DMB-1018 DVB-T SFN Adaptor or called SFN MIP Inserter inserts Megaframe Initialization Packet(MIP) into MPEG-2 TS periodically, controls all the transmitters in SFN network to emit the same signal bits at the same time. This adaptor has 2 MPEG TS input and output, it can be setup into 2 standalone adaptors for using and can be setup into the hot-swap mode. The adaptor can configure MPEG TS output bit rate according to TPS. The DVB-T SFN MIP Inserter( SFN Adaptor) is the key equipment in the construction of the DTTB SFN network.

Main features:
MIP Insertion comply to TS 10191
All DVB-T& DVB-H modes supported, including hierarchical modes
5,6,7,8 MHz bandwidth supported
Powerful ASI input management
Duplicated ASI outputs when operating in non hierarchical mode
Double flow(HP & LP)MIP Insertion in hierarchical mode
Web browser remote control, SNMP is optional
