A recording medium storing an AVCIip structured by multiplexing video stream and a graphics stream. The graphics stream represents a moving picture made of a plurality of pictures, and the graphics stream includes graphics data representing graphics to be combined with the pictures. The graphics stream also includes window information (WDS) that specifies a window for rendering the graphics, and that indicates a width, a height and a position of the window on a plane which is a plane memory of a reproduction apparatus that combines the graphics with the pictures. The graphic stream includes also a data packet containing a Decode Time Stamp (DTS), and the processor of a playback apparatus starts a process for decoding the graphics data on time indicated by the decode time stamp.
