VGA - a 5-wire standard interface, originally for computer monitors, now common for HDTV monitors. Usually the 5 wires are in one cable. The connector can be either a 15-pin connector or five BNC connectors. The signals are usually red, green, blue, horizontal sync, and vertical sync. But Y, Pr, and Pb can replace the colors.

Progressive scan - This is the opposite of interlaced scan.

AC-3 - (see Dolby Digital 5.1)

MMDS - Multichannel, Multipoint Distribution System. A wireless cable system capable of being encoded for pay-per-view and subscriber services.

DLP (Digital Light Processing) - A technique in which the displayed image is produced by an array of dynamic micro-mirrors formed on a chip, each reflecting some of the light source to form a pixel on the screen. Each micro-mirror controls the level of the light sent to the screen for its pixel. Resolution is set by the size of the mirror array and versions suitable for wide-screen HDTV are now in production for uses in both front and rear projection televisions.

AACS - Advanced Access Control System. A computer specification for guarding next-generation optical-media content created by the film, electronics, and software industries.

Encryption - The process of coding signals so that a specific code or key is required by the viewer to recover the data so encrypted. Without this key, the data is meaningless. Encryption is used to provide conditional access for private television services.
