What’s HDR?
Currently TV standards are based on Standard Dynamic Range metrics which were established more than thirty years ago. HDR
enabled TVs will be able to display a significantly expanded range of both colour and contrast, delivering what is known as High
Dynamic Range (HDR). In other words, HDR enabled TV’s will expand the contrast ratio and colour space to offer a more realistic and
natural image closer to the way your eyes actually see the real world. Deep blacks are combined with very bright highlights to produce
a level of reality not previously possible.
Before: Standard Dynamic Range (SDR)
Resolution: SDTV/HDTV, Colour Space: Rec.709, Brightness: 100-300nit
The expressible brightness range is narrow, making images appear darker than in the real world.
Now: High Dynamic Range (HDR)
Resolution: 4K Ultra HD, Colour Space: BT2020, Brightness: 1,000nit
The expressible brightness range is expanded, and the amount of colour information is increased in dark and bright areas.
HDR enabled TVs delivers images closer to the way you see the real world
Next-Generation New HDR Format: HDR10+
What's HDR10+?
HDR10+ is an open, royalty-free dynamic metadata platform for High Dynamic
Range (HDR), created by 20th Century Fox, Panasonic, and Samsung.
Together the 3 companies have formed a licensing entity that will begin licensing
the HDR10+ platform in January 2018.
HDR10: Static Tone Mapping
With static metadata, one fixed tone mapping curve is applied across the whole film
based on the scene with the highest luminance, meaning that some scenes may be
displayed sub-optimally.
HDR10+: Metadata Tone Mapping
With HDR10+ dynamic metadata, the tone mapping curve is adjusted
scene-by-scene to enable the most optimal visual reproduction for each scene.
Furthermore, the ease of authoring video content will lead to much more HDR film
and episodic content becoming available.
Optimised only for the brightest scene in the content
Optimises each scene
What’s “Metadata” ?
There are two types of metadata.
•Static Metadata － HDR10 (Fixed based on content)
•Dynamic Metadata － HDR10+ (Brightness information
adjusted scene-by-scene)
→ The image is optimised for each scene
Panasonic delivers an Incredible HDR Experience
1) HDR Metadata Creation
Panasonic's unique processing technology creates metadata and adds it to normal HDR10 signals. This turns even conventional
HDR into more lifelike images.

HDR Metadata Creation
Analysis and tone mapping are adapted to each scene.
Even non-HDR10+ content reproduces real, lifelike images.
2) HDR Brightness Enhancer
Automatic Adjustment
The images in dark scenes are difficult to see in bright room conditions.
A sensor built into the TV detects the room brightness and automatically adjusts the HDR picture quality to match it.
You can enjoy images with excellent contrast and colouring
even in a brightly lit room.
Manual Adjustment
HDR can also be manually set. Content and personal preference can be optimized in 15 steps.
Setting can be done with the menu's HDR Brightness Setting.
The 15 steps can be switched.
