He believes that Samsung's AI technology will play a major factor "as that ecosystem grows." He adds, "We're continually
updating and improving our 8K AI
Upscaling engine to make viewing lowerresolution content even more appealing.
The next big milestone in the development and acceptance of 8K" is next-generation video game consoles that can
handle games developed in 8K.

content that will be part of the 8K landscape. At
first, 8K displays are being used to upscale existing movies and TV shows (including DVDs), but
much more is in the pipeline. Japan's NHK network plans to produce and transmit much of the
Tokyo Olympics (postponed until Summer 2021) in 8K format, and
YouTube is streaming limited content (mainly nature documentaries) in
8K. Marvel Studios produced the 2017 movie Guardians of the Galaxy
Volume 2 in 8K.
Japan's NHK has developed an 8K camera. The number of consumer
cameras capable of 8K video will increase, but for now there are only a few
devices. Among them are Canon's mirrorless EOS R5 DSLR camera that
can record uncropped 8K RAW at up to 29.97 frames per second. Samsung'
Galaxy S20 smartphone also has sensors and the Snapdragon 865 chipset,
enabling it to capture 8K moving images.
Philip Lelyveld, who leads the Immersive Media Initiative Program at
the University of Southern California's Entertainment Technology Center,
foresees a steady acceleration of 8K technology in content production.
"Storytellers like to work within the boundaries of technology," Lelyveld
explains. "Creativity likes limitations, so you have to think how to reach
beyond what's there now." He believes 8K will be "useful for exploration of
images or any sort of reality programming."
Lelyveld adds, "Artistically, the entertainment industry's goal is to create
engaging experiences. Resolution of the source material is both something
you see and an opportunity to explore. For live-action capture, resolution
has limited exploration potential. For game-engine real-time-rendered
content, the possibilities are infinite."
Lelyveld expects that the development of 5G wireless delivery will affect
the adoption of 8K and other higher resolution formats," including AR and
VR, which doesn't have a resolution limit." He also points to AI "not just to
create content, but to fill in and correct image problems." He envisions new
technologies, including VR/AR to create new environments that will
become part of the new mix in and beyond the "8K rectangle."

CLOSE-UP IS BETTER

8K screens display 33 million pixels that are tiny -
really tiny - even on
supersized screens that are
ten feet wide or larger. That
means the pixels can show
texture as well as color, hue
and brightness, the usual
core factors of a visual display. Viewers sitting close to
the screen can actually see
the image - the stitches in
clothing, the letters on the
page of a book, the details in
an avatar - and not be aware of the rectangular pixels making up the image.
Blacks are blacker and colors are stronger
(or more subtle) than on previous formats.
The images are also brighter. For example,
Sony's 8K sets show 10,000 nits (brightness measurement), which is more than
double the current brightest displays.
Behind 8K's UHD resolution is a slew
of new technology, especially processors
that use artificial intelligence (AI) to
upscale and display images. For example:
LG's Alpha 9 Gen 3 8K AI chip uses a sixstep process to reduce noise and enhance
the picture. Sony's X1 Ultimate chip uses
AI to recognize every object on the screen
and manipulate appropriately for the
image. Samsung's AI Quantum Processor
8K also uses AI and machine learning for
upscaling and to handle the action on
video game displays.
Set-makers are also intensifying their
production of other user experience
improvements, such as OLED, QLED,
High Dynamic Range and processors
such as LG's NanoCell.
These technical capabilities become
even more important with the new
