RCA Connector

An RCA connector is a type of standard, low-level signal connection termination or connector. RCA-type cables are used for connecting many types of video and audio components.

RCA V-Port

The RCA V-port is a jack that enables you to directly connect an X-box to the TV. This jack comes only on RCA TVs.

Rear Projection Video Display

Rear projection is a type of video display. With the rear projection screen, light hits the screen from behind and shines outward instead of hitting it from the front and bouncing back into the room.

Most rear projection televisions contain at least one tuner and many also feature picture-in-picture and other enhanced features. Rear projection displays are easy to set-up and cost less than front projection systems.

Receiver

A receiver is a component (either audio or video) that receives and decodes a video or an audio signal (e.g., satellite receivers, HDTV receivers, audio receivers, etc.).

Refresh Rate

The refresh rate, or vertical scan rate, is the number of times a video display can paint an entire image with a video signal. The standard refresh rate for video (television, DVD, VHS, laserdisc) is 60 Hz. This means that the display redraws the image 60 times in a second.

The maximum vertical resolution of a video display (the number of horizontal lines drawn) can be determined by dividing the horizontal scan rate by the refresh rate (the vertical scan rate).

Resolution

Resolution refers to the number of elements (pixels) used to create an image. In digital video and audio, resolution refers to the number of bits of information that recreate a signal.

Higher resolution provides higher quality.

RF (Radio Frequency)

Radio frequencies are used for broadcasting video, audio, satellite, cellular phone signals, radio telescopes, emergency beacons, and much more. Located above the radio frequency (at higher frequencies) is the infrared electromagnetic spectrum, and above that is the visible light spectrum.

RGB

RGB stands for the three additive primaries – red, green and blue – that combine to form the color spectrum .
