VIDEO PREDICTION METHOD CAPABLE OF PERFORMING BILATERAL PREDICTION AND UNILATERAL PREDICTION AND A DEVICE THEREOF, VIDEO ENCODING METHOD AND DEVICE THEREOF, AND VIDEO DECODING METHOD AND DEVICE THEREOF

摘要

Provided are inter prediction of a video, and encoding and decoding a video using an inter prediction. A video prediction method includes: determining reference information indicating at least one reference image for inter predicting an image; determining a first reference list and a second reference list, which each include the reference information and a reference order of the at least one reference image; and if the determined reference information indicates only images for uni-directional prediction, generating a reconstructed image by referring to images indicated by the first and second lists in a same reference order.
