LOGITECH HARMONY 650 USER MANUAL

Personal Video Recorder (PVR)

Contains an internal recorder and player that records and plays video without the use

of a removable tape or disc. Typically PVRs can pause, rewind, instantly replay, and

play slow-motion for live or recorded TV. Examples of PVR service providers are TiVo,

ReplayTV, UltimateTV, and Keen PM. Many cable and satellite providers also provide

PVR services and have PVRs included in some of their cable/satellite receivers.

Receiver

Also referred to as a tuner or a stereo receiver. A receiver can be any component

that receives or tunes broadcast signals, or AM/FM radio. Typically refers to the single

component that includes a preampliﬁer, surround processor, multi-channel ampliﬁer,

and AM/FM tuner.

RF (Radio Frequency)

Used by some remote controls to control devices because it doesn't have the same

line-of-sight restrictions as IR (infrared) signals.
