SHOW REVIEW ISE 2020
The company launched its rst
50,000 lumen project with only blue
lasers however, but at ISE they were
debuting a new, compact 3DLP LCD
projector, with an output of 30,000
lumens.
Thomas Vertommen, European
product marketing manager for
projectors at Panasonic said, “At the
end of December, we delivered the
rst 50,000 lumen projectors with
native 4K 3DLP, but with a light source
that, instead of the traditional laser
phosphor, with only blue lasers, we
added a red laser on top of it. We
then changed the bandwidth of the
blue laser so that it improves colour
reproduction and opens up the colour
space.”
Vertommen also said that when it
came to eSports presentations, the
set up can contain a mix of panels and
projection and also revealed that a
black projection screen can add to the
content.
“If you do these types of events,
most of the time designers go for an
LED wall as a back screen. We are
using a 50,000-lumen projector on a
special black projector screen, which
can achieve a much higher contrast,
and it attains the same brightness,
same colours or contrast as an LED
wall but with the advantage that it is
more cost ef cient.
“Projection is easier and quicker to
set up because an LED wall takes a lot
of time to build and put together every
single tile, align it, make sure that all
of the signals are looped through. With
the combination of just a projector and
a screen, it’s not something that takes
hours or days.
“Most importantly, if you look at
it from a camera perspective, it’s
a lot easier to get better footage
because you don’t have this pixel
pitch, you don’t have the Moray
effect that always comes in. Normally
cameras need to have some technical
developments to overcome that effect
but with a projector, it’s completely
irrelevant because that effect never
happens.”
Controller
Panasonic used its own IP switching
platform in order to control the content
on screen. While such a system is
not necessarily new, both Xilinx and
Vitec were showing off compression
technology that lowered the time it
takes to distribute content
to the desired screen.
Vitec was promoting
its EZTV multicast
solution that condenses
content from the point
or origin, or head
end, sends it through
to an edge server
decompresses and
want. So, if you wish to have a triangle
effective you can still send the video
to that.”
Bandwidth was also on the mind
of Xilinx, who launched new machine
learning demos with the ability to
reduce the bandwidth needed to
distribute content by reducing the bits
applied to the areas of the
screen that would not
naturally attract the
human eye.
However, capturing
that content is still key,
a fact that Xilinx has
attempted to overcome.
Seeing the limitation
of having a few or a
single camera, Director
of Pro Audio, Video and
Broadcast business
and Consumer business
Ramesh Iyer explained how the Xilinx
ML system is giving more framing
options.
“The machine learning engine
combined with the video codec that
we’ve integrated, combined with a very
powerful ARM processor, a powerful
graphics engine, the FPGA fabric built
into the system allows our customers
in nite amount of exibility into the
way they want to deploy the solution.
“For a person at a school sports
event, you only have one camera. But
when you want the viewers to see
multiple angles of this camera, how do
you do it? One option is you buy more
cameras and install them but instead
we’ve come up with a technique where
a single camera can focus on the
entire 4K frame and inside that frame,
you can have multiple 1080p HD
windows based on what you want the
machine learning engine to focus on.
“You may want to focus on the
football, or you may want to focus
on ads, or you may want to focus
on somebody’s t shirt, or the player
himself or herself. The machine
learning engine ts all of them into
different windows based on what it’s
looking for. So, a single camera can
then produce multiple outputs.”
“Projection
is easier and
quicker to set up
because an LED
wall takes a lot of
time to build and
put together.”

Vertommen
distributes it to the
end points. A solution that uses less
bandwidth to distribute the content.
“We have a true multi cast edge
to edge solution, which is why it’s
quite unique from the headend, which
is what’s bringing in your content,
satellite, TV mass, we can then either
take that through gateways or encode
it and make up the stream that you
can then distribute.
“Then we have bolt-ons to that
ecosystem, one of which is digital
signage which is a fully integrated
compliant digital signage product
that works with the EZTV system and
means that any graphics and videos
can be put in a layout to suit your
individual needs.
“Beyond that, we also have video
processing, which has the capability of
having a display, put across multiple
TV screens in any layout for what you
