Abstract :
Previously, mini-fiber-node (mFN) technology has been proposed to upgrade existing cable TV (CATV) systems to provide bidirectional, broadband capabilities. In this letter, we describe how the mFN´s can be used to provide multiple channels of compressed digital video. This allows cable operators to simultaneously add additional broadcast and narrowcast digital video services and install bidirectional services cost effectively, without affecting existing services.
