Abstract
The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method, which are capable of sharing or predicting information related to a reference image of an image having a hierarchical structure. An enhancement encoding unit sets reference image specifying generation information used for generation of reference image specifying information of an enhancement image using reference image specifying information serving as information related to a reference image used when the enhancement image is encoded and reference image specifying information serving as information related to a reference image of a base image. The enhancement encoding unit encodes the enhancement image using the reference image, and generates encoded data. A transmission unit transmits the encoded data and the reference image specifying generation information. For example, the present technology can be applied to the encoding device.
