2Wcom MM01 - Audio over IP (AoIP) Codec - discontinued Replacement: IP-4c

Rock solid 1-channel audio over IP codec with SFN and Stream4Sure capability

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 2Wcom MM01 supports all currently established standards (AES67 – RAVENNA, Livewire+, SIP, SAP, PTP, RTSP / MPEG 1/2 Layer 1, 2, 3, AAC, E-aptX) and, depending on customer requirements, it can operate with very low delay, with additional redundancy or by multiplexing data into a DVB compliant MPEG transport stream. This great flexibility allows for maximum application flexibility regarding customer system requirements and project budget.

Additional key features include 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 is microsecond accurate latency control (e.g. for SFN – single frequency networks).

The new 2wcom Stream4Sure standard will provide an even higher reliability by sample precise seamless data selection for up to 4 source streams with different codecs. The latest implementation of SIP, SAP, PTP and RTSP enhanced the features of the 2Wcom MM01 to provide a Ravenna ready device for the use in a broad variety of ways.

All of these features conform to existing standards to ensure a professional integration into a customers system.
