Abstract:
1. An image encoding apparatus that encodes image data, the image encoding apparatus comprising: an image encoding unit configured to receive an input of the image data and image parameters and generate encoded image data by performing image encoding on the image data with reference to the image parameters and furthermore binarizing and entropy-encoding the image data; a parameter processing unit configured to (i) output, as parameter information, a parameter set that is a duplication of a part of the image parameters and that is referred to when the encoded image data is entropy-decoded, without encoding the parameter set, and (ii) encode the image parameters to generate and output encoded image parameters; and a stream generation unit configured to generate and output, to an external output apparatus, a stream including the encoded image data obtained from the image encoding unit and header information including the parameter information not encoded and the encoded image parameters that are outputted from the parameter processing unit, wherein the header information redundantly includes the non-encoded parameter set as the parameter information and as a duplicate of an encoded parameter set included in the encoded image parameters.
