Abstract: A method for an apparatus for transceiving IP based bidirectional advertisement are provided to enable a user to see, shop and buy advertisement and information the user wants. An IP-based bidirectional advertisement server(210) comprises a setting unit(211), an advertisement holder(212), a multicast transmitting unit(213), a unicast transmitting unit(214) and a detailed advertisement transmitting unit(215). The setting unit sets up a bidirectional advertisement receiving mode by a user. In this case, the setting is possible by referring to whether a network system to which the user belongs supports multicast. When the bidirectional advertisement receiving mode of a user A is set up as the multicast mode, a multicast group address according to the setting is assigned. And when the bidirectional advertisement receiving mode of the user A is set up as a unicast mode, the IP address of a server requesting the bidirectional advertisement is informed to the user.
