raster - On a CRT television, the overall area scanned by the electron guns.

rear projection - TV system where the picture is projected onto the rear of a translucent screen via a series of mirrors and viewed as you would an average television.

red push - Tendency of the color decoder in many TVs to accentuate the color of red compared to blue and green. Red push is typically introduced intentionally to compensate for an overly blue color temperature.

resolution - The sharpness of a video image, signal or display, generally described either in terms of lines of resolution, or pixels. Visible resolution depends on both the resolution of the display and the resolution of the video signal. Since video images are always rectangle-shaped, they are described with both horizontal and vertical resolution.

RF jack - Radio frequency jack. Audio/video connection commonly used to bring signals from antennas, cable systems, and satellite dishes to components with some type of tuner, such as cable boxes, cable modems, HDTV set-top boxes, VCRs, satellite receivers, TVs, and so on. It can carry video and stereo-audio information simultaneously. When used to connect two components, such as a VCR and a TV, RF provides the lowest video quality of any connection. RF cable connectors usually screw or push onto the jack. Also called F-type, 75-ohm, or coaxial connections.
