Standard vs. High Definition
SD or standard definition refers to the pixel ratio of standard broadcast television video. It is 720 pixels wide by 486 pixels high. A pixel is a rectangular dot that can be addressed to display any color. It is ideal for an image to be broadcast in the format that it was created in. If you have something that was created at 100 x 100 pixels and then broadcast it at 720 x 486 pixels it will look pixilated or jagged and rough.
HD or High Definition is 1920 x 1080 pixels in a wide screen format or 1440 x 1080 pixels in 4:3 format. It has approximately 6 times the pixel information per frame as standard definition. Obviously, it takes more robust and therefore more expensive equipment to display high definition images properly.
It should probably be noted that most projectors display an image that is 1024 x 768 pixels. So either way the image will have to be up converted or down converted to display at all. This means that a machine processes all the images and runs them through a digital template very quickly so that the images can be projected. We have projectors that will display higher resolution and therefore give a true HD image if that is what your event requires.
