HPS381 is newly developed Encoder & Modulator which integrates MPEG2 HD/MPEG4 HD video encoding and ISDB -T (DVB-C/-T/ATSC Optional) modulation to convert HDMI signals to ISDB-T RF out in the frequency range of 30~960MHz. It has equipped with 1 channel of HDMI input, 1 ASI input, and output with 2 ASI ports, 1 UDP IP port, and 1 RF port.
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 ISDB-T standard TV sets, ISDB-T STBs and etc.
The device can be wildly used in public places such as metro, market hall, theatre, hotel, resort, 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.
