Provides a cost effective and highly reliable solution for setting up a Single Frequency Network (SFN).

Frequency allocation is one of the main issue broadcasters and Network Operators have to face. NN6-MIP DVB enables spectrum band optimization by synchronizing the transmission of any transmitter within one SFN cell.

Description

Besides MIP insertion, NN6-MIP DVB possibilities are further enhanced thanks to the full implementation of DVB optional functions: any transmitter can be addressed individually, enabling time offset, and/or frequency offset … thus refining RF coverage.

A single de-synchronization or wrong SFN signaling can disturb transmission and cause a complete black-out. To prevent any SFN error, NN6-MIP DVB provides 1+1 redundancy mechanism through its patented technology SFNguard and enables SFN seamless switch-over.
