ABSTRACT:
Disclosed is a method for efficiently scanning a frequency of a new broadcasting area when a DVB-H receiving terminal moves. To this end, the DVB-H terminal stores in advance in a table DVB-H frequency changes according to the broadcasting area based on each cell whenever it moves. Then, the DVB-H receiving terminal preliminarily scans the DVB-H frequency previously stored in response to the current cell when the DVB-H receiving terminal moves in the future. If there exist one or more DVB-H frequencies stored in response to each cell, the DVB-H receiving terminal scans the stored DVB-H frequencies one by one in order to find a DVB-H frequency having an intensity higher than a predetermined intensity. The DVB-H receiving terminal quickly and efficiently scans the DVB-H frequencies according to the priority without scanning within all the DVB-H frequency ranges so that it can effectively minimize power consumption.
