Display apparatus and channel searching method thereof

摘要

A display apparatus and a method of searching for a channel in the display apparatus includes a plurality of tuners and a plurality of antenna ports respectively connected to the plurality of tuners. The method includes receiving a channel search command; if the channel search command is input, searching for one of the plurality of antenna ports that is connected to a satellite antenna to receive a broadcasting signal, if one of the plurality of antenna ports is connected to the satellite antenna to receive the broadcasting signal, setting one of the plurality of tuners connected to the one antenna port, to a main tuner, and performing a channel search through the tuner set to the main tuner. Therefore, although an antenna port connected to one of the plurality of tuners initially set to a sub tuner, the display apparatus performs a channel search through the corresponding tuner.
