1. A video decoding method performed by a device and comprising:
when at least one of a width and a height of a current coding unit is equal to or greater than a predetermined value, obtaining, from a bitstream, information indicating whether a combined prediction is applied for the current coding unit,
wherein, when the width and the height of the current coding unit are less than the predetermined value, the combined prediction is determined not to be applied for the current coding unit;
when the information indicates that the combined prediction is applied for the current coding unit, obtaining an inter prediction block by performing inter prediction on the current coding unit using a merge candidate list;
when the information indicates that the combined prediction is applied for the current coding unit, obtaining an intra prediction block by performing intra prediction on the current coding unit in a planar mode; and
obtaining a combined prediction block of the current coding unit by combining the intra prediction block and the inter prediction block according to a weight value.
