Abstract
A video signal generation apparatus for decoding a bit stream to generate a video signal, includes: a writing unit configured to write a flag value indicating whether a decoding target block has been coded by intra-coding or inter-coding in a specified bit position on one bit plane having a size the same as that of the decoding target block, to write information indicating a coding division form of the decoding target block in a specified common area on the one bit plane, and to write the coding information in a specified switch interpretation area on the one bit plane according to a data format conforming to the intra-coding if the decoding target block has been coded by intra-coding, and to write the coding information in the specified switch interpretation area according to a data format conforming to the inter-coding if the decoding target block has been coded by inter-coding; and a generation unit configured to generate a video signal by superimposing the one bit plane on a decoded image of the decoding target block.
