Component Video
A Component Video Signal is basically a video signal that is split into two or more components in order to transmit the information. Component video offers better picture quality than composite video. Three cables are required for transmitting the information and three RCA or co-axial jack forms the interface of the component video which is one of the high-end video interfaces being offered in today's equipments. Audio data is not carried by the component video cables and so, additional audio cables are required.
Component video is capable of carrying the wide range of signals such as the 480i, 576i, 480p, 576p, 1080i, 1080p. Analog component video is used for the most of the consumer level applications whereas digital component video is still gaining popularity in both home-theatre and computer applications.
The three cables used in the analog interface are used to preserve the different elements of the video signal. The different RGB analog component video standards use a large bandwidth to carry the signal and these standards do not impose any sort of limit on the resolution or the color depth. The component video interface is either marked as Y Cr Cb or it is marked as Y Pr Pb. However, both are analog and they mean the same thing for consumer level equipments. Usually, additional synchronization signals are sent along the images and these signals can be embedded in the blanking period of one of the components or they can be transmitted on separate wires.
DVDs use component video whereas laserdiscs, VHS tapes and regular television signals use composite video. A device with component video output connected to another device with component video input will provide better picture quality when compared to the devices using composite video connections.

- Composite Video
A Composite Video is analog television signal's format before a sound signal is combined with it and modulated onto an RF carrier. It is the most common type of video interface that is used for receiving and sending an analog video signal to and from a television set. A CVBS (Composite Video with Burst and [...]...
- Digital Audio-Video Cables
For audio and video lovers the good news is that there are many types of digital audio and video (A/V) cables to choose from. Usually these cables are made from either copper wire that is shielded and housed in strong casing or fiber optic usually made from clear plastic which uses pulses of light to [...]...
- S-Video
S-Video is an abbreviation for Separate Video and is also known as the Y/C. it is an analogue video signal that carries the video data as two separate signals; these signals are luma (brightness) and chroma (color). The S-Video can be thus contrasted with composite video, which carries picture information as a single component, albeit [...]...
- How to Download a Video from a Camcorder to a Computer
The process of downloading a video from a camcorder to a computer depends on whether the camcorder is digital or analog (old-style camcorder that uses tapes). For an analog camcorder, install a signal digitizer card in the computer, which is fairly common with today’s readily available off-the-shelf TV tuner cards. This card converts the analog [...]...
- Video Multiplexer
Video applications often require you to manage several different signal sources. A video multiplexer is a device that helps you put recordings of signals from multiple security cameras on one cassette. It handles several video signals simultaneously. Video multiplexers can split a monitor into various display areas and vice versa, i.e., combine output signals from [...]...
