RECORDING MEDIUM, REPRODUCTION DEVICE, RECORDING METHOD, PROGRAM, AND REPRODUCTION METHOD

摘要

A digital stream obtained by multiplexing a video stream and a graphics stream is recorded on a BD-ROM. The video stream constitutes moving picture data consisting of a plurality of picture data while the graphics stream includes a PES packet (ICS) containing state control information and a PES packet (ODS) containing graphics data. The graphics data is data constituting an interactive screen. The state control information is information used for changing the button state in the interactive screen according to the moving picture data reproduction stage and user operation. The ICS is added by a PTS indicating the display timing of the picture data to be synchronized with the interactive screen. The ODS is added by a PTS indicating the decode timing of the graphics data which is earlier than the display timing.
