The present invention allows usable information to be selected by comparing information regarding encoding with conditions regarding encoding processing. When delay modes, picture structures, and pulldown modes do not match each other between previous encoding time and re-encoding time, parameters are not reused. When they match and image frames do not match, a picture type is reused. When a bit rate in the previous encoding is smaller than that in the current encoding and a chroma format is larger than the current chroma format, a picture type and a motion vector are reused. When the conditions are not satisfied, parameters are supplied and received and a determination is made as to whether or not chroma formats match each other. When the chroma formats do not match each other, picture-type information, motion-vector information, and quantization-value information are reused. When the chroma formats match each other, stream data input to a decoding unit is output. The present invention can be applied to an encoding unit, an encoding device, or a transcoder.
