Patent ID: 6839500

Claim:
An apparatus for implementing a still function of a DVD comprising: a system decoder for receiving a data outputted from a DVD reproducing unit, decoding it and outputting A/V bit streams; a still detecting unit for detecting an inherent number of the A/V bit streams outputted from the system decoder, comparing it with an inherent number of a still frame outputted from a host computer, and outputting a still detect signal; a still processing unit for receiving the still detect signal from the still detecting unit and outputting a still flag to control a still time point; a bit stream buffer for receiving the A/V bit streams from the system decoder and buffering it; and an A/V decoder for being switched to a still mode by the still flag outputted from the still processing unit, decoding the A/V bit streams read from the bit stream buffer and displaying a still frame wherein the still processing unit comprises a comparator for comparing a write pointer signal of the bit stream buffer that is generated at the identical time point with a read pointer signal is changed.
