To enable satisfactory decoding processing corresponding to a decoding capability on a reception side.Image data of pictures constituting moving image data are sorted into multiple hierarchies, image data of pictures of each of the sorted hierarchies are encoded, and video data including the encoded image data of the pictures of each of the hierarchies is generated. A container of a predetermined format including the video data is transmitted. The multiple hierarchies are divided into a predetermined number of hierarchy groups, the predetermined number being two or more, and identification information for identifying a hierarchy group to which encoded image data of each picture included in the video data belongs is inserted into a packet as a container of the video data.
