What is HDR10+?
Technology sectors such as audio-visual equipment is an area littered with acronyms, some important, some less so, but of all of them perhaps the one with the most impact is the HDR10+ system, and the advances that it brings to the viewing experience.
HDR10+ is a High Dynamic Range format that adds dynamic metadata to the standard HDR10 signal. Rather than set the dynamic range to a static set of numbers, HDR10+ can set and change the boundaries, as it requires, based on the content your screen is displaying. That means you'll have better detail and a fuller range of colour, especially in scenes which display mostly light or mostly dark content.
This then begs the question, what is metadata and why is it important to something like a display screen? Metadata can be explained in three basic ways:
• It is data that provides information about other data in the system.
• It summarises basic information about data, making finding & working with particular instances of data easier.
• It can be created manually to be more accurate, or automatically and contains more basic information.
All of that means that metadata is important, and can be thought of as a shorthand notification of the data to which it refers. If we use analogies, we can think of metadata as references to data. The metadata concept is easier to think about if you consider the last time that you put a search term into an online search engine, such as Google. That search started with the metadata that stated certain things about something you wanted to find. You may have begun with a word, phrase, meme, place name, slang or something else.
The possibilities for describing things seems endless. Certainly, metadata schema can be simple or complex, but when created and handled properly, metadata serves the clarity and consistency of information. Metadata facilitates the discovery of relevant information and the search and retrieval of resources. Once effectively tagged with metadata, any digital object can be automatically associated with other relevant elements and thus easy to organize and discover.
While other systems – notably the impressive Dolby Vision – are well advanced in development, and have actually found their way onto some current devices, they are still regarded as products for the future. Dolby Vision itself is waiting for the hardware in TV sets to catch up with its potential, and while it might offer even better graphics, you may have to wait some time. Furthermore, Dolby Vision is a proprietary solution, and in order to use it, you need Dolby Vision-enabled content playing through a Dolby Vision-compatible player to a Dolby Vision-enabled display. The company has a certification process, licensing fees, and special hardware that manufacturers must include. That drives up prices for TV manufacturers and content creators, which makes things more expensive for the consumer.
HRD10+ is becoming more widespread, and if you want the best in displays then this is the system for you, and with heavyweights like Panasonic being dedicated to the solution, you can be sure of getting high quality product with great visuals.
