Definitions for "Interlaced Scanning"
The concept of splitting a TV picture into two fields of odd and even lines.
The process of combing two picture fields to produce a full frame. Field one scans the odd lines, and field two scans the even. The physical position of the fields interleave with each other to create the full frame.
Scan method used by the traditional television technology and the 1080i HDTV format. As opposed to progressive scanning in which the CRT's electron beam scans or "paints" all lines at once, interlaced scanning TVs paint odd-numbered lines in succession, then go back and fill in the remaining even-numbered lines.
