Abstract
A digital broadcast system and method including a user input unit, a digital broadcast signal receiver for receiving a digital broadcast signal including location information, a location information detector for detecting the location information from the receiver, and an output unit for outputting the received signal. The location information is used to provide various location-related services to the user. If the user requests route guidance to a specific place appearing in the broadcast scene, the user can receive route guidance to the specific place. When a place, details of which the user desires to know, appears in a scene of a digital broadcast that the user is watching through the digital broadcast receiver, the user can confirm the details of the place using the location information included in the received signal.
