Техническая Спецификация для Cisco Model D-PCG1000 PowerKEY CAS Gateway

 

 

 

The Model D9479 Gigabit QAM Modulator (GQAM) 
represents an innovation in video transmission 
technology. The GQAM contains five input ports 
including four digital video broadcasting (DVB) 
standard asynchronous serial interface (ASI) inputs 
and a Gigabit Ethernet (GbE) port. 

The GQAM contains the core functionality of four of our Model D9477 MQAM Modulators. 
One GQAM frees up a total of seven additional rack unit (RU) openings, thereby making 
the GQAM an exceptional product for mass deployment of video-on-demand (VOD), 
anything-On-Demand (xOD), and other interactive broadcast services. 

The four ASI inputs allow for direct connection to current generation video servers, 
encoders, integrated receiver-decoders (IRDs), and other digital video sources at the 
headend. The GbE interface allows for connection to the next generation of video 
servers, either linked locally with the GQAM or remotely through a network. 

•  Contains the core functionality of the MQAM modulator 
•  Includes 5 input ports and can provide up to 16 QAM outputs to achieve the 

broadcast capacity of 4 MQAM modulators or 16 QAM modulators 

•  Enables direct connect to both DVB ASI and Gigabit Ethernet video sources at the 

same time and the capacity to create transport streams from any combination of the 
5 inputs 

•  Provides 4 DVB ASI inputs (216 Mbps each) and 1 plug-in Gigabit Ethernet input 

(GBIC) to multiplex content from any input to any of the 16 outputs (channels) 

•  Uses an output center frequency range of 91 MHz to 867 MHz 
• Incorporates

 DES and DVB Common Scrambling Algorithm options 

•  Enables higher rack density to save space 
•  Optimizes system management with provisioning and monitoring by the DNCS 
•  Facilitates deployment in either a headend or a hub
