Free software update for Zephyr iPort users

Free software update for Zephyr iPort users

2 February 2011, Cleveland Ohio, USA

Broadcasters with the Zephyr iPort MPEG Gateway can download the newly-released v1.5.2 software update from the Telos website, free of charge.

Zephyr iPort enables broadcasters to transport multiple channels of stereo audio across IP networks with guaranteed QoS, 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 2RU 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 AACLD+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 bitefficient 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.
