Interlaced video: This technique uses two fields to create a frame. One field contains all the odd lines in the image, the other contains all the even lines of the image. Only CRT displays

and plasma displays are capable of displaying interlaced signals.
Progressive video: is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence.

Progressive scan is used for most computer monitors, all LCD computer monitors, and most HDTVs.
PAL: Phase Alternating Line is an analogue television colour encoding system. It refer to the 625-line/50 Hz (576i) television system in general.
NTSC: National Television System Committee, is the analog television. offers very slightly smoother motion than PAL. NTSC receivers have a tint control to perform colour correction

manually. If this is not adjusted correctly, the colours may be faulty. The PAL standard automatically cancels hue errors by phase reversal, so a tint control is unnecessary.
