Is 3D content delivered frame packed (jumbo 1920x2205) frames, Half Top And Bottom or Half Side By Side? I can't find an info panel on my TV with that info. Is it network-subjective? If so, what are the speeds needed for FHD3D?

Also, is VUDU working on 3D for the Xbox One app? If so, is there any info on what format that will be in?
