Digital CATV

The Digital Collection offers a comprehensive series of products designed to multiplex, modulate, demodulate, process, and transcode signals in ASI, QAM, 8VSB, QPSK, and 8PSK formats.

The Headend is the heart of Cable TV system (whether the signals are analog or digital). It handles many functions including reception and processing of broadcast or "off-air" television signals and reception, decryption and modulation of satellite delivered programming in preparation for distribution to cable television subscribers.

The broadcast signals routed to the headend are filtered to reject any unwanted signals from adjacent off-air channels and adjusted for proper aural & visual carrier levels in. They can be fed to a signal processor or a demodulator / modulator approach can also be used.
