Dolby has reviewed the technology Dolby Vision at a conference in Seoul. Dolby Vision is one of the formats with which it is possible to convey content in HDR (High Dynamic Range). Than HDR10, the format “rival” promoted by Alliance Ultra HD, Dolby Vision has some advantages. They are in fact used metadata (the information display and projectors use to manage peak brightness) dynamic instead of static. The difference is that dynamic metadata can also change frame by frame, allowing you to optimize the performance on the screen.

Dolby Vision also requires the payment of royalties and a hardware additional inside the device. The integrated chip is also required to manage Mapper Display inserted right in hardware (and this is one of the reasons why it is not possible to add support for Dolby Vision through a simple firmware update). This solution perfected by Dolby identifies the capacity of the TV or projector at the level of peak brightness, black level and volume of the color (that is the representation of the chromatic coordinates in the “size 3”, obtained by adding the brightness in hue and saturation) . In this way you can get a more accurate mapping of the contents which are then reproduced with the best performance guaranteed by the TV in use.

In Seoul Dolby announced that it had entered into a cooperation with five TV manufacturers to LG (with all the new OLED range, including the model 55B6V which we recently reviewed) and Vizio were added TCL Loewe (with bild7 ) and Skyworth (which controls Metz will then be verified support on new OLED Novum ). Soon Dolby Vision also coming on TV Changhong Funai and Hisense (probably in 2017).

as far as the contents are six Hollywood studios that actively support Dolby Vision for the home market. We speak specifically of Sony Pictures Warner Bros. Universal Paramount Lionsgate and MGM . Some movies are available streaming of four services online (including Netflix and Amazon video ), and others will come in 2017 also on Ultra HD Blu-ray. Among the technology partners we have been cited Nvidia, MediaTek, Sigma, Mstar and ARRI.
