MM01 - Audio over IP (AoIP) Codec
Professional multi-format Duplex AoIP (Audio over IP) Coder/Decoder
Professional Audio over IP (AoIP) distribution for STL (studio to transmitter lines) or studio to studio transmission has been established within the broadcast market in the last couple of years and is developed further at a steady pace. Former weak points such as signal runtime, synchronization and reliability finally belong to the past due to highly sophisticated transmission mechanisms using IP protocols and very finely tuned forward error corrections (FEC) that now make common IP networks suitable for professional broadcasting of audio signals.
The MM01 supports all currently established standards and, depending on customers requirements, it can operate with very low delay, with additional redundancy or based on a DVB transport stream. This great flexibility allows for maximum action flexibility regarding customers system defaults and project budget.
Additional key features are Stream4Sure seamless switching, first class multiformat audio coding, rock solid network connection and IP robustness, even in stress conditions, thanks to 2wcoms “dual streaming” mechanism (= redundant contribution of IP packets by different transmission paths). Another highlight of the further development is microsecond accurate latency control (e.g. for SFN – single frequency networks).
All these features conform to existing standards to ensure a professional integration into a customers system
Supported Standards: EBU Tech 3326, Ravenna, Livewire (Axia), Precision Time Protocol (PTP), Session Announcement Protocol, Session Initiation Protocol (SIP), Session Description Protocol (SDP)
