Dolby Vision , one of the key technology might provide a best experience on whatever you see. This plays in key role in Studios, Films, and many more.
You might noticed that a label on Premium TV's shows Dolby Vision support. It is also included in High performing Gaming console and Flagship Smartphone's. So let's get into the blog.
WHAT IS DOLBY VISION:
Dolby Vision is a type of HDR display which enables the user to get a better experience ever on whatever you see. Also, you would possibly find Dolby Vision on many in-store advertising and inside your gadgets or devices. It makes a game-changing advancement, and it’s one that TVs have needed for a decade.
*Note:4K brings us additional pixels, but it's HDR that enhances those pixels really shine like a way they never have before.
Make a note that not all HDR TVs will come with this dynamic HDR format. The basic HDR10 is a minimum requirement for a Device to support Dolby Vision.
HOW IS THIS POSSIBLE:
The reason is that it places an additional layer of information on top of a core HDR10 video signal which contains scene-by-scene information. This can be used to improve the way of presenting the pictures. So that the screen better brights and darker blacks, and this enables Screen to display full range of colors.
WHAT IS THE USE OF DOLBY VISION IQ:
At CES 2020, Dolby presented its new video technology Dolby Vision IQ, which is actually an upgrade to Dolby Vision. The software uses light sensors built into the new Dolby Vision IQ-enabled TVs which effectively adjust Dolby vision content for optimal and better viewing. This feature makes Dolby Vision ultimately dynamic. It senses the ambient light level in your room and changes the extra color and contrast info accordingly. It also readjusts on a scene-by-scene basis to fit your viewing conditions. LG and Panasonic support IQ are currently the sole manufacturers that support Dolby Vision.
The Dolby Vision IQ uses the dynamic metadata encoded in Dolby Vision content in conjunction with an embedded light sensor within the TV. Using this knowledge to vary the image settings and display a more accurate picture.
Dolby Vision IQ can tell that you’re watching TV during a very brightly lit room, where many dark details are getting lost. The TV will therefore be ready to boost the brightness automatically without you having to travel into the image settings and make out yourself. Dolby Vision IQ also helps to vary picture settings to suit the sort of content being watched (movies, sports, etc).
WHICH DEVICES SUPPORT DOLBY VISION:
The Dolby Vision is compatible for all types of devices. This might be a set-top box, game console, or Blu-ray player for your streaming video content.
Streaming devices just like the Roku Streaming Stick+, as an example , only support HDR10.In contrast to that, some Roku TVs that is made by TCL, supports Dolby Vision. In addition to the Roku Ultra streaming box supports Dolby Vision effectively.
The Apple 4K TV also supports Dolby Vision. where as the Apple TV HD do not support Dolby Vision. Also, the Nvidia's Shield TV and Shield TV Pro supports Dolby Vision.
Amazon’s 4K Fire TV Stick is one among the few devices that supports all four of the highest HDR formats: HDR10, HLG, HDR10+, and Dolby Vision.
The Microsoft Xbox One S and One X supports Dolby Vision since 2018.But the Sony’s PlayStations do not support Dolby Vision.
At last, the Dolby Vision device requires an HDMI cable (instead of the dongle-style that plugs directly into a TV) confirm you purchase an HDMI cable that's guaranteed to be compatible with Dolby Vision.
*Note: The HDMI cable should bear the name called “HDMI Premium Certified”.
DOLBY VISION vs HDR10+ vs HDR10:
HDR10, HDR10+ and Dolby Vision are the main HDR formats. Firstly, In terms of availability the HDR10 is an open-standard, and non-proprietary,HDR10+ is Royalty-free standard for HDR , whereas Dolby Vision requires license and fee from Dolby.
Dolby Vision produces a better picture quality and viewing experience, but there are no TVs that could take full advantage of what it provides as opposed to HDR10.
Dolby Vision offers a better image quality, mainly due to its dynamic metadata. Dolby Vision implements its metadata on a frame-by-frame basis, which makes it dynamic HDR. Dolby Vision can change color and brightness effectively, there by making the viewing experience more immersive.
HDR10 is static.HDR10 will set the same metadata for the entire film. With static metadata, the boundaries in brightness are set once for the entire movie and are determined by taking the brightness range of the brightest scene.
