| 1. A method for managing multiview videos, comprising the steps of:
maintaining a reference picture list for each current frame of a plurality of multiview videos, the reference picture list
indexing temporal reference pictures, spatial reference pictures and synthesized reference pictures of the plurality of multiview
videos; and
predicting each current frame of the plurality of multiview videos according to reference pictures indexed by the associated
reference picture list, in which each current frame includes a plurality of macroblocks, and the predicting is macroblock
adaptive according to a selected one of a plurality of prediction modes, and in which the predicting minimizes a cost function
adaptively on a per macroblock basis according to
 where J(m)=D(m)+λR(m), and D is distortion, λ is a weighting parameter, R is rate, m indicates a set of candidate prediction
modes, and m* indicates an optimal prediction mode that is selected based on a minimum cost.
