Q349. - (Topic 6)
Which of the following cable types carries an analog video signal across three separate physical channels?
A. Component
B. RCA
C. DVI-analog
D. VGA
Answer: A
Explanation:
Video connections use many of the same connectors as analog and digital audio. Pro video applications generally use XLR or BNC cables, whereas consumer video equipment often
uses RCA phono plugs. Phono plug connections can be either composite or component video. Composite video carries the video signal on one cable, whereas component video provides the complete signal on three separate cables, one for each of three color channels. Specialized video connectors include S-Video (also called Y/C) connections, which are transmitted on 4-pin mini- DIN connectors to provide greater color depth than composite video. There are also unique connectors for new high-definition digital video formats like HDI and DVI.
