IP to RF Modulator optional DVB-C/DVB-T/ISDB-T/ATSC/DTMB
Q4 IP to RF modulator, with ASI input and output, optional modulation (DVB-C, DVB-T, ATSC, ISDB-T, DTMB) to convert Video/Audio signals into RF over exist Coax Cable distribution. It provides a best-of-class modulator platform for Digital TV Owners and IPTV operators.
The platform can change the modulation signal by software upgrade, this flexible operation can help to reduce the cost in the operation of the project. Q4 supports modulation channel independent multiplexing, with DVB-T, ISDB-T, DVB-C, ATSC, DTMB modulation output, and each module can output different modulation signals.
By using PSI/SI technology, inserting NIT information table in WEB, Q4 series increased compatibility with terminal products in cable TV application.
This is an ideal solution used largely to Hotel, entertainment facilities, education broadcasting systems at schools and government buildings or IP Source signals convert to Cable TV broadcast environments.
High density, high quality, high performance, high flexibility
