Abstract: An image data of pictures constituting moving image data is encoded to generate an encoded video stream. In this case, the image data of the pictures constituting the moving image data is classified into a plurality of levels and encoded to generate a video stream having the image data of the pictures at the respective levels. Hierarchical composition is equalized between a low-level side and a high-level side, and corresponding pictures on the low-level side and the high-level side are combined into one set and are sequentially encoded. This allows a reception side to decode the encoded image data of the pictures on the low-level side and the high-level side with a smaller buffer size and a reduced decoding delay.

Decoding timing information, which has been set so that a higher layer has a shorter decoding time interval of the encoded image data of each of the pictures, is added to the encoded image data of the pictures of each of the layers. The operations enable a reception side to perform a favorable decoding process commensurate with its decoding capability.

Abstract: Moving image data of a wide viewing angle image is divided into blocks to obtain a coding target block. A motion-compensated reference block is extracted for each coding target block. The reference block is subjected to adjustment processing of rotation and/or scaling. A residual signal is calculated on the basis of a pixel value of the coding target block and a pixel value of the reference block subjected to the adjustment processing for each coding target block, and the residual signal of the coding target block is coded to obtain an encoded stream. Adjustment processing information is inserted into the encoded stream together with the motion vector for each coding target block. The residual can be reduced, the coding bit rate can be reduced, and consequently the coding performance of motion prediction can be improved.
