Comrex BRIC-Link II Stereo BRIC IP Codec.


The Comrex BRIC-Link II, like the Comrex BRIC-Link, is a low-cost, high-performance solution for audio-to-IP conversion. Leveraging many of the core technical aspects of Comrex’s successful remote broadcast ACCESS product line, BRIC-Link II provides for an elegant way of moving linear or compressed audio with very low delay. BRIC-Link II is very simple to use, and can be deployed over a wide range of IP links. While it carries an entry-level cost, BRIC-Link II maintains superb audio specifications and hardware reliability, making the system suitable for STLs and other mission-critical functions without the expense required of more full-featured codecs. BRIC-Link II is contained in a small desktop package. Two BRIC-Link IIs may be installed to occupy 1U of rack space.

Applications Like its predecessor, BRIC-Link II is uniquely suited to point-to-point “nailed up” highquality audio links over a variety of data networks, like ISM band IP radios, T1/ E1s, satellite channels, WANs, and LANs. The robustness of the BRIC technology (Broadcast Reliable Internet Codec) used in the box allows the system to perform well on the public Internet as well (using AAC compression modes). BRIC-Link II is capable of “multistreaming” – BRIC-Link II has the ability to run one encoder per box, but this single encoder stream may be sent to up to three destinations simultaneously. Additionally, BRIC-Link II can act as a streaming server, delivering AAC and HE-AAC to compatible PC-based media players.

Audio Coding For users concerned about delay and coding artifacts, BRIC-Link II offers a robust stereo or mono linear mode that does not compress audio. In addition, BRIC-Link II is the only real-time audio codec to offer FLAC lossless compression, which reduces network throughput by 30– 40% with absolutely transparent coding and no tandem coding concerns. For situations where more reduced bandwidth is desired, BRIC-Link II offers AAC/HE-AAC modes as standard, allowing superb audio quality at dramatically reduced data rates. For compatibility with mobile phone and web apps, BRIC-Link II also implements Opus audio compression, along with VoIP standards G.722 and G.711.
