The method may include initiating a view of real-time broadcasting content at a broadcasting reception terminal; determining a view suspension time point in response to a user input during the real-time broadcasting; transmitting, to a history management server, view history data comprising the view suspension time point and content identification information, the transmitted view history data interacting with a non-real-time video service server; requesting the non-real-time video service server for non-real-time broadcasting content corresponding to the real-time broadcasting content; and receiving the non-real-time broadcasting content that is provided from the non-real-time video service server and corresponds to a broadcasting time after the view suspension time point. A bi-directional multimedia service free from restrictions on a place and a time may be achieved by providing a substantially real-time video service through a linkage between a real-time broadcasting and a non-real-time video service.
