Claim 0:
1. An image decoding method comprising:
when a prediction mode of a first coding unit is a combined inter-intra prediction mode, determining a first prediction block of the first coding unit by using a weighted sum of a first sample value according to intra-prediction and a second sample value according to inter-prediction;
when the prediction mode of the first coding unit is the combined inter-intra prediction mode, determining a value of a boundary filtering strength applied to a boundary between a first reconstruction block and a second reconstruction block, wherein the value of the boundary filtering strength is equal to a value of a boundary filtering strength used when the prediction mode of the first coding unit is an intra prediction mode; and
performing deblocking filtering on samples adjacent to the boundary based on the determined value of the boundary filtering strength,
wherein the first coding unit and a second coding unit are obtained by splitting an upper coding unit.
