CA 2570282

A method and apparatus for reducing block artifacts during a residual prediction in a multilayer-based video coding are disclosed. The multilayer-- based video encoding method includes obtaining a difference between a predicted block for a second block of a lower layer, which corresponds to a first block included in a current layer, and the second block; adding the obtained difference to a predicted block for the first block; smoothing a third block generated as a result of the addition using a smoothing function; and encoding a difference between the first block and the smoothed third block.
