Abstract: An IP-based two-way advertising system is provided. In particular, an IP-based advertising service server system and a digital television broadcast receiving system which interacts with the IP-based advertising service server system are provided. An advertisement in which a selection criterion value set by an advertiser for advertisement output is identical to a subscriber side selection criterion value is selected and transmitted to a subscriber terminal. Advertisement associated information transmitted to the subscriber terminal includes information for accessing a primary advertisement (172) for intuitively expressing minimal information about a product and information for accessing a secondary advertisement (173) for expressing detail information. The primary advertisement (172) and the secondary advertisement (173) are output according to selection of a subscriber. Therefore, an advertising service can be provided regardless of different broadcasting middleware standards which depend on the broadcasting system, such as IPTV broadcasting, satellite broadcasting and digital cable broadcasting. Also, since an advertiser (1 10) can register an advertisement by himself/herself without help of an advertising agency which produces an advertisement and includes the produced advertisement in a broadcast program, the self-employed can place an advertisement on television at a low cost.
