Claim 0:
1. A method for decoding a video signal, with a decoding apparatus, comprising:
determining, with the decoding apparatus, a current block by dividing a coding block,
wherein the division of the coding block is performed recursively based on both a quad-division and a binary-division,
wherein the quad-division is performed without extracting division information for the quad-division from a bitstream,
wherein the binary-division is performed by using a plurality of flags extracted from the bitstream,
wherein the plurality of flags includes a first flag for indicating whether to use a binary-division type and a second flag for specifying a division direction of the binary-division, and
wherein the second flag equal to a first value indicates a vertical direction while the second flag equal to a second value indicates a horizontal direction;
obtaining, with the decoding apparatus, a residual signal of the current block by decoding the bitstream;
generating, with the decoding apparatus, a prediction signal of the current block by performing an intra prediction based on reconstructed pixel values of a neighboring block;
reconstructing, with the decoding apparatus, the current block using the residual signal and the prediction signal; and
applying an in-loop filter to a reconstructed image including the current block.
