MULTIVIEW VIDEO ENCODING METHOD USING REFERENCE PICTURE SET FOR MULTIVIEW VIDEO PREDICTION AND DEVICE THEREFOR, AND MULTIVIEW VIDEO DECODING METHOD USING REFERENCE PICTURE SET FOR MULTIVIEW VIDEO PREDICTION AND DEVICE THEREFOR
The present invention provides methods of encoding and decoding multi-view video by performing inter-prediction and inter-view prediction on each of pictures of multi-view video according to views. A prediction encoding method of encoding a multi-view video includes determining a reference picture set including at least one short term reconstructed picture having a different reproduction order from that of a current picture and a reference picture set including at least one long term reconstructed picture, among same view reconstructed pictures that are reconstructed prior to the current picture, and determining a reference picture set including at least one short term reconstructed picture having the same reproduction order as that of the current picture, among different view reconstructed pictures that are reconstructed prior to the current picture; determining at least one reference list between a first reference list including at least one reconstructed picture having a reproduction order earlier than that of the current picture and at least one reconstructed picture having the same reproduction order as that of the current picture and having a smaller view identifier (VID) than that of the current picture, among the determined reference picture sets, and a second reference list including at least one reconstructed picture having the same reproduction order as that of the current picture and having a later reproduction order than that of the current picture and at least one reconstructed picture having the same reproduction order as that of the current picture and having a greater VID than that of the current picture; determining at least one reference picture and reference block for a current block of the current picture by using the determined at least one reference list; and performing at least one selected from inter-prediction and inter-view prediction for the current block by using the reference block.
