<p>A system and method for decoding a video bitstream (30) and displaying (26) the video with 3:2 pull-down using a frame buffer (24) whose size is not sufficient to hold an entire decoded frame. This is accomplished by using the additional time required by the display with 3:2 pull-down to decode (12) a portion of the frame for a second time. The present invention provides memory savings, additional flexibility in decoder design, and reductions in memory controller (22) complexity and power consumption. In the case of MPEG-2 decoders, the present invention allows the implementation of PAL/SECAM main profile at main level decoders with 3:2 pull-down using only a 16 megabit memory.</p> |
