Claim:
1. A video encoding apparatus, comprising: a block partitioning unit configured to determine a partition form, among candidate partition forms, for partitioning a current block into one or more partition blocks, wherein the candidate partition forms include one or more asymmetric partition forms in which the current block is partitioned into a plurality of asymmetric partition blocks; a prediction unit configured to generate one or more predicted blocks respectively corresponding to the one or more partition blocks; a subtractor configured to generate a residual block of the current block by subtracting the predicted blocks from one or more partition blocks corresponding thereto; a transformer configured to generate at least one transform block by transforming the residual block; a quantizer configured to generate at least one quantized transform block by quantizing the at least one transform block; and an encoder configured to encode the at least one quantized transform block and information on the determined partition form into a bitstream, wherein the prediction unit is configured to wherein the encoder is configured to encode information on the scale factor into the bitstream to enable a video decoding apparatus to derive the predicted pixels from the reference picture in a scale corresponding to the information on the scale factor.
