Resolution - The level of resolution directly affects picture quality. The higher the resolution, the more picture detail there is. Many things affect picture quality, including number of bits, pixel count, format, receiver quality, cameras, lenses and lighting used for live or taped programming. Resolution is measured by the number of pixels displayed. One of the high-definition picture formats is composed of 1080 active lines, and each line is composed of 1920 active pixels. Therefore, each frame has over 2 million (1080x1920=2,073,600) color pixels creating the image. By way of contrast, today's typical analog television is roughly equivalent to 480 active lines, with each line holding about 440 pixels. So, each frame has a little over 200,000 color pixels in use creating the image.
Digital Cable - A service provided by many cable providers, digital cable offers viewers more channels. Contrary to many consumers' beliefs, digital cable is not the same as High-Definition Television or digital television; rather digital cable simply offers cable subscribers the options of paying for more services. Digital Monitor - DTV monitors are televisions that can display a digital signal but lack an integrated tuner (unlike an integrated digital set), and thus cannot receive a digital broadcast signal without an additional set-top box.
PCM - (Pulse Code Modulation) - This 2-channel digital audio standard is simpler than Dolby Digital.
Progressive Scanning - A system of video scanning where lines of a picture are displayed consecutively (unlike interlaced).
Progressive Scanning - Some HD televisions use the "progressive" method of scanning, in which the whole picture is transmitted and presented on the screen in one pass. The resulting image is thus remarkably free of flicker and motion artefacts, appearing more "life-like". Some display types, such as LCD, plasma and DLP are inherently of the progressive scan type, while CRT's may be scanned progressively (as in computer monitors) or interlaced.
DVI - (Digital Visual Interface) - This connector conveys HDTV image scanning signals in binary data form. The data rate is very high (1.65 Gb/s). Binary data is preferred by monitors that are not CRTs. DVI comes with a decryption option called HDCP which will decode encrypted programs such as first-run movies.
D/A - Conversion of digital signals to analog signals. Most set-top boxes decode the digital signals broadcast and then convert them to analog signal for interconnection to the display device.
