Universal Remote Control

A remote control that allows the operation of several components. Universal remote controls typically contain a series of preprogrammed codes that tell the remote which infrared commands should be sent for each button pushed. Good universal remote controls also feature learning ability and the ability to record macro commands. (See Figure G.19.)

Up Conversion

The process of adding information to a signal. For example, some home theater receivers up convert a composite video signal to an S-Video signal. Up converted video does not have the same quality as a video that originated at the resulting resolution. For example, many HDTVs up convert standard 480i cable sources to 480p by doubling every line. This up converted 480p image is not the same quality as an image that is natively 480p.
