	Composite video - Wikipedia, the free encyclopedia
		Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier.
		Composite video is often designated by the CVBS acronym, meaning either "Color, Video, Blank and Sync", "Composite Video Baseband Signal", "Composite Video Burst Signal", or "Composite Video with Burst and Sync".
		It is commonly believed that composite video is a retronym coined after the introduction of S-video.

	Composite video (Site not responding. Last check: 2007-10-30)
		Composite video is the format of an analog television signal before it is modulated onto an RF carrier.
		Composite video can easily be directed to any broadcast channel simply by mixing it with the proper RF carrier frequency.
		In the United States, the composite video signal is typically connected using an RCA jack, normally yellow (with red and white for left and right sound).

	Method and apparatus utilizing look-up tables for color graphics in the digital composite video domain - Patent 5402181
		Composite systems represent the image using a single data stream, usually 8 bits wide, which is formed by passing the NTSC composite video signal through a single analog-to-digital converter without any prior decoding.
		In the NTSC video signal, color is presented by a 3.58 MHz amplitude and phase modulated subcarrier which is mixed with the luminance, or fl and white portion of the image.
		The video signal is also fed via 48 to the sync stripper 53 which separates the vertical and horizontal sync pulses (VS and HS, respectively) from the video signal as well as an even/odd field signal 54 which is fed to the field counter 57 via 54.

	Digitization of video signals - Patent 4825286
		The sum signal is sampled and digitized at a sampling frequency which is at least twice the audio carrier frequency and is more than three times the frequency of a color subcarrier in the composite video signal, and is not related thereto.
		This invention relates to the digitization of video signals, and in particular is concerned with the conversion into digital form of composite video television signals in a manner which is particularly convenient for transmission via a transmission network, which may in particular comprise an optical fiber transmission path.
		Applied to a television signal, the analog video signal may be constituted by a composite video signal and the second signal may be a carrier signal frequency modulated with an audio signal.

		The composite color video signal, often called the Color Video, Blank, and Sync (CVBS) signal, is the sum of Y and C, is shown in Figure 3.
		The analog composite video signal is defined as a voltage source with an output impedance of 75 Ω.

	Video Engineering Primer
		To see the various elements of the composite video signal two special test oscilloscopes are used - the waveform monitor and the vectorscope.
		Signals that are outside of this range lose all detail so that if a light colored face is at or above 100 units, it will be washed out.
		If, however, you are not changing the video signal because you are working with a basic editing system without any additional equipment, then except for degadations caused by generation loss, the colors and luminance of your edited tape should be the same as your source tape.

	AN4 - Common Video Signal Standards
		The composite video signal was designed primarily for broadcast television and not ideally suited for industrial and higher performance applications.
		A primary problem with composite video is that it suffers from a phenomenon called "cross color".
		Contrast this to the single cable of the composite signal or the dual cable of the S-Video signal.

		A composite video signal is the kind used by a television set.
		The Video Data: The Video data is an analog signal between zero and one.
		The Horizontal sync signal is asserted a small amount of time after each single line is recieved, thus allowing the reciever to adjust any timing glitches prior to capturing the next line.

		In composite video, there is not only a significant loss of overall sharpness, but also fringes along the edges of strong colors.
		YUV and RGB component video are capable of carrying a pixel-perfect or near pixel-perfect signal, with overall high sharpness and full color resolution.

		It is usually in a standard format such as NTSC, PAL, or SÉCAM.
		Composite video can easily be directed to any broadcast channel simply by modulating the proper RF carrier frequency with it.
		This may then be converted to RF with an external box known as an RF modulator that generates the proper carrier (often for channel 3 or 4 in North America).

	Tomi Engdahl's Video Signal Standards and Conversion Page
		Composite video signal is the most often used video signal format in TV broadcasting industry and it is used anywhere from TV camesras to TV broadcasts upto consumer video equipment interconnections.
		Composite video signal is most often transported using one 75 ohm coaxial cable terminated with RCA or BNC connectors so that center pin carries the signal and the outer shield of the connector is signal ground.
		Generally telecined PAL signal does not cause problems in computer processing, but is some cases where one field of video is shifted by a frame, you get a video signal which looks okay on an interlaced display (television), but it produces interlacing artifacts on a computer monitor and when video is digitized.

	Video Signal Formats
		RGB, Component, S-Video and Composite are terms that are commonly heard, but what do they mean and which one should you use.
		Cr and Cb are two signals containing matrixed colour information to extract the Red/Blue from the picture information in the Y signal.
		Composite Video and usually Audio as well, modulated to a much higher frequency but can enable multiple signals to be distributed over the same cable by choosing different carrier frequencies.

		The equipment which outputs RGB or composite video signal, the composite video is available on pin 19 at the female connector on the back of the signal sending equipment.
		The wiring needs an sync amplifier circuit, because the 0.3Vpp composite sync signal which is included in normal composite video signal is not generally stron enough for the sync inputs used in video projectors.
		Composite sync to HSYNC and VSYNC converter Sync separation is a process quite often needed in video technology, but it is a little bit hard to find a chip which especially made for that.

	S-video to composite video
		The other three pins can have then some extra signals which are not part of S-video (usually some pins of those carry composite video and some control signals, but the use of those three extra pins vary quite much).
		A typical problem that causes fl and white video instead of color is incomatible video standards on the signal source and the receiver.
		If your video signal source (for example PC video card TV output) puts out NTSC video but your TV is designed to handle only PAL standard you get usually fl and white image, and with some devices video signal does not sync at all.

	Composite Video with Screw Terminals
		Our Composite Video over CAT5 Balun allows a single composite video signal or each of the three component video signal (Y, Pb, or Pr) to be transmitted via cost-effective unshielded twisted pair (UTP) cable.
		The Component Video Balun is compact enough to allow three (3) units to be connected side by side on the back of the component video equipment.
		Since the bandwidth of the component video signal is relatively low compared to high speed data, using Cat6 instead of Cat5 will probably not yield a perceptable difference at short distances (under 500 ft).
