Detailed Product Description

DVB-T SFN Adaptor (MIP Inserter) DMB-1018  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 usage and can be setup into the hot-swap mode. The adaptor can configure MPEG TS output bit rate according to TPS. The DMB-1018 DVB-T SFN Adaptor is the key equipment in the construction of the DVB-T/H 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
