Abstract
A picture coding apparatus reduces a load in decoding. The picture coding apparatus codes each picture according to a picture type of the picture. The picture types include at least an I picture, a P picture, a B picture, and a skipped picture. A first coder is configured to code first supplementary information, including coded pictures and indicating respective picture types of the coded pictures, in a decoding order of the coded pictures. A second coder is configured to code second supplementary information, indicating respective pieces of picture structure information of the coded pictures, in the decoding order. A writer is configured to write, at a position prior to a starting picture, the first supplementary information coded by said first coder and the second supplementary information coded by said second coder.
