Abstract: Video coding according to the disclosure of the present application includes generating a predictive signal of a target object either by means of intra-prediction or inter-prediction. The generated predictive signal of the target object then undergoes filtering to smooth out a transition of pixel signals from a neighboring block to the target block. In the disclosure of the present application, the filtering is performed only when the filtering is necessary. A parameter indicating whether to execute or not to execute the filtering is sent from the encoder to the decoder. The present application also discloses provision of multiple types of transformation processes. A selection signal is used to select one type of transformation process from the multiple types of transformation processes. Alternatively, one type of transformation process is selected according to whether to execute or not to execute the filtering.
