I'm pretty sure only framepacking is an hdmi standard.
(h)sbs and (h)tab is nothing special hdmi-wise. Whether they're handled purely depends on the TV software (and optionally the box to tell the TV what kind of 3d is sent).
In the PDF linked in my post above, there is an approved way of flagging HSBS/FSBS and HTAB within the 3D spec (which I suppose makes the HSBS/HTAB 2D signals "3D"). There is optional support for FSBS (alongside line sequential, field sequential and other 3D stuff) as well (assuming the spec is correct) Appendix H has the oddball stuff.
According to the spec you flag 3D present in the HDMI Format bit of the VSIF, and then in the 3D_Structure field you can flag :
0000 Frame Packing
0110 Top and Bottom (which is HTAB)
1000 Side-by-Side Half (which is HSBS)
In Appendix H
0011 Side-by-Side Full is defined.
If this is done 3D compatible TVs will automatically switch into the correct modes I believe - even though HTAB and HSBS are standard 2D video resolutions (1920x1080 or 1280x720)
