Microyal Model MDH-3000P
DVB CI Demodulators and Decoders Series

 DVB CI Demodulators & Decoders including:
  1. MDH-3000P-30S Professional DVB-S QPSK
    Digital CI Decoder
  2. MDH-3000P-30C Professional DVB-C QAM
    Digital CI Decoder
  3. MDH-3000P-30T Professional DVB-T COFDM
    Digital CI Decoder

Features:

  • Fully comply with DVB-S and MPEG-2 standards
  • Common Interface with 2 slots (PCMCIA) taht can support the encrypted systems of Conax, CryptoWorks, Irdeto, Mediaguard, Nagravision, SECA, NDS, and Viaccess.
  • Switchable between the two slots of PCMCIA to output analog Video/Audio signal.
  • Two signal input options, one is QPSK which receives DVB-S signal from satellite, the other is ASI which could come from another digital CATV headend instrument (ex. another MDH-3000P).
  • One ASI input amd twp ASI outputs, the un-decrypted programs could loop through to another MDH-3000P for further decrypting.
  • BNC CVBS video and balance stereo audio XRL are available on the rear panel
  • Transparent decryption ASI output or non-decryption output switch.
  • LED display, function touch button on front panel, user friendly operation interface
  • Auto network or transponder search function and code stream information update
  • Store up to 2000 channels
  • Video PID and Audio PID setup
  • Automatic reserved channel after being moved
  • Support OSD teletext (DVB ETS 300 706) and caption function
  • 256 color screen display, support multi-languages such as English, French, German, Spanish, Italian, Chinese, Arabic, etc.
  • EPG function, support PIG (Picture in Graphics) display
  • Automatic PAL to NTSC conversion and vice-versa
  • Software upgrade via RS-232 interface (PC to MDH-3000P or MDH-3000P to MDH-3000P)
