Introduction

TL400 series SFN Adaptor is developed independently by Beijing CircLoop Digital Image Tech. Co., Ltd., it can periodically generate and insert SIP into the MPEG TS, thus synchronizes signals transmitted by all transmitter in terrestrial DTV SFN. TPS supports all GB20600-2006 modes and can adjust the TS output bit-rate automatically; it is indispensable equipment to construct terrestrial DTV SFN.   
    From ASI to E1x4 and DS3/E3 network transmission adaptors are available, support SFN signal transmission on telecommunication equipment of microwave and SDH and so on, It is convenience to construct SFN, It can be used together with our TL300 network adaptorIP600 IR600 etc to design multi types SFN signal transmission scheme.

This equipment also can be used as network adaptor of ASI to E1XN or DS3/E3.

This equipment has abundant input and output interface: two ASI input (main and standby input can switch automatically), two ASI output interface, support SFN SIP inserting. With GPS clock input interface, one 10MHz input interface, one 1pps input interface. As well it has E1xN input interface (N=1,2,,3,4)2 channel DS3 output interfaces.

It is modular structure, based on web brows management, and easy to operate maintain.

Main Features

Main Function

• Fully conform to MPEG-2/DVB standard
• Support all GB20600-2006 modes,the output speed can adjust according to transmission mode automatically.
