4 Ch HD-SDI to QAM, ASI & IP HD Encoder RF Modulator
B-QAM-SDI-IP-4CH-LL series products are QuetTel’s new breakthrough all-in-one devices which integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulating to convert signals into DVB-C/DVB-T/ATSC-T/ISDB-T RF output. It has equipped with 4 HD-SDI channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP (4*SPTS) port.
It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (SDI/HDMI) as needed.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by TVs or STBs and etc.
With its various inputs available, our B-QAM-SDI-IP-4CH-LL series products are wildly used in public places such as the metro, market hall, theatre, hotels, resorts, and etc for advertising, monitoring, training and educating in company, schools, campuses, hospital… It’s a good choice to offer HD channels and more.
