audio codecs. This would include
hardware codecs, tablet-based apps,
smartphones and desktop computers.
" Systembase IP Codecs have
been designed to enable multiple
simultaneous connections from a
single unit, " explains the firm. " A
connection can be made or broken
without disrupting other connections
that may already exist. When making
a connection to a remote codec,
the user can specify the audio to
be duplex, receive only or transmit
only. If the receiving codec is not
able to implement the requested
audio mode due to a conflict with
an existing connection, Automatic
Negotiation will take place to provide
a suitable operating mode. Automatic
Negotiation allows the remote codec to
connect without any prior knowledge
of the local codecs connection status. "
In the event of power failure the
C510ip-s can re-boot, negotiate and
restore an IP audio connection to its
streaming state in approximately 10
seconds. This feature is perfect when
the codec is being used for commercial
applications such as transmitter links
or live commentary.

IQOYA CONNECT cloud-based
infrastructure.
Audio content is streamed through a
large number of wired or wireless 'last
mile' connections. Digigram explains
that IQOYA TALK builds reliable, ultralow-latency
audio contribution links
over WAN, WIFI and 3G/4G networks.
Its reliable streaming engine enables a
bidirectional, high-quality connection
from the field reporter(s) to the main
studio.
Tieline's
broadcast
customers
say
they want to do more with less. In
other words, fewer boxes, using less
space, with lower power consumption
and more functionality.
" Flexibility and more interoperability
are key, " explains Charlie Gawley,
Tieline's VP Sales APAC/EMEA.
" Broadcast engineers want an AoIP
appliance that can transcend multiple
technological standards and that
traverses across your LAN, WAN and
Public Internet, a gateway of sorts with
simple monitoring and control. "
Tieline's latest offering is the
Gateway AoIP multi-channel codec
that natively supports traditional
analogue and AES3 I/O interfaces.
More importantly, straight out of the
box it supports open Audio over IP
standards such as AES67, RAVENNA,
and ST-2110-30 for those in
the TV world, providing a high
degree of interoperability with
proprietary protocols such as
Dante and Livewire+ (in AES67
compatibility mode).

IQOYA TALK, available from
Digigram, is a portable IP audio codec
dedicated to live remote broadcasting
for radio and TV. Designed by with
an intuitive user-interface as simple
as a smartphone, IQOYA TALK allows
remote reporters to perform all the
key actions in just two clicks. Live
reporting or commentary can be
performed, as well as studio quality
interviews for up to four journalists
and guests, with a user experience
" The transport of audio is just
one piece of the puzzle that is why we
have added NMOS IS-04, RAVENNA
and SAP for discovery and NMOS
IS-05 and EMBER+ for control and
logic, " says Gawley. " There is also an
optional WheatNet-IP audio interface
available. "
In addition, the Gateway supports
SIP interoperability standards for IP
audio codecs, those being EBU3326
(Audio Contribution over IP) and

2wcom's 4audio solutions link well-known
and new broadcast technologies as well as
stationary and remote studios
EBU3347 (Intercom over IP). This
enables the codec to interface with
non-Tieline audio codecs, or be a
SIP
trunk-based
gateway
for
your
communication circuits between
multiple venues at large sporting
events across the public internet.
The
MoIN
-
Multimedia
over
IP
Network - is a software solution
from 2wcom that is able to encode,
decode and transcode multiple
audio channels simultaneously. It
is designed for studio to studio and
studio to transmitter links, as well as
cross-media tasks. MoIN supports all
established standards and protocols
like AES67, RAVENNA, Livewire+,
Dante, SMPTE ST 2110, SRT, Ember+,
SIP, SAP, PTPv2 and RTSP, as well as
transcoding from one format into the
other.
2wcom says the solution provides
all functionalities that traditional
hardware
AoIP
codecs
offer.
The
company also points out that it adds
benefits such as scalability, usageoriented
pricing models, optimized
rack space or flexibility in application.
The system features Icecast to DVB
transport stream transcoding so web
streams are available on DVB transport
stream for distribution in cable
networks or via satellite. In addition,
its software can feed a streaming
encoder or transcode an audio signal
to adaptive bitrate protocols like HLS
for further distribution via CDN.
Available as hardware or virtualized
software, 2wcom says its new
MoIN multimedia over IP network
server eases the day-to-day work of
network operators. Due to its new
and advanced technological concept
it assures outstanding flexibility in
application and offers a high-level
compatibility which is especially
important in mixed networks and
expanded infrastructures.
MainConcept's audio focus is on
ABR (Adaptive BitRate) streaming - a
curious concept perhaps because when
people talk about ABR, the focus is
usually on video, while audio typically
plays only a minor role or is entirely
neglected. It's true that video takes
up considerably more bandwidth
than audio, but for most production,
high-quality audio is anything but
an afterthought. The common audio
standard is AAC but Fraunhofer IIS
- which co-devised AAC - recently
released a successor, xHE-AAC,
which has already been deployed on
countless Android and iOS
devices.
Even Netflix has identified xHE-AAC as
the key audio format.
" The seamless switching between
various quality levels and audio
bitrates makes xHE-AAC more
flexible
than
extended
legacy AAC formats, "
says MainConcept. The company
has
its
highly
acclaimed
FFmpeg product line by adding the
beta MainConcept xHE-AAC Encoder
Plugin for FFmpeg. Although the
audio bitrates are often neglected
when it comes to bandwidth savings,
xHE-AAC deploys a unique approach, "
MainConcept explains. " The audio
bandwidth you save with low bitrate
xHE-AAC can be used for improving
the overall video quality. This saved
bandwidth
can
often make certain
areas or textures within a picture
clearly visible and distinguishable
again. After all, every bit counts! "
