HDR<\/b>, or High Dynamic Range, is a video technology that improves image quality by providing higher brightness, contrast, and a wider color gamut.\u00a0To date, it is represented by three main formats –\u00a0\u00a0HDR10<\/b>\u00a0,\u00a0\u00a0HDR10 +\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision<\/b>\u00a0.\u00a0Accordingly, when choosing a TV, buyers are wondering which one is better, because different models support different\u00a0\u00a0HDR<\/b>\u00a0technologies .<\/p>\n
In this article we will consider their features, advantages and disadvantages.\u00a0And based on the results of the analysis, we will try to answer the question in the title.<\/p>\n
The key determinants of\u00a0\u00a0HDR\u00a0<\/b>\u00a0quality are color depth, brightness, tone mapping, and metadata.\u00a0Of the three formats under consideration,\u00a0\u00a0HDR10\u00a0<\/b>\u00a0is the simplest and most common.\u00a0As for the more advanced\u00a0\u00a0HDR10+\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision<\/b>\u00a0, most\u00a0\u00a0HDR<\/b>\u00a0capable TVs only offer one of these.\u00a0Although there are universal copies on the market that support all three formats.<\/p>\n
As you can see, Dolby Vision<\/b>\u00a0is ahead of its competitors in terms of the average score\u00a0\u00a0, and the winner seems to be clear.\u00a0But not everything is so clear.<\/p>\n Conclusion.\u00a0Technically\u00a0\u00a0<\/b>, HDR10\u00a0\u00a0<\/b>is an outsider of our trinity, so further analysis will mainly come down to comparing HDR10 + and Dolby Vision.<\/b><\/p>\n As far as our formats go, 10-bit depth is the max for\u00a0\u00a0HDR10<\/b>\u00a0.\u00a0And\u00a0\u00a0HDR10+\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision\u00a0<\/b>\u00a0can technically overcome it, although such content is quite rare and is found only on\u00a0\u00a0UHD Dolby Vision Blu-ray discs<\/b>\u00a0.<\/p>\n Conclusion.\u00a0Despite technical capabilities, real content in HDR10 + and Dolby Vision is created within 10-bit color depth, and for streaming applications this mark is completely insurmountable.\u00a0Therefore, in terms of this parameter, there is no difference between HDR10 + and Dolby Vision for the consumer.<\/b><\/p>\n This parameter is key for high-quality\u00a0\u00a0HDR\u00a0<\/b>\u00a0transmission and there is a direct relationship here.\u00a0If the content is recorded at\u00a0\u00a01000 nits<\/b>\u00a0, then the TV must also support\u00a01000 nits<\/b>\u00a0for its high-quality transmission.<\/p>\n Most\u00a0\u00a0HDR\u00a0<\/b>\u00a0content today is created around\u00a01000 nits<\/b>\u00a0of peak brightness , but\u00a0\u00a0HDR10\u00a0<\/b>\u00a0clearly outperforms its two rivals in terms of its minimum value, which, of course, affects image quality.\u00a0Technically, the whole trinity far exceeds the capabilities of today’s TVs.<\/p>\n Conclusion. There is no difference between HDR10+ and Dolby Vision for the consumer in terms of peak brightness, as both formats operate in the same practical ranges.<\/b><\/p>\n Metadata is a technical instruction that describes content parameters.\u00a0It is written directly into the video signal and dictates to the TV how best to display it.<\/p>\n In this regard\u00a0\u00a0, HDR10+\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision\u00a0<\/b>\u00a0are more advanced formats that use dynamic metadata.\u00a0That is, the instruction that accompanies the corresponding content transmits to the TV the parameters of its best display for each scene separately, up to frame-by-frame optimization!\u00a0Of course, such an individual approach gives a better result.<\/p>\n However, there are pitfalls here as well.\u00a0Some TVs ignore the metadata and use their own image processing algorithms instead.\u00a0In this case, it does not matter what\u00a0\u00a0HDR\u00a0<\/b>\u00a0format you are viewing and you can only rely on the quality of the TV.<\/p>\n Conclusion.\u00a0HDR10+ and Dolby Vision are more advanced formats as they adapt picture parameters to each individual scene.\u00a0<\/b><\/p>\n As we have shown above with the example of color depth, content editing options can exceed the capabilities of the TV.\u00a0Consider an example.\u00a0When recording a scene, red is used in such a bright hue that the TV cannot display.\u00a0Further, 2 scenarios are possible.\u00a0In the first case, the so-called clipping occurs, when the brightness of the scene becomes so high that you cannot see its details.\u00a0As you may have guessed, this phenomenon is typical for not the highest quality screens.<\/p>\n In the second case, the TV performs color conversion, trying to adapt to the content using the range available in its arsenal.\u00a0That is, it “compresses” the range of colors of the video signal to its own capabilities, hence the term “tone mapping”.\u00a0As a result, the transfer of the scene close to the original is achieved without loss of detail.<\/p>\n The static nature of the\u00a0\u00a0HDR10\u00a0<\/b>\u00a0format tells us that the tone mapping in this format stays the same for the whole of a certain movie, which leads to not the best result.<\/p>\n The dynamic\u00a0\u00a0HDR10+\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision\u00a0<\/b>\u00a0formats can apply tone mapping for each scene individually, achieving a higher quality image.<\/p>\n Conclusion.\u00a0HDR10+ and Dolby Vision dynamic tone mapping result in better image reproduction.<\/b><\/p>\n A number of manufacturers are leaning towards universality, providing support for both of these formats on their TVs.\u00a0These are, for example,\u00a0\u00a0Hisense<\/b>\u00a0,\u00a0TCL<\/b>\u00a0,\u00a0Panasonic<\/b>\u00a0,\u00a0\u00a0Philips<\/b>\u00a0.<\/p>\n From a technical point of view, the two progressive formats HDR10+\u00a0<\/b>\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0<\/b>Vision\u00a0<\/b>\u00a0do not reveal a clear winner between themselves, as our analysis shows\u00a0\u00a0, since they use dynamic metadata and achieve comparable high quality.\u00a0However,\u00a0\u00a0Dolby Vision<\/b>\u00a0content is much more common than\u00a0\u00a0HDR10+<\/b>\u00a0content .\u00a0The most popular\u00a0\u00a0HDR\u00a0<\/b>\u00a0format among both TV manufacturers and content producers is the simplified\u00a0HDR10<\/b>\u00a0.<\/p>\n HDR, or High Dynamic Range, is a video technology that improves image quality by providing higher brightness, contrast, and a wider color gamut.\u00a0To date, it is represented by three main formats –\u00a0\u00a0HDR10\u00a0,\u00a0\u00a0HDR10 +\u00a0\u00a0and\u00a0\u00a0Dolby\u00a0\u00a0Vision\u00a0.\u00a0Accordingly, when choosing a TV, buyers are wondering which one is better, because different models support different\u00a0\u00a0HDR\u00a0technologies .

\n\n

The higher this setting, the more colors the TV can display.\u00a0Most screens on the market today are 8-bit, that is, capable of transmitting 16.7 million colors, within which content is usually created in\u00a0\u00a0SDR\u00a0<\/b>\u00a0– standard dynamic range.\u00a0However, premium TVs have 10-bit color depth, supporting over a billion colors.<\/p>\n
Peak Brightness<\/h2>\n
Consider the following table.<\/p>\n
\n\n
\n <\/td>\n HDR10<\/b><\/td>\n HDR10+<\/b><\/td>\n Dolby\u00a0\u00a0<\/b>Vision<\/b><\/td>\n<\/tr>\n \n Peak brightness of real content during editing, nits<\/td>\n from 400 to 4,000<\/td>\n from 1000 to 4000<\/td>\n from 1000 to 4000<\/td>\n<\/tr>\n \n Format technical limit, nits<\/td>\n 10,000<\/td>\n 10,000<\/td>\n 10,000<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Metadata<\/h2>\n
The key difference\u00a0 between the\u00a0HDR10\u00a0<\/b>\u00a0format and others is that it uses static metadata.\u00a0This means that when displaying content, the TV receives instructions on, say, the brightness range at the very beginning and adheres to it until the end of the display.\u00a0The brightness range of the brightest scene is taken as the basis.\u00a0It is easy to guess that dark scenes with this approach are often transmitted not in black, but in gray.<\/p>\n
Tone mapping<\/h2>\n
<\/p>\n
Content prevalence<\/h2>\n
The\u00a0\u00a0HDR<\/b>\u00a0format has grown rapidly in recent years.\u00a0HDR10,\u00a0<\/b>\u00a0due to its simplicity and openness, is the most common, followed by\u00a0\u00a0Dolby Vision<\/b>\u00a0, popular in Hollywood studios and streaming applications.\u00a0HDR10+<\/b>\u00a0is the newest of the trio and is still behind in adoption.<\/p>\n
TV support<\/h2>\n
HDR10\u00a0<\/b>\u00a0is supported by a large number of TVs today.\u00a0As for the other two formats, there is a division among large manufacturers.\u00a0So,\u00a0\u00a0Samsung\u00a0<\/b>\u00a0supports\u00a0\u00a0HDR10 +<\/b>\u00a0and does not accept\u00a0\u00a0Dolby Vision<\/b>\u00a0, while\u00a0\u00a0LG\u00a0<\/b>\u00a0and\u00a0\u00a0Sony<\/b>\u00a0, on the contrary, are supporters of\u00a0\u00a0Dolby Vision<\/b>\u00a0and reject\u00a0\u00a0HDR10 +<\/b>\u00a0.<\/p>\n
Conclusion<\/h2>\n
As for the choice of a TV, we advise you to pay the main attention not to the support of a particular format, but to its characteristics.\u00a0After all, the quality of the screen itself plays a key role in providing an entertaining viewing experience.<\/p>\n","protected":false},"excerpt":{"rendered":"
