A method for format conversion includes providing (10) a first interlaced video signal including non-progressive video of a first resolution, downconverting (16) fields of the first resolution to fields of a second resolution, and combining and interlacing (18) the fields at a third resolution. The video signal is transmitted (20) at the third resolution. The video signal of the third resolution is deinterlaced (32) to form a progressive format video. The progressive format video is converted (34) to the first non-progressive resolution by alternately adjusting position of the progressive format of the third resolution up and down to make upper and lower fields, respectively, of the first resolution for display. |
