![]() ![]() ![]() ![]() | To answer the question, it's important to understand the difference between 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know as progressive scan (hence the 'p')The quality is like watching 30 photographic images a second on TV. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the 'i'), ie every other lines is displayed for 1/60th of a second and then the alternate lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously. ????: NamePros.com http://www.namepros.com/dot-mobi/331224-regged-720p-mobi-for-hdtv-reviews.html Most of the time interlacing works fine, but for fast moving images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' effect on-screen. Progressive scan signals don't have this problem and so are better suited to sports. ESPN puts it like this: 'Progressive scan technology produces better images for the fast moving orientation of sports television. Simply put, with 104 mph fastballs in baseball and 120 mph shots on goal in hockey, the line-by-line basis of progressive scan technology better captures the inherent fast action of sports. For ESPN, progressive scan technology makes perfect sense.' |

![]() ![]() ![]() ![]() ![]() ![]() ![]() | Everything is changing to 1080p right now. FullHD is 1080p only. HD means 720p or 1080i or 1080p. Bluray and HD-dvd are both 1080p and so is PS3 and i think xbox 360. Regular DVDs are only enhanced definition which is 480p but now most of them upconvert to 1080p. 720p and 1080i are both basically being phased out, except the new HD camcorders are using 1080i. |

![]() ????: NamePros.com http://www.namepros.com/showthread.php?t=331224 Nevertheless, there are many great websites on the Internet that were started up based on technologies/hardware that is now obsolete, and have adapted to their new surroundings. Take a peek at something like: pocketpcmag.com Pocket Pc's are pretty much a thing of the past now, but they've done an excellent job adapting to that. You could market your site as a review site for TV's which are 720p or higher resolution. | ||||
