In Reply to: Help with some video basics... posted by twisted on June 25, 2001 at 12:42:27:
Twisted,Unlike Rich's reply, we have useful information on our web site regarding the technology -- I have included a link below for you. In the meantime, I'll answer some of the questions on a basic level for you.
1) Progressive scan:
In traditional TV (aka interlaced scan referred to as 480i)) each frame (complete picture) is comprised of two fields with even lines in one field and odd lines in the other field. Together the fields make up the frame. The fields are displayed every 1/60th of a second, and a frame takes up 1/30th of a second. Progressive scan (480p) takes the entire frame and displays only completed frames. It does so at the same rate (1/60th of a second). As such, the image is much more detailed and solid to our eyes. There are other complications to this explained in our Progressive Scan article in terms of 3:2 pulldown for film based sources etc.2) DVD Resolution:
Correct for US and Canadian standards of television. 480 lines is the viewable area, however 525 lines total are displayed. Also true that HDTV displays can manage 1080i resolution.3) All are good choices, but if you can get past the boxiness of the Princeton, it offers the best picture according to my video expert.
Hope this helped.
