K Ultra HD TVs that have Android TV, Google's answer to Apple TV, on them.
Sony said that each movie will cost $30 in 4K with high dynamic range (HDR). Images shot in HDR essentially make the contrast between light and dark colors even more prominent so the white highlights are even brighter. The purpose is to make the image on screen look more realistic.
