HDR/HFR/UHD Trends and Challenges Facing the Media Industry &
How Viarte can Help
HDR Processing and Distribution
Challenge: HDR provides a more vivid image due to higher local contrast, higher brightness and increased dynamic range.
However HDR requires high precision computation and higher distribution bitrates due to increased detail and noise.
HDR production also need to be future proof in terms of maximum brightness and HFR. Furthermore, high quality backward-compatible HDR distribution
to majority of current SDR displays, especially to mobile as well as HDR live event broadcast, remains a challenge, at least for a foreseeable future.

Noise in HDR/SDR Digital Media & Online Distribution
Challenge: internet video traffic is exploding, due to higher demand, HFR, HDR, and UHD, but available bandwidth lags in comparison.
Noise is an inherent property of most digital media, and may spoil viewing immersiveness, while also preventing
HEVC/H.264 compression from achieving low bit-rates.
Common practice: intra-frame noise reduction and lowpass filtering prior to encoding, with heavy HEVC/AVC
compression. These practices can significantly degrade picture quality.
Goal: bit-rate reduction without sacrificing picture quality.
Solution: Viarte GPU-accelerated, HDR/SDR detail-preserving motion-compensated (MC) noise reduction prior to lossy compression using HEVC/VP9/AVC.
Benefits: Provides an engaging & immersive viewing experience from noisy video, while significantly saving
online distribution bandwidth for HEVC/H.264 compression upto 5x for the same or better PSNR.
Larger Displays – Ultra HD/4K and 8K
Challenge: provide an immersive viewing experience for all type of content, ranging from SD to 4K.
Problems: without excellent preprocessing, picture quality may look worse on large displays with increased brightness and dynamic range.
These displays magnify and accentuate noise, blur, motion judder, as well as processing related artifacts due to deinterlacing, FRC, and crude noise reduction.
Goal & Benefits: to provide smoother, sharper, cleaner and smaller-footprint video from all sources, including
different noise levels, frame rates, scan types, encoding types, etc.
Viewers can then truly benefit from these vivid and larger/brighter displays, while distribution network bandwidth is reduced.
HFR Capture for Applications such as Sports & Film
Challenge: high quality frame rate conversion for re-distribution at different frame rates, such as at
lower frame-rates at 24p/25p/30p from sources of 120p,
at higher and lower frame-rates such as 50p/60p and 24p/25p/30p (including fractional rates) from 48p.
Problems and common practice: Poor conversion methods or adhoc conversion (such as dropping or duplicating frames) often results in unpleasant
visible visual artifacts (even at normal viewing speed) such as global ghosting, boiling effects, blur, and judder.
fast, GPU accelerated,
accurate any-to-any up/down-frame-rate and/or resolution conversion with optional simulated
motion-blur to effectively reduce judder without visual artifacts while also reducing H.264/HEVC compressed bit-rates.
IP/file-based studio workflow
Challenge: reduce file-based video processing latency and increase throughput for standards conversion, digital remastering and HDR to SDR tone mapping.
Problem: file-based workflow requires subsequent processing to wait until up-stream processing completes. UHD, HFR, and HDR all
combine to dramatically increase the amount of data to be processed.
Solutions: Viarte efficient splitting technology and 4k realtime lossless compression enables low-delay processing, efficient scalability and 4k realtime display/transmission over 10 Gbit IP.
Benefits: i) Fast turn-around IP-studio workflow, ii) New Applications: Live-feed and archive productions.
State-of-the-Art Viarte Technologies for
Vivid - Sharper - Smoother - Cleaner - Smaller-footprint HDR/SDR Video
Nearly 70% of existing video is marked as interlaced - it is still prevalent in many studio and distribution systems.
Interlacing is easy to achieve, but deinterlacing to high quality progressive is very challenging.
Furthermore it can be shown mathematically that perfect deinterlacing is impossible to achieve.
Deinterlacing or inverse telecine, if needed, are the very first steps in a video processing chain.
Since content transformation, often involves a chain of digital processing steps,
errors at the start from poor deinterlacing / inverse telecine, may be further accumulated and magnified in
subsequent processing steps involved in digital remastering/standards conversion (such as
frame rate conversion, scaling, noise reduction, encoding, etc.), leading to unavoidable visual artifacts.
In addition, inferior deinterlacing often requires an output lowpass filter to reduce artifacts and flicker,
resulting in a much blurrier image than its true potential.
Inverse telecine often is done incompletely due to noise, or poor handling of mixed/broken/random cadences.
This not only gives interlaced-looking frames, but also results in many unnecessary duplicated and/or dropped
frames, leading to severe visual artifacts and playback judder.
Viarte achieves the best quality MC deinterlacing results available today. It is the only technology offering
100% vertical resolution with very little or no visible flicker. Furthermore, at that resolution, it
achieves a substantial 21% average bit-rate reduction in HEVC/H.264 versus compressed interlaced - a
truly objective measure of deinterlacer quality.
MC Frame Rate Conversion (FRC)
Simple FRC approaches do frame dropping/duplication to achieve a new frame rate, which introduces objectionable
motion judder. The next level up - linear blending converters - produce objectionable ghosting effects with
visible motion judder on sharp edges in pans. More advanced motion-compensated converters commonly produce
'boiling'-type artifacts around edges.
Viarte MC FRC produces sharp, judder-free results for all input frame rates 24p and
up, with no duplicated frames or visible artifacts at normal playback speeds.
Scaling, if done well, gives a much more immersive viewing experience on the same size displays.
Scaling is often done poorly, introducing blur and ringing on edges.
Viarte scaling really 'pops' each frame out to the viewer, for a surprisingly immersive experience.
Even older SD material looks noticeably sharper when upscaled.
