Video encoding apparatus, video decoding apparatus, video encoding method, video decoding method, and computer program

A video encoding method for allowing filtering processing to be performed for a predicted value in an inter-frame prediction, the video encoding method comprising:

• a first step for holding multiple kinds of filter coefficients determined beforehand;
• a second step for holding identification information uniquely defined for each of the multiple kinds of filter coefficients;
• a third step for selecting, in each unit of coding control data, one from among the multiple kinds of filter coefficients held in the first step;
• a fourth step for selecting, in each unit of coding control data, the identification information uniquely defined for the filter coefficient selected in the third step, from among the multiple kinds of identification information held in the second step;
• and
• a fifth step for generating encoded data including the identification information selected in the fourth step.

A computer readable storage medium, comprising:

• a program encoded and stored in a computer readable format to cause a computer to execute a video encoding method for allowing filtering processing to be performed for a predicted value in an inter-frame prediction, the video encoding method comprising steps of:
• a first step for holding multiple kinds of filter coefficients determined beforehand;
• a second step for holding identification information uniquely defined for each of the multiple kinds of filter coefficients;
• a third step for selecting, in each unit of coding control data, one from among the multiple kinds of filter coefficients held in the first step;
• a fourth step for selecting, in each unit of coding control data, the identification information uniquely defined for the filter coefficient selected in the third step, from among the multiple kinds of identification information held in the second step;
• and
• a fifth step for generating encoded data including the identification information selected in the fourth step.
