Which HDTV format does Clear Creek Telephone & TeleVision use?
HDTV is available in two common formats: 720p and 1080i. The 720p format uses progressive scanning technology much like a computer monitor. It uses 720 scan lines to produce an image and the picture is refreshed 60 times per second. Progressive scanning produces smoother motion with less blurring. The 1080i format uses interlaced scanning technology. This uses 1,080 scan lines to produce an image and the picture is refreshed 30 times per second. Interlaced scanning produces sharper pictures in general and in particular when the image is still or has little motion. Clear Creek Telephone & TeleVision’s HDTV service supports both formats.
