HD televisions and de-interlacing

Glossary continued

D

Digital light processing (DLP) A Texas Instruments display technology that uses a Digital Micromirror Device (DMD) to create and project vibrant, high- definition images via either television or a projector.

De-interlacingA feature that improves picture quality, producing a film-like richness. Sixty frames per second are shown as opposed to the standard 30 frames per second. Also called “line doubling.”

Digital coaxial cable Carries a multi-channel audio signal between digital or electronic devices, separating sound into speaker-specific signals.

Dark video enhancement Enhances details in dark scenes.

Digital tuner A set-top or built-in television tuner that receives digital television signals. Also called “digital receiver.”

Dolby Digital A form of digital audio coding

that efficiently encodes sound to a digital format, especially when multiple audio channels are required.

DTS (Digital Theater System) Digital Surround

A surround sound format (5.1, 6.1, or 7.1), similar to Dolby Digital standard, that features five to seven discrete (independent) channels, plus a channel for low frequency effects. See “Dolby Digital” and also “Surround Sound.”

E

Electronic program guide A program menu on HP entertainment products, such as the Digital Entertainment Center and Media Center PC, that displays chronological, and automatically updated, program listings.

HD televisions (see illlustration above) Any TV set with native support for at least 720p is considered an HDTV. But will HD programs viewed on a 1080p set look better than they do on 720p mod- els? The answer depends on the type of HD program. No HD shows are currently broadcast in 1080p; some are recorded in 720p, others in 1080i. 1080i content can be broadcast in 1080p using a de-interlacer. A 720p set de-interlaces the 1080i image and then scales down the 1080 hori- zontal lines to 720 lines; a 1080p set only has to do the first step, so it should produce a better-look- ing image. But 720p content is likely to look better on a natively 720p set than on a 1080p model that has to scale the image up.

HD-Built-in vs. HD-ReadySome HDTVs (HD-Built-in) have a built-in tuner to receive local high-definition broadcasts, and are considered true HDTVs.

Sets without an integrated tuner are “HD-Ready” and need a set-top box to decode the high- definition signal.
