Jargon Buster! Lesson No. 6

We're back again with more tidbits for you to munch on. So warm up your jaw and chew on this:

DLP (Digital Light Processing)
A remarkably clever projection technique that bounces light off a microchip covered in millions of tiny mirrors, each controlling the colour of an on-screen pixel. The angle of the mirror determines the projector's video output.

Dolby Digital
A multi-channel surround sound format used on movie and DVD soundtracks. Normally stores five channels of audio and a subwoofer track (5.1). Hi-def versions Digital Plus and True HD support more channels and have higher sound quality. They can be found on Blu-ray and HD DVD discs.

The directional control found on console game pads, some mobile phones and PMPs. It's used to navigate menus and often controls player movement in games.

1. In computers, the software that makes hardware devices work.
2. In speakers, the cones that produce sound. Tweeters produce high notes, mid-range drivers produce voices and instruments, and woofers produce bass.

DRM (Digital Rights Management)
Copy protection as applied to digital music and video. Usage is typically available only to the content purchaser. MP3 does not support it, but most other formats do; PlaysForSure is Microsoft's own DRM.

These speakers, thanks to their single-driver arrangement, fire music at you like a sonic death ray for a pin-sharp stereo image

Did the tidbits sate your hunger for knowledge? Probably not. But don't worry, we have more tidbits coming your way in the next few entries.
