Product Description

MPEG4/MPEG2 hd wth 4 HDMI/SDI input and ASI RF output full 1080P encoder modulator

Overview

HPS852A 4 in 1 HDMI/SDI to DVB-C Encoder Modulator is HIPRO's new breakthrough all-in-one devices which integrate encoding (MPEG-2 HD/SD, MPEG-4/AVC H.264 HD/SD) and modulating to convert 4-channel HD/SD-SDI signals into DVB-C RF output. It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/SDI /CVBS…) as needed. In conclusion, its high integration and cost-effective design make this device widely used in variety of digital distribution systems such as digital CATV, satellite and terrestrial digital TV broadcasting, 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.
