Detailed Product Description

DTMB SFN Adaptor DMB -1100 inserts Megaframe Initialization Packet into MPEG-2 TS periodically, controls all the transmitters in SFN network to emit the same signal bits at the same time. This DMB -1100 has 2 MPEG input and output, which can be setup into 2 adaptors independently, also can be setup into redundant mode. TPS supports all the GB20600-2006 mode and can adjust the MPEG TS bit rate automatically. It is the key equipment in construction of the SFN network.

Main features

• Support all the GB20600-2006
• Output bit rate can be adjusted automatically according to the transmission mode
• Redundant input with automatically switching and bit rate adaptation   
• RS Code, PCR correction
• Web browser remote control, SNMP is optional
