VIDEO ENCODING METHOD AND VIDEO DECODING METHOD

摘要

Provided are a video encoding method and a video decoding method capable of deriving a motion vector that is optimal for a picture to be encoded, and also capable of improving encoding efficiency. A video encoding device (100) comprising: a reference picture list management unit (111) for assigning a reference picture index to a reference picture and creating a reference picture list together with a display order or the like; a skip mode prediction direction determination unit (112) for determining the prediction direction of a skip mode of a block to be encoded, by using a reference picture list (1) and a reference picture list (2); and an inter-prediction controller (109) for performing a cost comparison of a motion vector detection mode, a direct mode, and the skip mode for generating a predicted image using the predicted motion vector generated according to the prediction direction established by the skip mode prediction direction determination unit (112), and determining a more efficient inter-prediction mode.
