Here is a brief glossary of key terms you should know in order to understand the latest technologies used in high-definition television. What it does: The highest quality mode of high definition draws 1080 progressive lines onto your screen for every frame. You won't find 1080p content over the air or on cable or satellite, but it's the standard for Blu-ray and HD DVD. Why it's important: 1080p is the best picture you can get on a home screen. You may not own a Blu-ray or HD DVD player yet, but you won't want your television to seem out of date when you finally do buy one. Who has it: All seven of the LCD sets we reviewed for this article can display 1080p, as can the Panasonic TH-42PZ700U plasma. Just about every company making TVs today has some 1080p models, though most such models have relatively large screen sizes. 1080p is rare on 40- and 42-inch plasmas, and nonexistent on smaller sets of either type. What it does: HDMI provides uncompressed, digital bandwidth for both video and audio from a source (a DVD player or a DVR, for example) to your TV. HDMI 1.3 doubles that bandwidth and supports 10-bit, 12-bit, and 16-bit "deep color," rather than just the 8-bit color of other connections. By increasing the palette, deep color better approximates the analog range of color captured by motion picture film and the human eye. HDMI 1.3 also adds direct support for high-end audio formats like Dolby TrueHD and DTS Master Audio. (Most TVs won't support those formats, however; you're more likely to see them on home-theater receivers. Why it's important: In theory, both Blu-ray and HD DVD support deep color, and someday someone may release a disc that uses it. Who has it: Five of the twelve TVs we reviewed support HDMI 1.3: Philips's 42PFL7432D/37, Pioneer's PDP-4280HD, Samsung's LN-T4061, Sony's KDL-40V3000, and Toshiba's 42HL167. All new sets will have it in the near future.
