PRODUCT DESCRIPTION
The Distribution of Digital Television Signals from Digital Satellite Transmissions, QAM CATV systems, MPEG2 Transport Streams, or ATSC/VSB Broadcast Stations. 

A versatile line of digital headend products for the reception and redistribution of digital television signals for cable television and private cable headends. Featuring a flexible modular approach, this product line offers the ability to QAM modulate digital signals onto a cable system using MPEG2 transport streams, QPSK satellite signals, QAM CATV signals, or off-air ATSC/VSB transmissions. Off-air to cable ATSC/VSB to ATSC/VSB can also be accommodated.

Professional quality, modular, digital headend component designed to provide optimum performance for VSB or QAM demodulation. It can be used for demodulating signals from CATV systems or off-air antennas.
