 Progressive scan Progressive or noninterlaced scanning is any method for displaying, storing or transmitting moving images in which the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems. Image File history File links Progressive_scan_full_frame-Vollbildverfahren_volles_Bild. ...

Advantages of progressive scan:
- Simpler video processing equipment;
- Easier compression;
- Higher resolution and fewer artifacts in video with motion compared to interlaced video of the same line rate.
Usage in TVs, video projectors and monitors Progressive scan (also known as: P-Scan) is used for most cathode ray tube (CRT) computer monitors and HDTVs as the source signal is progressive by nature. (Other CRT-type displays, such as SDTVs, typically use interlaced displays.) Cathode ray tube employing electromagnetic focus and deflection Cutaway rendering of a color CRT: 1. ...

Some TVs, and most video projectors have one or more progressive scan inputs. Before HDTV became common, some high end devices support 480p (480 vertical lines or resolution with progressive scan.) This allowed these devices to be used with devices which output progressive scan like progressive scan DVD players. HDTVs commonly support the progressively scanned resolutions or 480p and 720p. 1080p displays are available, but usually more expensive than the comparable lower resolution HDTV models. See TV (disambiguation) for other uses and Television (band) for the rock band European networks National In much of Europe television broadcasting has historically been state dominated, rather than commercially organised, although commercial stations have grown in number recently. ...

Advantages of progressive scan - Higher resolution and fewer artifacts in video with motion compared to interlaced video of the same line rate
- Easier video compression
- Subjectively increased vertical resolution
- The perceived vertical resolution of an interlaced image is usually equivalent to multiplying the active lines by about 0.6. This means that, when viewing progressive sourced material, a progressive display will show a more detailed image, when compared to an interlaced one, even if both have exactly the same display resolution.
- No flickering of narrow horizontal patterns
- Simpler video processing equipment
- The ghosting effect is also reduced in game consoles
Display standards comparison The display resolution of a digital television or computer display typically refers to the number of distinct pixels in each dimension that can be displayed. ...

Disadvantages of progressive scan - Progressive scan will have half the frame rate of an interlaced scan's (NTSC/Pal) field rate, at a given line rate. This reduces motion smoothness, which may be a disadvantage in fast-changing images such as sports coverage. To maintain the same smoothness, double the line rate is required.
