METHOD OF INTERMEDIATING MULTICASTING SIGNAL FOR MULTICASTING EMBODIMENT

The invention relates to a multicasting relay method to secure a significantly increased number of simultaneous multicasting connectors under an identical network environment (B-RAS, NAS or the like) with no addition of service device under a modem environment utilizing xDSL and PSTN and a recording medium readably by a computer recorded with programs, the method comprising the steps of: prompting a contents providing server to induce the first xDSL connector terminal to an xDSL server (B-RAS) (step 1); broadcasting a multicasting broadcasting data to the xDSL connector server in real time (step 2); discriminating whether a relevant xDSL ser§ice device supports the multicasting (step 3); broadcasting the multicasting broadcasting data to the first xDSL connector terminal in real time and prompting the xDSL service device to receive the broadcasting data at a multicasting address (step 4); and relaying multicasting data to the second xDSL connector terminal from the xDSL service device of the relevant xDSL server (step 5).
