What is a Dolby Vision? Everything you need to know about HDR technology dynamic format – Part 1

HDR technology is one of the most important innovations in the television industry. Dolby Vision is one of the most important formats of this technology that has unique features.

Of all the new technologies that have come into the television industry, HDR has had the greatest impact on enhancing image quality. The impact of this technology was more than just changing the industry from Full HD to 4K. Of course, most TV manufacturers today are focusing their marketing focus on 4K or 8K technology and less on HDR.

HDR technology is not a a fix format. In fact, the term (High Dynamic Range) is using for a set of image formats that each have their own unique characteristics. 

Among them, Dolby Vision is more famous for its Dolby Labs product. Following on from this, let’s take a closer look at this format and answer some common questions about it: What is Dolby Vision and what is it like with other HDR formats? How can such a format be achieved?

What is HDR?

Before proceeding to the Dolby Vision format, you first need to know the main family, HDR. HDR allows content creators and filmmakers to produce brighter, higher-resolution videos and more contrast to older content. The format was generally broadcast in professional cinemas, but it was gradually introduced to home televisions. So today when HDR content is broadcast on a TV with this format, you can experience great cinematic quality on a smaller screen.

For HDR technology There are currently five HDR formats available for home users: two of them are Static and three are Dynamic. There are two static formats, HDR10 and HLG. HDR10 is supported by all HDR TVs. HLG is also generally use for media broadcasting. The static concept in these formats means HDR content is identified once based on the whole movie or TV show. The information obtained at the beginning does not change until the end of the play.

Dynamic HDR formats, unlike static formats, change information based on scenes and even image frames. In fact, HDR content creation elements vary for each scene and frame. Such an approach requires a lot of data, but experts believe the HDR format offers much higher quality in this method. Advance HDR from Technicolor is one of the dynamic formats. Two other formats for home content are more commonly uses: HDR10 +, which Samsung also developed, and Dolby Vision.

Dolby Vision Special Advantage

As mentioned, the Dolby Vision is a dynamic HDR format developed by Dolby Labs. This format gives the user more detail with higher color accuracy by adjusting scene-by-scene and even frame-by-frame. Content optimization is done separately in each image. Of course, the Dolby Vision process and method are more detailed.

Dolby Vision allows content producers to improve image settings at very minor levels. Plus, more settings than the traditional HDR10 format are supported in Dolby Vision. The HDR10, for example, supports maximum television (Nit) brightness. The figures for Dolby Vision reach 6,000.

The color accuracy of Dolby Vision is also increasing compare to other formats. The HDR10 allows manufacturers to program and adjust color with 2 bits of data. Dolby Vision delivers bits to 2 numbers. At first glance, such a two-bit difference may not seem like much, but it will certainly be more practical. With 2-bit settings, you can create 2.3 secondary colors from each primary color, giving the content creator just over a billion colors. When the setting reaches 2 bits, the choice of secondary color is increased to 1.3. Ultimately, it is possible for the content creator to choose from 3 billion colors.

Many of the details describe above are not so well understanding on today’s television. Currently, no television is capable of displaying 4,000 brightness nits and 2 billion Dolby Vision colors. Even the best products on the market with the highest lighting capabilities are limited to two thousand nits. Among the most professional televisions is the E family of LG products that support up to 2 bits of color. Ultimately, television technology is growing at a rate that could support Dolby Vision’s many capabilities for the next five years.

Difference with HDR10 +

The HDR10 + format supported by Samsung is very similar to Dolby Vision. The dynamic format with the ability to change settings for each scene takes a similar approach to Dolby Vision. The HDR10 + also supports a wider range of colors and light, but it’s not as professional as the Dolby Vision. Of course, the main difference between the two standards currently in place is their availability.

Some devices currently support HDR10 +, and there is not much HDR10 + content available. Of course, we will definitely see increased support and access to content and hardware in this format. Thanks to the extension’s free license, more manufacturers will definitely be interested.

The important thing about Dynamic Format Support is that any Dolby Vision format backup device will also support HDR10 + with Formor Update. In addition, such support is not too expensive for TV producers. Of course, this is not the case for Dolby Vision. Support for Dolby Vision requires licensing as well as development of formwork, and some manufacturers may not want to.
