Abstract
A video encoding apparatus, includes: a block partitioning unit to determine a partition form, among candidate partition forms, for partitioning a current block into one or more partition blocks; a prediction unit to generate one or more predicted blocks respectively corresponding to the one or more partition blocks by using a scale factor which indicates a ratio of pixel sampling; a subtractor to generate a residual block of the current block by subtracting the predicted blocks from one or more partition blocks corresponding thereto; a transformer to generate at least one transform block by transforming the residual block; a quantizer to generate at least one quantized transform block by quantizing the at least one transform block; and an encoder to encode, into the bitstream, information on the scale factor, information on the determined partition form and the at least one quantized transform block.
