Product overview

KBT3542-4 is a low bit rate encoding, DVB-T modulation integrated device to convert four channels A/V signals to DVB-T RF out in the frequency range of 30~960MHz. It has equipped with 4 channels CVBS input in two individual modules, 1 ASI input and 1 RF input.

The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. its output signal is to be received by a DVB-T standard TV, DVB-T STB.

The device can be used in public place such as metro, market hall, theatre, hotels, resorts, etc for advertising. It also can be used for monitoring, training and educating in company, schools, campuses, hospital… besides that it’s a good choice for bars to offer HD sports channels, for VIP entertainment channels, and more.
