SQC 6100
Terrestrial Receiver for DVB-T
The SQC 6100 is a Digital Terrestrial Receiver De-
vice which is fully compliant with the standard
DVB-T (ETSI 300 744) standard for terrestrial
transmission systems.
The SQC 6100 integrates all analog and digital
data processing functions from the second inter-
mediate frequency input to the transport stream
output.
