1. A method for displaying interlaced video data on a non-interlaced monitor, the interlaced video data comprising a plurality of paired fields, each pair of fields being vertically offset relative to each other by one-half of a field line spacing distance, each field comprising a plurality of lines of video data, the method including:

  • (a) capturing a first field and a second field of each pair of fields into respective buffers;

    (b) scaling each of the first field and second field of each pair of fields to fill vertical resolution of the non-interlaced monitor;

    (c) adjusting one of the first field or second field of the pair of fields to substantially correct for the vertical offset between the pairs of fields, where said adjusting is performed concurrently with said scaling;

    (d) displaying the first field of each pair of fields on the non-interlaced monitor in a first time period; and

    (e) displaying the second field of each pair of fields on the non-interlaced monitor in a second time period subsequent to the first time period.
