NTSC - (National Television System Committee technical standard) - This is analog TV invented in 1946. NTSC has 525 lines (483 visible) interlaced, 60 fields per second. This standard is in use in North America, Japan, South Korea, Burma, Taiwan, the Philippines, and much of South America.
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.
LNB - (Low Noise Block converter) - An LNB can be found at the focus point of a dish antenna. It is a low noise amplifier that also converts the signal to a lower frequency. (The original higher frequency would not travel very far in ordinary coaxial cable.)
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
Metadata - Informational data about the data, included in a signal's data stream.
DTVLink - This logo is on equipment that has IEEE 1394 and DTCP.
DirecTV - (see DBS)
