The present invention relates to a data transmission apparatus and method using a polarized antenna in a wireless AV system, and a data reception apparatus and method. The present specification provides a method for performing polarization alignment for a downlink on the basis of reciprocity, a method for performing polarization alignment for an uplink, and a method for performing polarization alignment independently for each DMG antenna when one data transmission apparatus or one data reception apparatus uses multiple DMG antennas. Optimal MIMO performance can be guaranteed by aligning polarization between multiple antennas of the data transmission apparatus and the data reception apparatus in the wireless AV system, the polarization alignment for a downlink or an uplink may be selectively performed on the basis of reciprocity, and polarization distortion can be reduced through the independent polarization alignment between each DMG antenna.
