All current proposals for filling in Table A seem to involve agreement by some number of major movie studios—that is, members of the Motion Picture Association of America (MPAA) -- and, perhaps, agreement by some number of major electronics companies or other corporations. No agreement has been reached within BPDG, but various "vehicles" or "methods" for approving technologies have been suggested. These typically employ a formula such as "n% of Major Studios and m% of manufacturers". No studio proposal, has yet contemplated the possibility that technologies could be approved without any Hollywood sign-off. Thus, the discussion appears to be centered on choosing values for the percentages to be plugged into these formulas.
