TELOS | CODECS 28 Z/IP ONE THE IP CODEC THAT DROPS JAWS. (NOT AUDIO.) Broadband Internet is everywhere, which makes it ideal for live remotes. Unfortunately, public IP links are also notoriously er- ratic. You might be lucky enough to get a good connection… but even if you do, it might deteriorate during your broadcast. What to do? Cross your ingers and hope for the best? Or reduce your bit rate, sacriicing audio quality in hopes of making it through your show? With Z/IP ONE, the newest member of the Zephyr family, you don’t have to compromise audio quality for a solid connection. Z/IP ONE helps you get the best possible quality from public IP networks and mobile phone data services — even from connections behind NATs and irewalls. Telos collaborated with Fraunhofer (the developers of MP3) to develop a unique coding algorithm that adapts to changing In- ternet conditions on the ly, helping you maintain quality and stability. We call it ACT, short for Agile Connection Technology, and only Telos has it. Using ACT to sense and adapt to the con- dition of your IP link, Z/IP ONE delivers superb performance on real-world networks. It delivers reliable audio despite varying network conditions, and without the need to iddle with settings or codecs. Z/IP ONE adapts dynamically to minimize the effects of packet loss and jitter. When the bits are lowing smoothly, you’ll beneit FEATURES AT A GLANCE » Z/IP ONE is wireless capable and can connect to IP networks via Wi-Fi, EVDO, and UMTS. » Exclusive Agile Connection Technology (ACT) automatically senses network conditions and adapts codec performance to provide the best possible audio. » Largest choice of high-performance codecs: AAC-ELD, AAC-HE, AAC-LD, MPEG Layer-2, MPEG-4 AAC LC, MPEG-2 AAC LC, G.711, G.722 and linear PCM. » Dual IP ports for separate streaming and control. » Easy browser setup via built-in Web from the lowest possible delay and the highest possible idelity. But if congestion starts to occur, Z/IP ONE automatically low- ers bit rate and increases buffer length to keep audio lowing at maximum quality. Another way Z/IP ONE extracts excellent quality from even not- so-excellent IP connections lies in its use of a new codec based on low delay AAC: Advanced Audio Coding-Enhanced Low De- lay (AAC-ELD), which gives excellent idelity at low bitrates with nearly inaudible loss concealment and very little delay. (You have your choice of standard high-performance codecs too, including AAC-HE, AAC-LD, MPEG4 AAC-LC, MPEG2 AAC-LC, G.711, G.722 and even linear PCM.) Z/IP ONE’s front panel is friendly and simple to use. Naturally, there’s a built-in Webserver too, for remote control and easy coniguration using any Web browser. Our exclusive Z/IP Server service, free to Z/IP owners, lets you easily get around NATs and network irewalls for fast connections to your favorite locations. Around back, you’ll ind convenient XLR ins and outs, a Livewire port for IP-Audio, WAN jack for connection to “the outside world”, and even a parallel port for GPIO contact closures. All in a compact, 1RU package. Z/IP ONE. The convenience of the Internet — the sound of Telos. server. » Push mode for one-way network connectivity such as satellite broadcasts. » Multiple push mode, push to multiple destinations. » Sophisticated NAT traversal support. » Convenient directory server, no need to know another device’s IP address. » Transparent RS-232 channel for audio side channel or metadata, e.g., RDS. » 8-bit parallel GPIO port for signaling and control. » Slim 1RU form factor it is equally at home in a studio rack, remote kit or road case.
TECHTALK BLOG TELOSALLIANCE.COM/BLOG iPORT LIVEWIRE TO IP MPEG GATEWAY BROCHURES TELOS-SYSTEMS.COM/BROCHURE Talk about “high-density” equipment: the 2RU Telos iPort saves you money and rack space by housing eight stereo MPEG codecs in one small device. A pair of iPorts on each end of a QoS-controlled IP link can send and receive 8 channels of bi-directional stereo MPEG audio. Or, use iPort as a one-way “push” link to en- code and deliver 16 channels of broadcast-quality one-way audio to a remote destination. With its ability to send multiple MPEG channels over IP connections, iPort is perfect for audio transmission over VPNs, satellite links, Ethernet radio systems, and Telco or ISP-provided QoS- controlled IP services. You can use iPort for studio-to-transmit- ter links, network distribution systems, multi-channel links to remote studios. You can use a QoS-enabled IP link between two studios with Livewire networks, put an iPort at each end, and pass audio and GPIO between locations as if they were just next door. Paired with an appropriate server, you can even use iPort to generate multiple channels of MP3 or AAC for Internet streaming, broadcasting to mobile phones, and audio distribution systems… the possibilities are limited only by your imagination. iPort uses the Livewire AoIP standard for I/O. A single Ethernet cable is all that’s needed for all inputs, outputs, GPIO and remote control. Uncompressed 24-bit/48kHz audio goes in from your SOFTWARE UPDATES TELOS-SYSTEMS.COM/SOFTWARE network via Ethernet; compressed MPEG streams go out on the same cable — eliminating expensive, space-consuming convert- ers and connectors. Or, use the separate WAN connection to send your audio over an outside network. Not using Livewire yet? No problem – just pair the Telos iPort with an Axia analog or digital audio node to make a standalone high-density audio codec package. How do iPort streams sound? Fantastic. For years, Telos has had a tight working relationship with Fraunhofer IIS, the inventor of MP3 and co-inventor of AAC. The encoding algorithms inside iPort are genuine FhG, not some no-name knockoffs. A full range of state-of-the-art codec types and bitrates are supported; the highest-possible quality implementations, running on a powerful Intel loating-point processor. Choose AAC-LD for delay-sensitive applications, AAC-HE and AAC-HEv2 for low bitrate requirements, standard MPEG AAC for best quality and resilience to packet loss at higher bitrates, MP3 and MP2 for legacy applications. You’d expect all this to cost a lot, but it doesn’t: we built iPort on a single industrial motherboard, rather than the usual “multiple DSP cards in a frame” approach. Together with the Livewire- only audio interface, the iPort costs a fraction of legacy card- frame designs.
