Viarte SDR to HDR/HLG Up-Conversion

Our proprietary advanced Viarte SDR to HDR up-conversion provides a superior solution for content creators and service distributors to up-convert legacy 8/10-bit Rec709 SDR content to 10/12-bit HDR. This includes conversion to DCI-P3-D65 in an ST2084 container for HDR10 at 1000 nits, or HLG at 1000 or 1200 nits. It takes full advantage of the latest HDR display technologies to allow legacy SDR material to be converted to stunning HDR.

Advantages of Viarte SDR to HDR Up-Conversion:

• Sharpness and local contrast is enhanced in general, with a substantial boost in specular highlights, as well as user-defined dark enhancement, while also preserving artistic SDR intent. Consequently, Viarte up-converted results look natural and vivid, bringing a truly immersive HDR viewing experience from most SDR.
• Allows fast up-conversion/inverse tone-mapping from Rec. 709 to ST2084 at 1000 nits, as well as HLG (ARIB STD-B67). Color conversion (between BT2020, DCI-P3-D65, rec601, rec709, etc.) is also performed as necessary.
• For 8-bit sources, contouring is nearly invisible when viewing converted output on a 10-bit HDR display.
• Fully compliant with the latest Rec. ITU-R BT.2100-0. Also correctly sets SEI metadata for HEVC, and HEVC master-display chromaticity and white-point settings, etc.
• No input metadata or extra encoding layers is required for SDR up-conversion, thereby simplifying distribution and reducing complexity of a possible silicon implementation in an HDR TV, or in a set-top box.
• Works for all SDR sources, including legacy progressive or interlaced, or UHD Phase 1 content.
• On-the-fly automated SDR to HDR up-conversion supports HDR display of SDR live event broadcasts and OTT streaming applications.
• In conjunction with viarte MC noise reduction, Viarte SDR to HDR/HLG achieves a combination of stunning picture quality and significant bandwidth savings beyond HEVC. Please check out our publication "HEVC Results from MC Noise Reduction of HDR Content".

Viarte automated SDR to HDR up-conversion breathes new life into valuable legacy content for HDR displays, and together with Viarte vivid HDR to SDR tone mapping, helps propel no-compromise HDR adoption worldwide.
