Abstract (en)

[origin: WO2006132509A1] A method and apparatus for decreasing block artifacts in multilayer-based video coding are provided. A multilayer-based video encoding method includes calculating a difference between an inter prediction block for the block of a lower layer picture, which corresponds to an arbitrary block of a current picture, and the block of the lower layer picture, adding the calculated difference to an inter prediction block for the block of the current picture, smoothing a block, which is generated by the adding, using a smoothing filter, and encoding a difference between the block of the current picture and a block generated by the smoothing.
