Analog TV - Analog technology has been in use for the past 50 years to transmit conventional TV signals to consumers. "Standard" television broadcasts in analog TV. Analog signals vary continuously, creating fluctuations in color and brightness.
HDTV - (High Definition TV) - A TV that displays 1280x720 pixels or better.
Interlaced Scanning - Some HD televisions and most conventional televisions use the "interlace" method of scanning, in which the picture is transmitted and painted on the screen in two passes. In the first pass, every other line is painted and in the second, the lines in between. Some display types, such as LCD, plasma and DLP cannot display directly images transmitted as interlaced signals and must convert them to a progressive format prior to their display.

PSIP - Acronym for "Program and system information protocol", an ATSC DTV specification that enables a DTV receiver to identify the program information and to create on-screen electronic program guides and content advisories.
BNC connectors. These common RF connectors are sometimes found on VGA cables in place of a VGA connector. They employ a quarter-turn twist-lock mechanism.
Downconvert - The process which reduces the number of pixels in the scanning format used to represent an image, so that it may be reproduced on a display of lower resolution, such as a conventional television. For example, an HDTV image may be downconverted to an SDTV or NTSC image, but in the conversion significant detail information may be lost.
