HPS381 HDMI to ISDB-T modulator with MPEG2 MPEG4 Video Encoding

Product Overview

HPS381 is Catcast's 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 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 setsISD B-T STBS and etc.

The device can be  wildly  used in public place 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.
