The Seattle PBS station is changing from 1080i to 720p. This is not a move to add more subchannels but to show the HD version of their five subchannels without breaking up—what a joke. The only reason you would change your local PBS station is for better picture quality.

In a recent message to Phoenix TV viewers, KAET General Manager Greg Gizzi stated that the station would change its format, add a new sub-channel, and restore the analog signal. Currently, the station carries one audio and one video sub-channel. Gizzi asked if other PBS stations are down-rezzing their pictures in his message.

KAET is changing from 1080i to 720p

KAET, a Seattle-area PBS station, is changing from 1080i to 720P to meet audience demands for high-definition programming. 1080i has 1,920×1,080 pixels and is transmitted at 30 frames per second. Compared to 720p, which has 60 frames per second, 1080i is smoother and more detailed.

The difference between 1080i and 720p is primarily related to the resolution. While both video formats have the exact answer, 1080i produces a higher-quality image. 1080i, also known as full HD, uses an interlaced scan picture, sending half the detail every 60th seconds and the other half every 30th. It produces better detail than 720p but will result in jagged edges and a blurred effect when fast-moving objects are shown.
