초록
A method and a device for performing encoding and decoding by using prediction are disclosed. In the encoding of a current block, a residual signal of a current block is generated on the basis of thecurrent block, a first prediction, and a second prediction. In addition, information on the residual signal encoded by encoding the residual signal is generated. The second prediction is a predictionfor a part of the current block. In the decoding of the current block, a reconstructed residual signal for the current block is generated. A reconstructed block for the current block is generated on the basis of the reconstructed residual signal, the second prediction, and the first prediction. The second prediction is a prediction for a part of the current block.
