What does 1080 24p mean on a HDTV?

24p (1080p)

1080p is a high-definition video format with resolution of 1920 x 1080 pixels. The "p" stands forprogressive scan, which means that each video frame is transmitted as a whole in a single sweep. The main advantage of 1080p TVs is that they can display all high-definition video formats withoutdownconverting, which sacrifices some picture detail.


1080p TVs display video at 60 frames per second, so this format is often referred to as 1080p60. The video on most Blu-ray discs is encoded at film's native rate of 24 frames per second, or 1080p24. For compatibility with most current 1080p TVs, high-definition players internally convert the 1080p24 video to 1080p60. By late 2007, many HDTVsincluded the ability to accept a 1080p24 signal directly. These TVs don't actually display video at 24 frames per second because that would cause visible flicker and motion stutter. The TV converts the video to 60 frames per second or whatever its native display rate is. The ideal situation would be to display 1080p24 at a multiple of 24 frames per second, like 72, 96, or 120 frames per second, to avoid the motion judder caused by 3-2 pulldown, which is required when converting 24-frames-per-second material to 60 frames per second.
