MDH-3000P/-C/-T professional
digital CI decoder (with 2 ASI TS input/output, factory optional QAM or
COFDM Input) supports Common Interface systems, user may insert up to two
PCMCIA CI modules to receive various encrypted DVB-S/-C/-T or DVB-ASI
programs, including Conax, CryptoWorks, Irdeto, NDS, Mediaguard, SECA,
Nagravision and Viaccess. It provides two signal input options, one is QPSK/QAM/COFDM
which receiving DVB-S/-C/-T signal from, the other is ASI which could come
from another digital CATV headend instrument (for example, another
MDH-3000P/-C/-T). The input encrypted satellite or ASI signal can be
decrypted to free TS stream signal and remultiplex into the same TS stream,
then output with its ASI interface. Because of one ASI input and two ASI
outputs, the un-decrypted programs could loop through to another
MDH-3000P/-C/-T for further decrypting. Programs in an encrypted
carrier/transponder can be all decrypted with a daisy chain of multiple
MDH-3000P/-C/-Ts. In addition, MDH-3000P/C/-T can output analogue video and
audio signals, BNC CVBS video and balance stereo audio are available on the
rear panel. RS-232 interface realizes remote monitoring and software
upgrade. It supports both burst mode and byte mode TS input. MDH-3000P is
best for professional systems such as CATV headend signal sources, DVB-S
signal decryption and monitoring. Microyal's MDH-3000P is 19" by 1U rack
mountable with touch button interfaces on the front panel. It is your best
choice of professional CI decoder with ASI transport stream input and
outputs for your analogue and digital CATV headend applications. The input
signal of DVB-T comes from air, the input signal of DVB-C comes from CATV
network or CATV headend. |
