CUSTOMIZED ADVERTISEMENT SERVICE SYSTEM AND ITS METHOD BASED ON OPEN INTERFACE

摘要

A system and a method for providing a customized AD(ADvertisement) service system based on an open interface are provided to offer an efficient AD service by combining AD contents customized to each location/user characteristic and main contents with the open interface capable of receiving various CPs(Content Provider). A contents information obtainer(208) obtains information of main contents by requesting the information of the main contents to an open service gateway(105) in response to a contents request of a user terminal(101). A personal profile manager(209) stores and provides personal profile information. A personal EPG(Electronic Program Guide) provider(210) generates and transmits personal EPG information to the user terminal by using the main contents information based on the personal profile information. An AD requestor(211) transmits an AD contents request corresponding to a contents requestor to the open service gateway based on the personal profile information. The open service gateway includes an open API(Application Program Interface) provider(212) enabling the customized AD contents to be streamed on a scheduled AD insertion time by requesting streaming to the AD contents server.
