A mobile terminal provides a broadcast receive service. More particularly, an apparatus and a method executes an application installed in advance via a channel change of a broadcast service. The apparatus includes a communication unit, a channel register unit, a channel determining unit, a memory unit, and a controller. The communication unit communicates with a remote controller to receive a control signal of the remote controller. A channel register unit registers an application installed in advance in a broadcast channel allocated to the mobile terminal to update channel information. A channel determining unit determines a channel changed by a user's remote controller manipulation. A memory unit stores channel information updated by the channel register unit. A controller processes to execute an application depending on a channel change of the remote controller. The channel determining unit determines the channel information to determine an application registered in the changed channel.
