BBC UHD Programmes will be HDR Almost all professional camera sensors are HDR!

–  “4K” BT.709 is no longer acceptable as UHD –  Many cameras exceed 14 stops dynamic range –  Low black level noise is important –  Not all camera electronics can handle HDR –  Few codecs handle HDR –  Camera set-ups are vital

UHD CONTENT

Viewing in the field (EBU TECH 3320) HDR Portable Displays

–  HDR •  HLG •  PQ •  SLog3

–  1500cd/m2 display –  Onboard recording –  3840 x 2160 10bit –  Cost - under $1200 US!

LOCATION IS TOUGH

SESSION 3 - HDR CAMERA USE

2018-08-24


HDR is about low-lights not high-lights Very low noise cameras

–  Allow natural look shoots –  Bring out colour detail in low-light areas –  HDR means

•  Highlights aren’t clipped •  Shadow detail isn’t crushed •  Fire and candles look natural

–  HDR does not reduce the lighting bill!

–  Conform and convert only what’s needed •  Master format matches highest delivery option •  Master codec matched highest delivery requirement

–  Grade and Finish in HDR only •  Noise reduction is important especially for dark scenes •  Monitor SDR at the same time •  How do we make sure the HDR is comfortable to watch?

Just the same as loudness Except eyes “accommodate”

–  The eye will adapt to bright images fairly fast –  The next dark scene will appear too dark –  Sudden dark to bright can hurt –  Sudden bright to dark will appear to loose detail –  BBC R&D testing has developed a simple brightness tool

What is our audience doing and expecting? Qualcomm Five Audio Trends

WE ALWAYS FORGET AUDIO IS CHANGING TOO

The Way We Listen Over 80 percent of consumers use their smartphones to store and stream music, taking advantage of the ease and variety offered by streaming services such as Spotify, TuneIn, and others.

Embracing Wireless People want quality audio everywhere, they also want devices they can use all day, every day, and take anywhere — whether it’s a pair of truly wireless earbuds they use when working out, or a portable speaker that they can take to the beach.

Demand For Quality What started as an audiophile requirement has gained momentum in mainstream consumer electronics. Consumers are now demanding wireless audio that doesn’t compromise on audio quality.

Expecting Smart Speakers and Virtual Assistants Consumers now want to be educated, entertained, or informed, simply by asking a question or giving a command. As cloud-connection grows, smart assistant capability is expected to be included in many more (if not all) devices.

Using “Hearable” Devices “Hearables” reflects the convergence of features from traditional audio devices and wearable technology in ultra-small form factors. Users want high quality audio combined with advanced features, including the addition of sensors for biometrics, algorithms for voice recognition, and support for cloud-connected ecosystems.

Final Thoughts –  Broadcasters will benefit from a graceful, non-disruptive introduction of

HDR. –  The majority of the audience will watch programmes on non HDR

televisions for many years. –  It is vital that the HDR systems allow easy automated conversion of an

HDR programmes to Standard Dynamic Range (SDR). –  Mapping of SDR to HDR will be key to mixing old and new content in HDR

programming and distribution. –  Creative practices in production should not have adverse effects such as

visual fatigue or discomfort when viewed for a significant period of time
