Abstract
A method, apparatus and system for Digital Multimedia Broadcasting (DMB) service are provided. A DMB receiving terminal identifies a channel service area in which the DMB receiving terminal is currently located based on an identified current location, and configures a channel information list by searching only a frequency band corresponding to the channel service area. When the channel service area is changed, the DMB receiving terminal searches a pre-stored connection channel list, and identifies a predetermined channel established as a transition channel corresponding to a channel which the DMB receiving terminal has received, from channels belonging to the changed channel service area. The DMB receiving terminal then receives the identified channel and provides terrestrial DMB service, thereby reducing a channel search time period and smoothly providing the terrestrial DMB service.
