HDR10+ is an open, royalty-free HDR (High Dynamic Range) standard developed by Samsung, Panasonic, and 20th Century Fox. It's an evolution of the HDR10 standard. It uses dynamic metadata like Dolby Vision, which allows for more precise and accurate reproduction of HDR content.
One of the critical benefits of HDR10+ is dynamic metadata. HDR10 uses static metadata, meaning each video frame's brightness and color levels are set during mastering. HDR10+ allows the display to adjust each video frame's brightness and color levels. This results in a more precise reproduction of HDR content.
Another critical benefit of HDR10+ over HDR10 is the support of a wider color gamut. HDR10+ supports the Rec.2020 color space, which is wider than the traditional Rec. 709 color space. Rec.2020 means that HDR10+ can display more colors than conventional displays, resulting in more vivid and lifelike images.
HDR10+ also offers better contrast than HDR10, making images appear more detailed and realistic.
While HDR10+ is considered an advancement over HDR10, it still needs to be more widely supported than HDR10, but its adoption is expected to increase.
Compression: Dolby Vision supports a higher compression rate than HDR10+, which requires less bandwidth to transmit the same amount of information.
Automatic tone mapping: Dolby Vision automatically maps the HDR content to the display's capabilities, which ensures that the content is displayed correctly regardless of the display's capabilities.
