Computer-readable storage medium

A computer-readable storage medium storing thereon a procedure for controlling a computer to play back a storage medium storing still picture group management information (VOBGI) for managing still picture data (VOB) and N still picture data (VOB) as a still picture group (VOBG), where N is an integer number equal to or larger than one, wherein said still picture group management information (VOBGI) includes a first recording time (F_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded first and a last recording time (L_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded last, said procedure comprising the steps of:

• receiving an entry of a predetermined time (TM);
• comparing said predetermined time with said first and last recording times (F_RECTM, LRECTM);
• and
• selectively playing back the still picture data (VOB) belonging to said still picture group (VOBG) satisfying a condition (F_RECTM<TM<L_RECTM) in which said predetermined time (TM) is equal to or later than said first recording time (F_RECTM) and equal to or earlier than said last recording time (L_RECTM).
