2wcom introduces a new transport solution that combines HD Radio® E2X and analog or digital MPX into one synchronized stream. The result is precise HD/FM timing, simplified distribution, and improved reliability across IP networks.
In hybrid radio, timing matters.
To keep HD Radio® and FM properly aligned, both parts of the signal chain need to stay in sync throughout transport and distribution. As broadcast infrastructures continue to move toward IP-based workflows, that challenge becomes more important and more complex.
2wcom’s new solution addresses this by combining the HD Radio® E2X signal and an analog or digital MPX signal into one synchronized transport stream. Instead of managing separate paths for HD and FM, broadcasters can transport both together in lockstep.
This brings clear practical advantages. It helps maintain precise HD/FM timing, simplifies hybrid radio distribution, and improves reliability across IP networks. At the same time, the solution is designed to fit into existing infrastructures, with compatibility for Gen3 environments and support for analog or digital MPX workflows.
The new transport solution also supports flexible MPX transport options. Broadcasters can work with uncompressed MPX in the range of 1.5 to 6.1 Mbit/s or use compressed MPX at 320 kbit/s with aptMPX or µMPX, depending on network requirements. High-precision timing via GPS / 1PPS ensures alignment between HD and FM, while the stated FM accuracy is suitable for SFN operation.
For modern IP-based distribution, resilience is another key benefit. According to the product text, E2X can be protected with mechanisms such as SRT, Dual Flow redundancy, and other resilient transport technologies, supporting reliable delivery across real-world networks.
By transporting HD Radio® E2X and MPX together in one synchronized stream, 2wcom offers broadcasters a robust and future-ready approach to hybrid radio distribution: reliable, compatible, and synchronized.
