Telos Systems, the originators of MPEG codecs for broadcast, will
unveil a dramatically new addition to its Zephyr family at NAB 2007: 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
going to 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
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,” remarks Rolf Taylor, Telos’
Telephony Product Manager. “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
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 NAB 2007 can see Zephyr iPort at the Telos / Omnia / Axia
display in Booth N7726. For more information about Zephyr iPort, contact
