Patent abstract

A method of effectively operating a Content-On-Demand (COD) system is disclosed. Requests for content are received from COD clients. If the requested content exists in a COD server and the content is content for one-to-one transmission, a session is set up between the COD server and one of the COD clients by providing access information for one-to-one transmission. Thereafter, the requested content is transmitted to the corresponding COD client in a one-to-one transmission manner, and then the session is terminated when the transmission is completed. If the requested content is content for one-to-N transmission, sessions are set up between the COD server and the respective COD clients by providing access information for one-to-N transmission. Thereafter, the requested content is transmitted to the corresponding COD clients in a one-to-N transmission manner when a one-to-N transmission requirement is met, and then the sessions are terminated when the transmission is completed.
