Claim:
1. A method of decoding a video signal by a decoding apparatus, the method comprising: receiving, by the decoding apparatus, the video signal including a current block to be partitioned into a plurality of partitions; parsing, by the decoding apparatus from the video signal, first coded block indication information of the current block, the first coded block indication information specifying whether the current block contains transform coefficient information; when the first coded block indication information corresponds to a value of 1, parsing, by the decoding apparatus from the video signal, second coded block indication information of a first partition of the plurality of partitions, the second coded block indication information specifying whether the first partition contains transform coefficient information; when the second coded block indication information corresponds to the value of 1, parsing, by the decoding apparatus from the video signal, transform coefficient information of the first partition; obtaining, by the decoding apparatus, residual data of the first partition by performing an inverse-transform operation based on the parsed transform coefficient information of the first partition; and reconstructing, by the decoding apparatus, the first partition using the obtained residual data of the first partition.
