Abstract
Abstract Display is made according to the user's request by using the time information recorded on the disk. A disk contains a management area in which management data is recorded and a data area in which programs are recorded. Recorded in the management area are the absolute time information on the starts of the programs and the in-program relative time information on the starts of data units constituting each program. In the absolute time display mode, the absolute time information for display is obtained from the absolute time information on the program being reproduced and the relative time information on the data unit of the program being reproduced. In the relative time display mode, the absolute time information of the program being reproduced is set at 0, and the absolute time information for display is obtained from the relative time information on the data unit of the program being reproduced. In the frame number display mode, the frame information on the output image is counted and the current frame number is determined.
