Composite Video Connection - A method to interconnect video devices (such as a DTV set-top box and the analog television) by sending the signal over a single cable. This method is suitable only for analog NTSC signals
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.
Decoder - See "codec." A device or program that translates encoded data into its original format (i.e., it decodes the data.)
VSB - " Vestigial side band." VSB is an analog modulation technique used to reduce the amount of spectrum needed to transmit information through cable TV, or over-the-air broadcasts.
SECAM - (Sequential Color And Memory standard) - This alternative to NTSC has 625 lines interlaced, 50 fields per second. It is used in the former USSR, France, and parts of Eastern Europe, the Middle East, and Africa.
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.
