EOPA Interlaced Scanning - correct answer The scanning of all the odd-numbered lines (First field) and the subsequent scanning of all the even-numbered lines. The two fields make up a complete television frame. Progressive Scanning - correct answer Each frame of a video is scanned by the electron beam as a single field. If slowed down, each frame would appear on the monitor in its entirety on the screen, rather than line by line. Y/C - correct answer A term used to describe the separation...
