1. A video decoding method performed by a device and comprising:
splitting an upper coding unit into a plurality of lower coding units including a current coding unit;
when at least one of a width and a height of the 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;
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.
