Interlaced Scan

Definition: The way a television decodes an image – a frame is broken into two fields, odd (1, 3, 5, 7…) and even (2, 4, 6, 8…). A television will scan 60 fields per second with 30 odd and 30 even fields created. By combining the two fields every 1/30 of a second, a frame is created thus creating 30 frames per second – a standard in television broadcasting.
