Part of the SIP Opus Codec.
The M400 SIP Opus Stereo Encoder/Decoder is Barix second model in its SIP Opus Codec family of audio over IP transport solutions. Barix says the unit combines the simplicity and versatility of SIP-based link negotiation with the quality and efficiency of the Opus compression format. It is for IP audio delivery for studio-to-transmitter (STL), studio-to-studio (SSL) and remote contribution applications.
The unit features the open standard, royalty-free Opus audio compression format, which has gained significant popularity for its audio quality, bitrate efficiency and low latency. The hardware device combines the advantages of Opus with SIP functionality to dynamically establish seamless links across SIP-compatible telephone, radio or other communications systems, enabling the codecs to ‘dial’ other SIP devices or phone numbers and automatically negotiate a transmission link for audio streaming.
“SIP-based link establishment has proven to be very compelling for broadcasters as they transition their STL and remote contribution operations away from expensive and end-of-life ISDN services,” said Reto Brader, Barix CEO. “Our SIP Opus Codec family augments the benefits of SIP with the bandwidth efficiency and stellar quality of the Opus codec, and in typical Barix fashion, makes it all very cost effective. Our initial MA400 model has been deployed successfully by broadcasters from small stations to major media groups, and we’re excited to add this to our portfolio so customers can choose exactly the right configuration for their needs.”
Leveraging SIP-based connectivity enables broadcasters and producers to move away from the common legacy approach of using costly and technologically outdated ISDN circuits. For remote contribution from the field, SIP enables dynamic link establishment by ‘dialing’ registered SIP endpoints without the need for static, public IP addresses. The elimination of public IP addresses brings similar benefits to STL and SSL applications while further increasing security.
