One of the tech standouts at the Consumer Electronics Show (CES) that took place in January of 2016, was the introduction of HDR TV. While OLED, 4K, and Quantum Dot TV have already made their mark on the flat screen tech market, HDR TV is now about to come into its own. But while those technologies are about more pixels, HDR TV is more about the quality of the images, which are comprised of those pixels.
HDR stands for High Dynamic Range and it is responsible for making widely varying lights and darks look better on your screen. HDR used in still cameras combine multiple images that may have different exposures. However, HDR in video uses a wider color pallet with greater depth of range to create greater contrast between light and dark areas of a scene. The result is a more realistic image.
HDR TV also involves a technology called Electro-Optical Transfer Funtion (EOTF) which is the process by which an electronic value is assigned to the real world brightness of your TV. EOTF allows a TV to brighten or darken a scene according to the brightness value it receives from the broadcast or playback source. This can give content producers more control of how an image will appear on your screen.
To watch HDR you'll need an HDR TV and HDR encoded content. Currently all 4K Blu Ray discs come HDR 10 encoded. Dolby Vision and UHD premium discs are available as well.
