Abstract:
1. A method for filling into a frame buffer for an interlaced display a frame having a first field and a second field, the method comprising the steps of: (a) calculating a first multi-sample of the first line of the first field, wherein bottom sub-pixels of said first multi-sample are the top sub-pixels of a multi-sample of the identical-numbered line of the second field; (b) writing said first multi-sample into the frame buffer; (c) calculating a next multi-sample of the next line of the first field, wherein top sub-pixels of said next multi-sample are the bottom sub-pixels of a multi-sample of the previous line of the second field, and wherein bottom sub-pixels of said next multi-sample are the top sub-pixels of a multi-sample of the identical-numbered line of the second field; and (d) writing said next multi-sample into the frame buffer; (e) performing steps (c) and (d) for each line of the first field; (f) calculating a last multi-sample of the last line of the second field, wherein said last multi-sample consists of sub-pixels of a full multi-sample of the last line of the second field; and (g) writing said last multi-sample into the frame buffer.
