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 coding block is divided recursively based on at least one of a quad-division or a binary-division,
wherein the quad-division is performed without extracting first division information for the quad-division from a bitstream, and
wherein the binary-division is performed by using second division information for the binary-division extracted from the bitstream, the second division information indicating that the binary-division is used or specifying a division direction of the binary-division;
obtaining, with the decoding apparatus, quantized coefficients from the bitstream;
obtaining, with the decoding apparatus, a residual signal by performing inverse-quantization and inverse-transform on the quantized coefficients;
generating, with the decoding apparatus, a prediction signal of the current block by performing intra prediction based on reconstructed pixel values of a neighboring block adjacent to the current block; and
reconstructing, with the decoding apparatus, the current block using the residual signal and the prediction signal.
