Visitors to IBC 2007 in Amsterdam will be able to see a
dramatically new addition to the Telos Systems Zephyr family of
broadcast codecs: The Zephyr iPort MPEG Gateway, a new codec that can
transport up to 8 channels of bi-directional stereo audio between
locations, using Quality-of-Service (QoS) guaranteed IP networks.
“Just as ISDN revolutionized broadcasting ten years ago,
IP networks will take them to the next level,” says Telos CEO and
founder Steve Church. “More and more, broadcasters rely not only on
content generated at local studios, but a mix of programming both local
and external. Zephyr iPort provides a simple, efficient way to share
multiple channels of low-delay, broadcast-quality audio between distant
facilities, using IP networks.”
Zephyr iPort is equipped with a Livewire™ interface; when
used as part of an IP-Audio network, iPort transports 8 channels of
stereo audio plus control between two Livewire-equipped sites over an IP
link. Connecting iPort to a Livewire network is easy: a single Ethernet
cable is all that’s required; no need for expensive converters,
interfaces or connectors. For standalone use outside a network, Zephyr
iPort can be paired with an Axia Audio AES/EBU or Analog Audio Node for
studio-quality audio I/O.
The technology in Zephyr iPort might just make it the
most user-friendly broadcast codec ever. Livewire networks continuously
“advertise” the presence of active audio sources, so the network knows
when sources are available; iPort takes advantage of this source
advertising so that whenever a codec connection is established, it
appears instantly on the network. All the board-op at the console needs
to do is assign the codec source to a fader, and audio automatically
flows both ways.
Zephyr iPort can also be used for any application where
MPEG encoding and/or decoding are needed for transmission over IP
channels, such as STL links, Internet streaming, satellite uplinks,
broadcasting to cell phones, and other audio distribution systems.
iPort’s efficient use of Livewire I/O combined with multiple codecs in a
single 2U device result in a low cost per channel compared to that of
multiple single-channel codecs.
Because not every remote connection is the same, Zephyr
iPort users have a comprehensive selection of connection protocols from
which to choose. There are standard MPEG Layer 2, Layer 3, AAC and
aacPlus choices, plus low-delay AAC-LD and high-efficiency low-delay
AAC-LD+HE, both with special error resilience protection that conceals
low levels of random packet loss. Zephyr iPort also includes AAC-HE+PS
(High Efficiency + Perceptual Stereo), the most bit-efficient codec
available today, allowing stereo operation down to 32kbps.
Zephyr iPort is perfect for facilities that already have
Axia IP-Audio networks, but using it with a directly connected Axia
Analog or AES Node offers a low-cost solution for any multi-channel MPEG
over IP application. Zephyr iPort features two Ethernet ports: one to
connect to the Livewire network, and another for connection to the WAN,
maintaining full isolation between the two networks for security
purposes.
Visitors to IBC 2007 can see Zephyr iPort at the Telos /
Omnia / Axia display in Stand #8.239. Zephyr iPort will begin shipping
3rd Quarter, 2007, with a manufacturer’s suggested retail price of
$5,495.00 USD.
