Our very first 4K Blu-ray Player the CXUHD is finally here and already making its way to movie fans taking the next step in home cinema perfection. The latest addition to the CX series utilises a relatively new technology that is looking to improve visuals known as Dolby Vision. We’re going to explain what it is and how you can benefit from it.
Before we get stuck into Dolby Vision, it’s worth talking about HDR first (which we briefly touched on in one of our last blogs). HDR or High Dynamic Range refers to an image that displays far greater contrast than regular images (Standard Dynamic Range, or SDR). The dynamic range of an image is the difference between its brightest and darkest areas. The higher this range, the higher the amount of available colours, and levels of detail, on screen.
So What is Dolby Vision?
In a nutshell, Dolby Vision is another type of HDR, but more advanced with some significant differences to know about. The process of implementation flows from initial content creation, through to mastering and then, finally, to the viewing experience at home. Dolby Vision HDR carries an extra layer of clever metadata that contains frame by frame instructions to ensure the content is portrayed as accurately as possible. Dolby Vision compatible TVs use this frame by frame information from the source to improve brightness, contrast and colour performance. Regular HDR simply sends a static, basic form of metadata that applies to the entire TV show or movie you’re watching. Dolby Vision can be transmitted through HDMI 1.4 devices and up, which means that an AVR with an older format can fully take advantage of the technology. Standard HDR content will still be seen by Dolby Visions compatible TVs, but will just display regular HDR metadata improvements.
