EQM 200 EDGE-QAM MODULATOR FAMILY
GENERAL
The EQM 200 is generating up to 24 encapsulated in UDP format. The Conversions of the MPEG transport
RF - QAM channels to add DVB-C payload of the UDP packets should stream like PCR restamping and
services into distribution networks be compliant to the DVB MPEG-2 "insertion of limited zero-packets"
at CATV-Headends or near the edge transport stream packets. These are supported. The modulator can
