What HDR formats (Dolby, Philips, .. etc) are provided, the BDA has not yet been announced. Defined in the standard are also new, object-based sound formats such as DTS: X and Dolby Atmos. Trendsetting is defined in the Ultra HD Content Standard (BT.2020) support for 10-bit color depth and color space Rec.2020(See chart), which provides a much higher color area opposite the Rec.709 currently used - but still no TV currently supports the Rec.2020 color space.
