Abstract
A method for encoding image signal, according to the present invention, can: encode a partial block coefficient flag indicating whether a coefficient of a current partial block is a non-zero coefficient; encode a first flag indicating whether an absolute value of the coefficient is greater than 1, encode a second flag indicating whether the absolute value of the coefficient is greater than 2; encode the residual coefficients, which have not been encoded, on the basis of the first flag or the second flag in the current partial block; and encode a code for the coefficient of the current partial block.
Claims8
A method for encoding a video signal with a decoding apparatus, the method comprising:
- determining, with the decoding apparatus, a shape of a current block;
- determining, with the decoding apparatus, a number or type of available intra prediction modes of the current block, based on the shape of the current block, the available intra predictions mode being a group of intra prediction modes available for intra prediction of the current block;
- and
- performing, with the decoding apparatus, the intra prediction on the current block, based on the available intra prediction modes.
