Product Description
4*HDMI MPEG4 Encoder DVB-T Moulator
4*HDMI Encoder to DVB-T Modulator

Product Overview

HPS842A series products are Hipro's new breakthrough all-in-one devices which integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulation (DVB-C, DVB-T, ISDB-T, or ATSC) to convert V/A signals into RF output. It has equipped with 4 HDMI channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP port.
It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/CVBS/SDI/YPbPr/) 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, STB and etc with corresponding standard.
With its various inputs available, our HPS842A series products are wildly used in public places such as 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.

Why do we need 2 x DVB-T carrier output in one device?
As we all know, to guarantee the picture quality of 1920x1080@50I/60I resolution HD program, the video bit-rate may exceed 10Mbps, even up to 15Mbps. However, the maximum possible bit-rate output for single DVB-T carrier is only around 30Mbps.
15Mbps x4 =60Mbps > 30Mbps.
It means the single DVB-T carrier simply can't carry the 4 channels 1080i HD programs if the average bit-rate reaches 15Mbps.
That's why we design 2*DVB-T carrier modulation board which double the maximum possible bit-rate bandwidth up to 60Mbps, which rightly makes it reliably carry 4 channels HD programs output simultaneously.
Below brief chart will help to more clearly illustrate the working principle.
