Interlace Scan A way to scan vertical lines onto a TV picture by scanning all the odd lines first, then filling in the even lines. The fields are aligned and timed so that, with a still image, the human eye blends the two fields together and sees them as one. Interlace scanning allows only half of the lines to be transmitted and presented at any given moment. The alternative to Interlace Scan is Progressive Scan
