• inserting audio information into information signal portions of said video format signal corresponding to predetermined ones of said plurality of blocks and inserting video information into information signal portions of said video format signal corresponding to remaining blocks;
• recording said video format signal on a recording medium;
• reproducing said video format signal from said recording medium, said reproducing step including one of the steps of (1) masking said information signal portions of said video format signal corresponding to said predetermined blocks so that no video information is displayed in the corresponding predetermined blocks of said two-dimensional image, and (2) replacing the audio information inserted into information signal portions of said video format signal corresponding to said predetermined blocks with video information to be displayed in the corresponding predetermined blocks of said two-dimensional image.
