An apparatus and a method of providing internet broadcasting service by using multicast address learning bridge are provided to change the channel of subscribers in real time by rapidly performing a channel change requested by the subscribers. A method of providing internet broadcasting service by using multicast address learning bridge includes the steps of: generating an Ethernet channel address of predetermined multicast type corresponding to a broadcasting channel which is requested; receiving a channel request frame of which a source address is the Ethernet channel address and a destination address is a broadcasting server address which provides a broadcasting data stream; extracting the source address and the destination address from the channel request frame; confirming the extract source address whether to contain in a selected address entry; confirming whether a port includes in an allowed port entry or not; and confirming whether the extracted source address includes in the multicast forwarding address entry or not. A subscriber network for providing an Internet broadcasting severe to a subscriber consists of a plurality of receiving terminals(100,105,110,115), an IP-TV set top box(120-1, 120-2, 120-3, 120-4) which connects the receiving terminals to each access device(160), a concentration device(150) which concentrates a plurality access devices(160), a connection sever(140) and a broadcasting sever. |
