In video, a field is one of the many still images which are displayed sequentially to create the impression of motion on the screen. Two fields comprise one video frame. When the fields are displayed on a video monitor they are "interlaced" so that the content of one field will be used on all of the odd-numbered lines on the screen and the other field will be displayed on the even lines. Converting fields to a still frame image requires a process called deinterlacing, in which the missing lines are duplicated or interpolated to recreate the information that would have been contained in the discarded field. Since each field contains only half of the information of a full frame, however, deinterlaced images do not have the resolution of a full frame.
In order to increase the resolution of video images, therefore, new schemes have been created that capture full-frame images for each frame. Video composed of such frames is called progressive scan video.
Video shot with a standard video camera format such as S-VHS or Mini-DV is often interlaced when created, whereas video shot with a film-based camera is almost always progressive. Free-to-air analog TV was mostly broadcast as interlaced material because the trade-off of spatial resolution for frame-rate reduced flickering on Cathode ray tube (CRT) televisions. High-definition digital television (see: HDTV) today can be broadcast terrestrially or distributed through cable system in either interlaced (1080i) or progressive scan formats (720p or 1080p). Most prosumer camcorders can record in progressive scan formats.
Field may refer to:
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.
Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.
Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.
Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

Did human extraterrestrials visit Earth -- and predict a Golden Age will culminate in the year 2012, freeing us from evil, fear and doom? Did the founding fathers of America inherit this prophecy -- and encode it directly into the Great Seal of the United States? Why is there a pyramid with an eye inside a glowing triangle? Is Novus Ordo Seclorum quoted from an ancient prophecy text -- the greatest and most secret treasure of the Roman Empire -- predicting that humans on Earth will transmute into "light beings" and achieve Apotheosis -- where Man becomes God -- and the 'Gods' themselves return?

I'm back guys. Been extremely busy even after school finished up. Working an internship in Philadelphia 5 days a week so that's eating up most of my time. I've had to move my lawn care work to nights and weekends but I've been getting through it. This new 316 tractor has been getting LOTS of use already and has been a great investment, and I know how eager everyone has been to see a video of it, so here it is. A friend of mine from another town needed her back field mowed for a party the next night. It was a farm at one point but over time, weeds overtook the field and it just became part of the lawn. It was probably about 5 acres of grass, until severe thunderstorms and minor tornadoes hit southern New Jersey and wiped out lots of huge trees. The big oak trees on the property were uproo...
