2wcom has enhanced its FlexNsert range of radio distribution inserters to provide a precise solution for SFN FM network operators. Together with 2wcom’s receiver/decoders, the FlexNsert technology locks the timing of the FM signal to synchronize all cells in the network.

FlexNsert+ distribution inserter can be used as a timestamp generator, inserting the timing information into the MPEG stream. At the transmitter, the FlexDSR02/04+ DVB satellite receiver analyzes signals and ensures the timing of the FM transmission. Distribution can be by ASI, E1, IP or satellite and any one of the feeds can be selected for backup purposes.

The solution enables broadcasters to implement FM SFN networks using existing analog FM technology, with just one inserter for the uplink and a receiver/decoder at each transmitter. FlexNsert delivers microsecond accurate synchronization of FM cells, with automatic adjustment of runtime differences caused by variable packet delays, jitter and satellite anomalies.

The FlexDSR02+ and FlexDSR04+ digital satellite receivers offer a comprehensive feature set, with support for all major audio formats, automatic program switching, full regionalization capabilities, SIRC remote control through satellite, fail-safe dedicated hardware and more.
