A reception device comprising a reception unit configured to receive a container containing a first stream having encoded image data of pictures on a low-level side corresponding to the one or more lowest levels of a plurality of levels of a hierarchical level structure, a second stream having encoded image data of pictures on a high-level side corresponding to the one or more highest levels of the plurality of levels of the hierarchical level structure, and a program map table, PMT, wherein said first and second stream are generated by subjecting image data of the picture constituting moving image data to hierarchical encoding, wherein the PMT includes a first descriptor describing a level specified value of the first stream in correspondence with the first stream and a second descriptor describing a level specified value of a bit stream formed from a combination of the first stream and the second stream, the first descriptor corresponding to the first stream and the second descriptor corresponding to the second stream; wherein the encoded image data has a network abstraction layer, NAL, unit structure, and the level specified value of the first stream is inserted together with the level specified value of the bit stream formed from a combination of the first stream and the second stream into an NAL unit of SPS of the first stream; and wherein the image data of the picture are hierarchical encoded such that the picture order of composition of the encoded image data of pictures on the high-level side is either one picture behind or one picture ahead of the picture order of composition of the encoded image data of pictures on the low-level side; a processing unit (201, 203, 204, 205, 207) configured to: extract the first descriptor and the second descriptor from the container, detect up to which level decoding is enabled according to a decoding capability, decode the first stream or both the first stream and the second stream contained in the received container according to the decoding capability to obtain the image data of the pictures constituting moving image data, perform a frame rate interpolation or a frame rate sub-sampling to the decoded image data of the pictures based on a display capability of a display unit for displaying the moving image data; and supply the interpolated or sub-sampled image data to the display unit. a reception unit configured to receive a container containing a first stream having encoded image data of pictures on a low-level side corresponding to the one or more lowest levels of a plurality of levels of a hierarchical level structure, a second stream having encoded image data of pictures on a high-level side corresponding to the one or more highest levels of the plurality of levels of the hierarchical level structure, and a program map table, PMT, wherein said first and second stream are generated by subjecting image data of the picture constituting moving image data to hierarchical encoding, wherein the PMT includes a first descriptor describing a level specified value of the first stream in correspondence with the first stream and a second descriptor describing a level specified value of a bit stream formed from a combination of the first stream and the second stream, the first descriptor corresponding to the first stream and the second descriptor corresponding to the second stream;
