Abstract: An apparatus and a method for providing a Digital Multimedia Broadcasting (DMB) service using a digital TeleVision (TV) and an external device are provided. It is determined whether a received broadcast channel supports a Multi Mode Service (MMS), and if so, one of subchannels included in the broadcast channel is set to a main channel. The digital TV reproduces a broadcast signal via the main channel, and broadcast signals of subchannels excluding the main channel are transmitted to at least one external device in communication with the digital TV.
