Abstract

The purpose of the present invention is to improve the rapid SPU playback scheme in a DVD player. In order to achieve this end, the method in accordance with the invention comprises the steps of: comparing the system time clock (STC) with the execution time of an instruction set that provides display control in the sub-picture units (SP_DCSQ_STM_N), forcing the display of pixel data (PXD) contained in a sub-picture unit to suspend operation and to proceed to instruction interpretation of the instruction set in a next sub-picture unit if said comparison means determines, when the sub-picture units are being rapidly played back, that the system time clock performing a rapid increment operation has a greater value than the execution time of the instruction set at least one ahead (SP_DCSQ_STM_N+1) and continuously repeating the instruction interpretation until the execution time of the instruction set coincides with the system time clock.
