High Definition Video (White Paper)
By now everybody has heard of HD video and many people have gone out and purchased that big LCD or plasma HD television for their home or office. Yet, many people don’t really know the difference between SD (480i), ED (480p), and HD (720p, 1080i and 1080p.)
On the business side, people who use video are wondering about HD and how to make it work in their television commercials, on their website, and for long-format video.
Resolution Basics
Most people understand that better picture quality is primarily created by more lines of resolution. (We’ll explain lines of resolution later on.) But there’s more to the story than just that.
There are actually two resolutions that come into play with HD. There is the source resolution–where the video is coming from (cable, broadcast, DVD, BluRay, etc.) And then there is also the monitor’s resolution.
(Please note, when we refer to monitor, you can substitute the word TV. When we’re talking about resolution, there is no difference.)
