HPS852A series products are new breakthrough all-in-one devices which integrate encoding (MPEG-2 HD/SD, MPEG-4/AVC H.264 HD/SD) and modulating to convert V/A signals into DVB-C RF output. It has equipped with 4 HDMI (4 SDI optional) channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP (4*SPTS) port.
Delay problem has been greatly reduced to achieve an extremely low value from the encoding progress to the decoding terminals. It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/SDI /…) 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 DVB-C TVs or STBs and etc.

Why do we need 4 x DVB-C carrier output in one device?
Firstly, it is to guarantee the sound picture quality of HD programs.
As we all know, to guarantee the picture quality of 1920x1080@50I/60I resolution HD program, the video bit-rate may exceed 10Mbps and even reach up to 15Mbps. However,
when the modulating constellation is 64QAM, the maximum possible bit-rate output for single DVB-C carrier is only around 20Mbps.
15Mbps x4 =60Mbps > 20Mbps.
It means the single DVB-C carrier simply can't carry the 4 channels 1080i HD program if the average bit-rate exceeds 10Mbps.
That's why we design 4*DVB-C carrier modulation board which quadruples the maximum possible bit-rate bandwidth up to 80Mbps and above when 64QAM constellation is used. This rightly makes it reliably carry 4 channels MPEG2 HD programs output simultaneously.
Below brief chart will help to more clearly illustrate the working principle.
Secondly, it is cost-saving.
Its high integration allows users to transmit more programs with fewer devices. It undoubtedly saves the cost for you and me.
