Abstract
A broadcast/multicast (BCAST) service, specifically, a BCAST service system for transmitting broadcast contents to terminals when a network load is small and a contents transmission method using the same are disclosed. When contents are broadcast by using a distribution window (DM) and a presentation window (PW), the terminals feed back a message indicating reception confirmation of the contents to the network, such that the contents reception success rate between the terminals and the network can be improved.
