DBS (direct broadcast satellites) - These satellites are powerful enough to be received by an 18 inch dish. They use Ku-band frequencies. Companies that provide DBS services to consumers in the U.S. are DirecTV and Dish Network. Canadian DBS providers are Star Choice and Bell ExpressVu. Also called DSS.
Reverse 3 - 2 Pull-Down - DTV material originating on film at 24 fps is converted to the 30 fps of DTV by repeating field or frames, resulting in some motion artefacts. Some film presentations remove these repeated images before transmission and send a signal to the television causing it to process (termed Reverse 3 - 2 Pull-Down) this material appropriately to make it suitable for display. In this way, the displayed material closely matches the original film quality, avoiding the motion artefacts.
Barn Doors - A term used in television production to describe the effect that occurs when a 4:3 image is viewed on a 16:9 screen. When this happens, viewers see black bars on the sides of the screen or "barn doors."
Fresnel Screen (projection TV) - Helps balance out the light of the image across the screen. Without this screen, there would only be a centre screen bright spot. This screen receives the initial light image from the mirror and is made up of grooves, not unlike the grooves on an original LP record, in a circular pattern.
Parental Lock - Many movies on DVD are available with variable ratings capability. According to your parental lock setting, the movie will skip over particular scenes, playing the version that you choose from among those available on the disc. This feature can be set by remote, with a password, to prevent the settings being changed without permission.
Component Video Switching - Component inputs on a receiver let you switch between multiple component video sources and is compatible with Progressive Scan Video.
Auto Repeat - Allows the VCR to automatically rewind and begin playback when the a tape finishes playing.
