1. An apparatus for calculating available channels considering a priority in a TVWS, comprising:
a communication module configured to receive a request for information on usable available channels from a TV Band Device (TVBD); an available channel calculation unit configured to calculate one or more available channels for multiple regions outside a radius of a DTV service usable by the TVBD based on one or more predetermined reference parameters according to the request; a priority assignment unit configured to assign a priority to each of the calculated available channels, generate an available channel list including the available channels to which the priorities are assigned, and provide the TVBD with the generated available channel list; and a database configured to store the available channels, to which the priorities are assigned, calculated for each TVBD, wherein a region outside the radius of the DTV service for protecting the DTV service is divided into a plurality of regions with a predetermined interval, so that the priority is differently determined for the multiple regions that are within the plurality of regions that are divided.
