Sigma Designs to offer HDR10+ in STV7803/4 UHD HDR Chipsets
Sigma Designs® has announced that universal HDR chipsets  STV7803 and STV7804 will now support HDR10+ . Samsung Electronics recently introduced this  new open standard (ST.2094-40) for high dynamic range (HDR) video called HDR10+  that leverages dynamic metadata to produce enhanced contrast and colors, making television pictures more life-like.

HDR10+ is an open-standard, royalty-free protocol and part of SMPTE2094 technology standards, which adds scene-by-scene Dynamic Tone Mapping. This innovative feature adjusts brightness levels in real time during video playback, continually optimizing picture quality to the degree achievable by each individual display panel using it.  HDR10+ is an evolution beyond the original HDR10 specification, adding dynamic metadata as opposed to static metadata. In practice, HDR10 compromises picture quality particularly for darker and brighter scenes as a single static setting is used for the entire duration of the content. In comparison, the metadata in HDR10+ Dynamic Tone Mapping continually adjusts the range of brightness, adapting in real time to specific scenes or even individual frames. With HDR 10+, dark scenes are darker, bright scenes are brighter, and visual content is dramatically more compelling than through the static single setting of HDR10.

According to a new report from Strategy Analytics’ Intelligent Home Group, annual worldwide sales of HDR-enabled TVs in 2020 will reach 58 million units, bringing the number of homes with at least one HDR-enabled TV to 107 million. The report further projects that HDR TVs will reach nearly 25% of homes in the US by that time frame.
