HDTV blur

HDTV blur is a common term used to describe a number of different artifacts on consumer modern high definition television sets:

The following factors are generally the primary or secondary causes of HDTV blur; in some cases more than one of these factors may be in play at the studio or receiver end of the transmission chain.

• Pixel response time on LCD displays (blur in the color response of the active pixel)
• Slower camera Shutter speeds common in hollywood production films (blur in the HDV content of the film)
• Blur from eye tracking fast moving objects on sample-and-hold LCD, Plasma, or Microdisplay.
• Resolution resampling (blur due to resizing image to fit the native resolution of the HDTV)
• Blur due to 3:2 pulldown and/or motion-speed irregularities in framerate conversions from film to video
• Computer generated motion blur introduced by video games
