Glossary continued

HD DVD (high-definition DVD) A next-generation optical disc format developed for high-definition video recording and rewriting. Types (red or blue laser) and storage capacity of HD DVDs vary. They include blue-laser DVD and Blu-ray disc.

HDMI (high-definition multimedia interface)

An uncompressed, all-digital audio/video interface between any compatible digital audio/video source, such as a set-top box, DVD player, and A/V receiver, and a compatible digital audio and/or video monitor, such as a digital television (DTV). HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable, and is backward-compatible with DVI.

HDCP (high-definition content protection) An encryption in high-definition signals that prevents unlawful duplication. HP’s HD demo tapes have HDCP encoded.

HDTV ATSC tuner An internal or external over- the-air tuner that receives high-definition television signals. Also called “ATSC HD tuner.”

I

Integrated HD An HDTV that has a built-in high-definition receiver/tuner.

Interlaced (i) scanning A method of displaying images from a video signal on a TV screen by filling in every other line (the odd lines), and then filling in the other lines (the even lines), so only half of the set’s lines are “firing” at a given time. Interlacing allows for greater resolution at lower bandwidth, but it can produce flicker if you’re watching sports or other content showing rapid movement.

M

Microdisplay TV A large-screen television using rear projection technology. The newest generation of microdisplay TVs are more lightweight and compact than are 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.

N-O

Optical cable A digital connector that carries information optically rather than electronically, which renders it unsusceptible to electrical interference.

Over-the-air HD programming Requires TV owners to have an HD antenna and HD-capable TV, and live in an area where digital television is broadcast.

P

Personal video recorder 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.

J-K-L

Low-angle interpolation A corrective feature in HP TVs that smoothes out the “staircase effect” caused by viewing at certain angles.

Lumen The unit used for measuring light output, expressed in “candelas per square meter,” or cd/m².

Progressive (p) scanning A method of displaying images from a video signal on a TV screen by filling in all of the vertical lines sequentially, rather than in two passes, as with interlaced scanning.
