Patent ID: 7068915

Claim:
An apparatus for controlling a display time point of an MPEG bit stream of a recording medium, comprising: a crystal oscillator configured to generate a system clock frequency; a counter initialized according to a system clock reference (SCR) and configured to receive the system clock frequency from the crystal oscillator, count it, and output a system time clock (STC), in a normal decoding mode; a PTS (Presentation Time Stamp) controller configured to receive and store a presentation time stamp of a predetermined picture in a special decoding mode, and output the stored presentation time stamp as an initial value of the counter when the apparatus returns to a normal mode; and a comparator configured to receive the system time clock from the counter and a presentation time stamp of a predetermined picture, compare them, and output a display command signal in the case that the system time clock and the presentation time stamp of a predetermined picture are identical to each other upon comparison.
