Decoding device and decoding method, and encoding device and encoding method

An encoding device, comprising:

• a motion compensation unit generating a prediction image by performing motion compensation of a reference image at a time different from the time of an encoding target current image based on a motion vector detected within a tile when a picture of the current image is split into the tiles and encoded;
• an encoding unit encoding the current image and generating encoded data using the prediction image generated by the motion compensation unit;
• a setting unit setting tile splittable information indicating that decoding is allowed for each unit of the tiles;
• and
• a transmission unit transmitting the encoded data generated by the encoding unit, and the tile splittable information set by the setting unit.

An encoding method, comprising:

• a motion compensation step performed by an encoding device which generates a prediction image by performing motion compensation of a reference image at a time different from the time of an encoding target current image based on a motion vector detected within a tile when a picture of the current image is split into the tiles and encoded;
• an encoding step performed by the encoding device which encodes the current image and generating encoded data using the prediction image generated by the processing of the motion compensation step;
• a setting step performed by the encoding device which sets tile splittable information indicating that decoding is allowed for each unit of the tiles;
• and
• a transmission step performed by the encoding device which transmits the encoded data generated by the processing of the encoding step, and the tile splittable information set by the processing of the setting step.
