Anyone looking for a TV in the most current standards may come across several that indicate functions and technologies present in the device, but which can be difficult to understand. The term Dolby Vision, available on many televisions, is one of those. What does it mean and what does it bring improvements to the devices? Can it be used only on TVs or also on cell phones? We explain everything below: 76r40
What is Dolby Vision a70s
O Dolby Vision is the standard of Dolby Laboratories to the format HDR — High Dynamic Range, or high dynamic range, responsible for improving the amount of colors displayed. Debuting practically next to the HDR10, Dolby Vision makes use of a color depth of 12-bit RGB — 4.096 shades per color, totaling 68 billion colors — bringing greater quality and fidelity to the image reproduced in this format.
Unlike HDR10, which typically offers a brightness of 1.000 nits (“candela per square meter”, a unit of luminance that indicates the luminous intensity produced by a surface), the technology of Dolby guarantees up to 10.000 nits. In addition, for a device to be able to use the technology, it must a series of prerequisites and standards required by the dolby labs, making devices compatible with the technology display similar images to each other — something that doesn't happen with devices certified only for HDR10 or even HDR10+, which may have several differences in the same image.
The implementation of Dolby Vision in content is also different from HDR10. While HDR10 is what we call static, that is, it relies on metadata (data about other data, in short) of the fixed image color enhancement information — the image information does not vary depending on the content scenes — the Dolby Vision is dynamic, bringing metadata that allows frame-by-frame adjustment of the content, modifying the intensity of HDR elements as needed and according to the device's .
Content producers who want their productions to be shown as faithfully as possible, regardless of device, have Dolby Vision an ally. With metadata that adapts to different scenes and screens, the displayed content presents the closest possible similarity to the original version of the content, from information on when to increase a color or the contrast between colors according to the video cut in question.
Another important factor in these implementations of the Dolby Vision is that if the device is not compatible with 12-bit color depth, the technology will be underused, as it is necessary that all the tones brought by this configuration are available for the real quality of the technology to be demonstrated.
DolbyVisionIQ 2q6i57
A Dolby, durante a CES 2020, showed the next step of its HDR format, the DolbyVisionIQ. According to the company, this new version of the technology optimizes the Dolby Vision content displayed on your TV according to the lighting in your room. This result is achieved through the t use of the TV's lighting sensor and Dolby Vision's dynamic metadata, adjusting the image to the environment.
Although several manufacturers already use the TV's lighting sensor to adjust the image according to the ambient lighting, combining this technique with dynamic HDR, without leaving aside the metadata that tells the TV how to display the different images, is a novelty that so far only the DolbyVisionIQ demonstrate.

Although in recent times more devices compatible with the technology of Dolby are appearing on the market, it is still not as widespread as devices with HDR10. One of the main reasons for this is that Dolby charges royalties to make the technology available on television sets, cell phones, tablets and other gadgets. Content - be it movies, series or games - must also pay royalties to be compatible with the Dolby Vision.
Currently, companies like LG, TCL, Philips e Sony have TVs certified for the Dolby Vision, usually on range models from manufacturers. On Apple mobile phones, Dolby Vision is ed from the iPhone 8 — however only from the iPhone X, with OLED screen, it is possible to play the content in maximum quality. already the My 11 Ultra, it is also compatible with the DolbyVision.
A Samsung currently does not implement Dolby Vision on its devices, but rather another form of dynamic HDR, the HDR10 +. The technology also s dynamic metadata for image adjustment, but is not that expensive to implement as it is royalty-free.
