RF R-PHY Video Engines
-
ATX’s RF R-PHY video engines provide a mux pass-through function that enables cable operators to maintain existing video encryption functionality on in-service edge QAMs, alleviating the need to migrate encryption functionality to the CCAP video core during early stages of DAA transition. ATX RF R-PHY video engines also relieve MSOs of undertaking back-office system integration to reconfigure and manage muxes and broadcast lineups in CCAP video cores. For MSOs considering an accelerated transition to IPTV, the ATX RF R-PHY Video Engine provides a low-cost and low-complexity alternative to implementing a CCAP video core.
