Abstract
A system and method for synchronizing a decoded, interlaced-field data stream with an interlaced field display. A system for displaying an MPEG encoded data stream includes an MPEG decoder which converts the encoded data stream into a sequence of frames. Each frame has an associated top field, bottom field, top-field-first flag, and repeat-first-field flag. The system also includes a display processor which receives the flags and determines a field display sequence for each frame which conforms to an overall display sequence which strictly alternates between top and bottom fields. This strict alternation in enforced even when the decoded field sequence does not adhere to a strict alternation. The system achieves this result with a worst-case temporal distortion of one field by inserting or omitting a 3:2 pulldown frame at each broken alternation point.
