It seems rather easy to introduce 3D in ATSC and other DTV standards, if it's done with the 2D+delta formats. No need to replace any of the existing receivers, and 2D receivers would continue to show the same resolution as before. Not sure about the optical disc formats. Existing players may be able to work with new 2D+delta discs, but I'm not sure. Depends on the digital frame structure.
