TRANSCAST Satellite Modulator DVB-S2 MPEG4
Lebih Lengkap Mengenai TRANSCAST Satellite Modulator DVB-S2 MPEG4
Description :
TRANSCAST Satellite Modulator MOD DVB-S2 Modulator is a high-performance modulator developed according to DVB-S2 standard which is the standard of second generation of the European broadband satellite telecommunication. It is to convert the input ASI and IP signals alternatively into digital DVB-S/S2 RF output.
BISS scrambling mode is inserted to this DVB-S2 modulator, which helps to safely distribute your programs. It is easy to reach local and remote control with NMS software and LCD in the front panel.
With its high cost-effective design, TRANSCAST MOD DVB-S2 modulator is wildly used for broadcasting, interactive services, news gathering and other broadband satellite applications.
Features :
l Fully complying with DVB-S2 and DVB-S standard
l 4 ASI inputs supporting hot backup (3 for backup)
l Support IP (100M) signal input
l QPSK, 8PSK, 16APSK, 32APSK Constellations
l Support RF CID setting
l Constant temperature crystal oscillator, as high as 0.1ppm stability
l Support coupling 10Mhz clock output through RF output port
l Support 24V power output through RF output port
l Support BISS scrambling
l Support local and remote control with SNMP or Web-server NMS
l Support SFN TS (with MIP or IIP) transmission
l Output frequency range: 950~2150MHz, 10KHz stepping
