A speaker setup that places one speaker above or below a television, two on either side of the display, and two beside or just behind the listener (standard surround). A subwoofer is to the front left of the listener. A surround system creates a more immersive, realistic sound experience-the more speakers, the richer the sound.

Interlaced (i) scanning
A method of displaying images from a video signal on a television screen. With interlaced scanning, half the vertical lines (odd lines) on the screen are filled in first, then the other half (even lines) for a complete image. Also see "progressive scanning".
An HP HDTV innovation that allows users to access, manage, and enjoy digital photos, music, TV, and video in one set-top device that combines the capabilities of HDTV, digital cable, and a dual-tuner digital video recorder. It includes an electronic program guide, a music information service, and an automatic update service that upgrades the device as new services become available.
Microsdisplay TV
A large-screen, cabinet television using DLP. The newest generation of microdisplay TVs are more lightweight and compact than their earlier counterparts.
Motion adaptive de-interlacing
Detects and compensates for motion in pictures, reducing contours and greatly diminishing visual noise without reducing picture detail.
A device that can record and play back television in digital format, as opposed to the analog format recorded by a VCR. Also called "digital video recorder."
PIP (picture in picture)
A television feature that allows you to view multiple TV channels simultaneously by creating one or more smaller displays within the larger television display.
POP (picture outside picture)
A television feature that allows you to view two or more (depending on the type of POP capability the set has) TV channels simultaneously by dividing the television display into halves.
Progressive (p) scanning
A method of displaying images from a video signal on a television screen. With progressive scanning, the vertical lines on the screen are filled in sequentially, rather than in two passes as with interlaced scanning. Also see "interlaced scanning".
A digital audio interface, most often used with an RCA connector.
