AEQ Phoenix Stratos
This double, full-duplex codec complemens the IP link with one X21/V35 and one ISDN interface. The Stratos comes with the same features for IP as the Phoenix Venus, but adds the multiple telecom interfaces making it ideal to transition from ISDN to IP. The codec provides for automatic backup or fail-over features ensuring that live communications are uninterrupted in the event of main link-failure. The unit can be operated from the front panel but can also be managed from the ControlPHOENIX software. The Stratos has been developed to allow for additional and optional encoding algorithms upon request, such as AAC and OPUS.
Comrex Access 2USB
This IP audio codec uses BRIC technology, a sophisticated suite of tools that allow for high-quality, low-latency, stable transmission of audio over a wide variety of data networks. Intelligent, dynamic jitter buffer management, BRIC algorithms and the SwitchBoard Traversal Server all work together to provide the most stable audio-over-IP transmission platform available for remote broadcast. Access 2USB offers several ways to connect: The included USB Wi-Fi modem, integrated Ethernet port, or either one of two USB ports to connect to 3G/4G cellular data networks. The unit also includes a USB POTS/PSTN modem to connect to legacy POTS Lines.
Harris Intraplex IP Link
The Intraplex IP Link family of IP audio codecs offers an array of audio coding options for use in studio-to-transmitter links (STLs) as well as audio contribution and distribution networks. Support for IP multicast and multiple unicast streams enable one encoder to feed multiple decoders. By incorporating three IP interfaces for streaming and management, the IP Link systems provide reliability unmatched in comparably priced codecs. Additional features include N+1 hardware redundancy with automatic synchronization of configuration, optional hot-standby power supply, dynamic stream splicing, multicoding, automatic backup options, and an easy-to-configure and operate Web browser interface.
Moseley Rincon delivers multi-channel audio via various transport networks simultaneously while using multiple algorithms. As a standalone STL, Rincon uses IP MPLS, private and public networks. Used as the audio engine for a Starlink 950 or Event licensed 11 or18GHz radio links Rincon becomes an eight-channel digital STL. Rincon works in a number of station topologies, point-to-point unidirectional, point-to-point bidirectional and point-to-multipoint multicast. Audio transmission formats include linear uncompressed, AAC LC and LD, MPEG Layer 2, and MP3. Up to four stereo pairs can be sent in either direction on the link. The unit is controlled by a browser, SNMP or a smartphone.
Telos Z/IP One
Telos Z/IP One uses public IP links for transmission of program-quality remote audio. With its wide range of genuine MPEG and AAC codecs and flexible connection via SIP, N/ACIP, and Telos’ own TSCP protocol, the Z/IP One makes IP remotes easier. Latest updates include Symmetric RTP connectivity, which simplifies IP remotes by sending a high-quality IFB feed from studio to field using the same firewall port employed for the initial connection, and support for Luci Live smartphone and tablet apps, allowing reporters to originate high-quality HD Voice remotes using any Apple or Android portable device with a Wi-fi, 3G, or 4G connection.
Tieline Genie Distribution
Designed for multipoint audio distribution, this codec provides six channels point-to-point, three independent bidirectional stereo or six independent bidirectional mono connections, multicasting, multi-unicasting and more. Genie Distribution is IPv4/v6 ready and includes dual Gigabit LAN ports, dual internal power supplies, and 24-bit/96kHz audio sampling. It has professional algorithms including Apt-X Enhanced, AAC, Opus and many more. Genie Distribution features network management tools, plus Tieline’s SmartStream Plus dual redundant IP streaming software for STL-grade reliability over networks like the Internet. A WheatNet-IP version is also available.
Worldcast Systems APT Horizon NextGen
The APT Horizon NextGen includes SureStream technology, which offers broadcasters the possibility of T1-like quality and reliability using cost-effective IP links with always-on redundancy. The codec hardware is built on a DSP-based platform with dual IP ports and redundant power supplies. The unit supports a full range of algorithms including Enhanced Apt-x, MPEG Layer II, MPEG 4 AAC-LC, -LD, -ELD, and HE-AAC and HE-AACv2 as well as linear audio. It includes Dynamic DNS and NAT traversal mode and IP packet forwarding. Using open Internet connections and multiple unicast, the system can send audio to 12 decoders with SureStream and up to 24 decoders without.
