Viarte SDR to HDR/HLG Up-Conversion
Our latest proprietary superior Viarte
SDR to HDR up-conversion provides a solution for content creators and service distributors to
up-convert legacy 8/10-bit Rec709 SDR content to 10/12-bit HDR. For example,
this includes conversion to ST2084 at 1000 nits, 1500 nits, 2000 nits, or HLG at 1200 nits, with DCI-P3-D65 and BT2020 color.
It takes full advantage of the latest HDR display technology advancements 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 dark
details, 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, 1500 nits and 2000 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 or UHD Phase 1 content.
In particular, it complements our advanced vivid HDR to SDR conversion, i.e. HDR can be first tone-mapped down to SDR and
then up-converted back to HDR at 1000 nits for example. The down and up-converted results are very close to their
more direct 1000 nit HDR counterparts (either originally at 1000 nits, or directly tone-mapped to 1000 from higher levels).
This allows conversion to be used in a single stream, backwards-compatible SDR distribution.

Inverse tone-mapping, in conjunction with viarte MC noise reduction, achieves a combination of stunning
picture quality and significant bandwidth savings beyond HEVC. Please check out our latest publication

Viarte automated SDR to HDR up-conversion breathes new life into valuable legacy content for the emerging HDR
display market, and together with Viarte vivid HDR to SDR tone mapping, help propel no-compromise HDR
Demonstrations of the latest isovideo SDR to HDR/HLG up-conversion have been given
at SMPTE Dolby Ballroom Exhibition booth #110, Hollywood, California. October 24-26, 2017.
