Patent ID: 8803945

Claim:
A three dimensional (3D) video data processing method for use in a broadcast receiver, the method comprising: receiving a broadcast signal including three dimensional (3D) video data, a display condition descriptor, a viewing distance table including a plurality of viewing distance information, and a screen size table including a plurality of screen size information; storing the viewing distance table and the screen size table; extracting the display condition descriptor of the 3D video data from the broadcast signal, wherein the display condition descriptor includes: viewing distance mapping table information linking the display condition descriptor to the viewing distance table, first parameter information indicating a first index number applied to the viewing distance table, screen size mapping table information linking the display condition descriptor to the screen size table; and second parameter information indicating a second index number applied to the screen size table, wherein the viewing distance table includes first index number information having same value of the first index number, and viewing distance information specifying a value of an intended viewing distance corresponding to the first index number information, and wherein the screen size table includes second index number information having same value of the second index number, and screen size information specifying a value of an intended screen size corresponding to the second index number information, and controlling an output of the 3D video data using the viewing distance information and screen size information.
