Telos Systems will debut an addition to its Zephyr line of MPEG codecs for broadcast.
The Zephyr iPort MPEG Gateway transports up to eight channels of bi-directional stereo audio between locations using IP networks.
Zephyr iPort has a Livewire interface. When used as part of an IP-Audio network, it transports audio plus control between two Livewire-equipped sites over an IP link. Connecting iPort to a Livewire network requires an Ethernet cable. For standalone use outside a network, Zephyr iPort can be paired with an Axia Audio AES/EBU or Analog Audio Node for audio I/O.
Zephyr iPort also can be used for applications 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.
Users can select among connection protocols including MPEG Layer 2, Layer 3, AAC and aacPlus choices, plus low-delay AAC-LD and high-efficiency low-delay AAC-LD+HE, both with error resilience protection that conceals low levels of random packet loss. Zephyr iPort also includes AAC-HE+PS (High Efficiency + Perceptual Stereo), allowing stereo operation down to 32 kbps.
Telos/Omnia/Axia also has announced a lineup of a dozen presentations in its booth Monday through Wednesday, including several by users of its products.
Among those appearing will be Andy Hollins of BBC Radio; Matt Aaron, engineer of “The Dave Ramsey Show”; Chuck Ide of Clear Channel Los Angeles; Cris Alexander of Crawford Broadcasting; Charles Lelievre of Connoisseur Media; and Paul Donovan of CBS in Boston.
The schedule of booth speakers is at the Telos Web site.
