Samsung planning HDR10+ firmware update for 2017 UHD BD players

15 Jan 2018 | Rasmus Larsen |

At CES 2018, Samsung talked up the HDR10+ format and also revealed that it is planning to roll up a HDR10+ firmware update to its 2017 UHD Blu-ray players. Before that can happen, Samsung has a few kinks to iron out.

HDR10+ Blu-ray update

The update will make the UBD-M9500, M8500, and M7500 capable of reading and outputting video in HDR10+, the open format pioneered by Samsung. HDR10+ can – like Dolby Vision – use dynamic metadata to optimize video on a scene-by-scene basis.

Currently, there are no UHD Blu-ray discs available in HDR10+ format but 20th Century Fox and Warner Bros have committed to releasing content. Amazon is already offering content in the format via streaming, while Netflix has yet to comment on the matter.

So how is this possible without HDMI 2.1’s ‘Dynamic HDR’ feature? FlatpanelsHD reported in September 2017 that HDR10+ works over HDMI 2.0b. At CES 2018, Samsung confirmed this information and explained that it is using a solution called ‘Infoframe’. It can carry 24Kb of metadata in the signal, which can then be interpreted by the display.

A few kinks to iron out.

Samsung demonstrated this HDR10+ approach at CES 2018 during a private session with an UHD Blu-ray player running beta software. FlatpanelsHD noticed that whenever a scene changed, a short blink in the picture would occur, which negatively affected the viewing experience. We were not allowed to shoot video or take photos during the session.

We brought up the issue with Samsung’s engineers who explained that it was caused by a small lag between when the scene changed and when the dynamic metadata kicked in, meaning that the next scene would briefly adhere to the previous scene’s metadata. Samsung further said that it is working on a fix for the problem and that the certification process for HDR10+ will include testing for the issue.

A HDR10+ logo was also revealed at CES 2018.

Samsung did not say when exactly it expects to push out the HDR10+ firmware to its current UHD Blu-ray players, other than it is expected to roll out sometime in 2018.
