A video signal generating device for generating a video signal by decoding a bit stream comprises a writing means for writing into a prescribed bit position on one-bit plane having the same size as a block to be decoded a flag value indicating whether the block to be decoded is coded by intra-coding or coded by inter-coding, writing into a prescribed common area on the one-bit plane information indicating the coding division pattern of the block to be decoded, and writing into a prescribed switching interpretation area on the on-bit plane coding information in a data format corresponding to the intra-coding in the coding by intra-coding and coding information in a data format corresponding to the inter-coding in the coding by inter-coding, and a generating means for generating the video signal by overlapping the one-bit plane and a decoded image of the block to be decoded.
