Zusammenfassung:	PURPOSE: A digital multicast system is provided to simultaneously distribute multimedia video/audio programs to plural places through a digital network including subscriber lines from a single source known as a head end. CONSTITUTION: An MVP(Multicast Video Portal)(100) is connected to an IP core network(324), and is provided to an IP network(320) communicating with a CAG(Conditional Access Gateway)(420). Each subscriber communicates with the MVP(100) via the IP network(320) by using a remote control unit(335) of a self digital decoder(334). The MVP(100) is indirectly connected to the CAG(420). The MVP(100) transmits a modified program guide page to a TV set(336) through a browser of the digital decoder(334).
