Demodulators

Scale Services and Expand Bandwidth

NTSC Demodulators from Scientific Atlanta, a Cisco company, enable cable North American operators to insert 8VSB television signals including off-air standard definition, off-air HDTV, CATV and IF into digital cable systems. Options include a built-in multiplexer, which allows operators to save space and money by combining two 8VSB broadcast signals into a single 38 Mbps ASI output for use in 256 QAM cable applications. Products in this series even offer the ability to selectively insert specific elements of a given stream into the system. For example, say a stream contains both SD and HD signals; you could choose to insert only the HD or only the SD transmission. Setup and quality monitoring are easy, requiring little more than a standard web browser.
