Classification: CPC H | IPC H

Claim 5:
6. A device for transmitting a compressed video data, the device comprises:
a processor to generate the compressed video data which including information on motion information of a current block and information on residual coefficients of a transform block included in the current block; and
a transmitting unit to transmit the compressed video data,
wherein prediction samples of the current block are obtained based on the motion information of the current block,
wherein an inverse-quantization is performed on the residual coefficients of the transform block,
wherein when it is determined that an inverse-transform is not skipped for the transform block, a transform type for the transform block is determined,
wherein residual samples of the transform block are obtained by performing the inverse-transform on inverse-quantized residual coefficients of the transform block based on the determined transform type,
wherein the current block is reconstructed based on the prediction samples and residual samples of the current block,
wherein whether a transform skip flag, indicating whether the inverse-transform is skipped or not for obtaining the residual samples, is included in the compressed video data or not is determined based on whether the current block including the transform block is partitioned into two transform blocks or not.
