    • An interactive advertisement system and a method thereof are provided. The interactive advertisement system includes an advertiser server, a local advertisement server, and a service receiver. The advertiser server requests registration of advertisement information by setting advertisement ID including target service areas and provides services in response to an order of available services corresponding to the advertisement information. The local advertisement server stores and registers the advertisement information including the advertisement ID corresponding to the registration request of the advertiser server, multicasts the registered advertisement information with the advertisement ID through an IP network, and transmits information related to a service request to the advertiser server. The service receiver extracts advertisement information providing a corresponding service from the received advertisement information, outputs the extracted information through a user interface, requesting the local advertisement server to order the input service, and receives the corresponding service from the advertiser server.

    • Provided is a method of transmitting and receiving a two-way advertisement. The method is performed separately from a broadcasting being received by a client. When the client calls for the two-way advertisement, an Internet Protocol (IP)-based two-way advertisement receiving apparatus of the client requests and receives the two-way advertisement from an IP-based two-way advertisement server; stores the two-way advertisement in an advertisement storage unit, wherein the two-way advertisement is transmitted from the IP-based two-way advertisement server which refers to an advertisement area code included in the two-way advertisement and transmits the two-way advertisement by using a multicast group address corresponding to the advertisement area code; and displays the two-way advertisement on a screen of a client using terminal of the client. In the case where the client receives a summary advertisement and desires to obtain more detailed information, the client can receive a detailed advertisement and order a product via the screen.
    • 提供了一种发送和接收双向广告的方法。 该方法与客户端正在接收的广播分开执行。 当客户端要求双向广告时,客户端基于互联网协议(IP)的双向广告接收设备从基于IP的双向广告服务器请求并接收双向广告; 在广告存储单元中存储双向广告,其中从基于IP的双向广告服务器发送双向广告,该广告服务器参考包括在双向广告中的广告区域代码,并且传送双向广告 通过使用与广告区域代码相对应的多播组地址进行广告; 并使用客户端的终端在客户端的屏幕上显示双向广告。 在客户端接收到摘要广告并希望获得更详细信息的情况下,客户端可以通过屏幕接收详细的广告并订购产品。
