Flexible, reliable and high-performing cont'd...
high-quality 4K signals reached various
platforms for global audiences. Kiloview's
N60 provided the solution by integrating
easily
time, low-latency
into their workflow, enabling realstreaming
without
compromising on quality or network efficiency.
Zuo says, this solution not only met their technical
requirements but also helped optimise costs by
eliminating the need for additional devices.
Next Generation Audio (NGA) supports ChannelBased
Audio along with Object-Based Audio. This
combination enables functions like personalised
audio to be delivered to the viewer, where the
viewer's receiver mixes the final presentation.
Bolin specialises in broadcast and ProAV indoor
and outdoor PTZ cameras. Many of its cameras
are used in an SDI workflow. However, broadcast
studios and ProAV applications are increasingly
AVoIP environments or hybrid workflows. " Bolin's
cameras are outstanding performers in these
situations, but video flows need a flexible, reliable,
high-performing decoder, " explains the firm's Tim
Godby. " This is why we made the EG40 series edge
decoders. "
The EG40 decoder series is described as a
for
powerful, FPGA-based
platform created
broadcast customers but offering advantages to
everyone. The appliance operates on a standard
1Gbps network, decoding a single video flow
with audio and simultaneously outputting the
combination through its 12G-SDI and HDMI 2.0
ports. In addition, the EG40 series can upscale
1080p video to crystal-clear 4K60.
" This is a significant advantage for customers in
many ways, providing the ability to simultaneously
output 4K video to a large screen and a recording
device, for instance, " Godby says. " The latency
performance of the EG40 series is ultra-low. The
EG40 can decode AVC, HEVC, RTP, RTSP, and SRT
streams. The Dante AV-H and NDI (High Bandwidth
and HX3) versions add those flows, making it a
powerful, flexible IP decoder.
" Finally, the EG40 series can discover multiple
supported video streams on the network and
store them as visual presets, making switching
between them easy
and
convenient.
These
features distinguish the EG40 series, which offers
unique advantages and significant benefits to our
broadcast, education, video conferencing, and
House of Worship customers. "
Sencore has been focused on the contribution
and primary distribution decoding market
for some time. These applications have
seen great change in technology over the
years, explains Aaron Doughten, Director
of Technology and Marketing. " Baseband
workflows have evolved from 3G, to quad
3G to 12-SDI, and most greenfield contribution

Encoding next-gen audio
N
ext Generation Audio - or NGA - describes audio
codecs that not only support immersive audio,
but offer a multitude of additional features from
personalised and object-based audio to improved
audio description capabilities for visually impaired
viewers.
Larry Schindel, Senior Product Manager, Telos
ADM (S-ADM)
Alliance explains: " Serialised
metadata is the final item required to enable NGA
workflows in practice. At its basic level, it describes
what the audio is; whether the audio
is a bed mix and how many channels it
contains (perhaps 5.1 or 5.1.4), what the
various dialogue objects are, how the
audio elements are laid out in the SDI
or SMPTE 2110 stream, along with which
combinations of dialog and bed mix the
viewer is allowed to choose from.
" S-ADM is
broadcast
carried
through the
chain, from production
all the way to transmission and is

ultimately fed into a Dolby AC-4 or an
MPEG-H encoder; and is included in the
bitstream delivered to the viewer. This
metadata bubbles up to the receiver's
UI and allows the viewer to easily select
which presentation (combination of
audio elements) they wish to listen to. "
Schindel
highlights Junger Audio's
flexAI platform for the creation and
modification/manipulation of S-ADM
metadata at various parts
of
the
broadcast chain. It can also provide an operator
with a rendered output, either for monitoring / QC
purposes or to provide a complete program mix to
an encoder for an existing HD service where NGA
is not supported. Delivering S-ADM in a SMPTE ST
2110 environment has already been worked out and
is handled by transporting the metadata in a ST
2110-41 stream.
FranceTV used S-ADM during the Summer Games
in Paris to deliver 5.1.4 immersive audio with a
personalised language experience.

to grow. Transport protocols like SRT, RIST and
Zixi have made waves in the contribution and
primary distribution workflows around the world.
Along with these technical hurdles, budgets have
become tighter, and broadcasters are expected
to do more with less, or gain efficiency in existing
systems. "
Sencore's MRD 7000, " a true Swiss army knife "
for contribution and distribution environments,
directly addresses these issues. The MRD 7000
supports a wide variety of input options and the
latest
transport protocols, including SRT, RIST,
and Zixi, ensuring flexible integration across
workflows. With both SDI and IP outputs, it bridges
traditional SDI infrastructures and ST 2110 IPbased
workflows, including 12G/Quad-3G/3G-SDI
outputs and ST 2110 with ST 2022-7 redundancy in
a compact 1RU form factor.
" Designed for versatility, the MRD 7000 decodes
up to four services simultaneously, delivering an
ideal cost-per-channel solution that scales to meet
a wide range of system requirements, " Doughten
says. " Recently, a large-scale
broadcaster
employed the MRD 7000 to streamline a live sports
production. The device's multi-service decoding
capability, coupled with its support for both SDI
and ST 2110 outputs, enabled seamless, lowlatency
4K video delivery over IP at a fraction of
traditional infrastructure costs.
" With the MRD 7000, broadcasters

current and next-generation workflows, addressing
both technical and financial pressures head-on. "
