Interlaced MVD format for free viewpoint video

new 3D video format which consists of one full resolution mono video and half resolution left/right videos is proposed. The proposed 3D video format can generate high quality virtual views from small amount of input data while preserving the compatibility for legacy mono and frame compatible stereo video systems. The center view video is the same with normal mono video data, but left/right views are frame compatible stereo video data. This format was tested in terms of compression efficiency, rendering capability, and backward compatibility. Especially we compared view synthesis quality when virtual views are made from full resolution two views or one original view and the other half resolution view. For frame compatible stereo format, experiments were performed on interlaced method. The proposed format gives BD bit-rate gains of 15%.
