Talk:Composite video

From Wikipedia, the free encyclopedia

13:39, 11 July 2006 (UTC) In the 60's/70's some wag came up with some alternate words for the acronyms:

  • NTSC "Never Twice the Same Colour"
  • SECAM "System Essentially Contrary to the American Method"
  • PAL "someone please fill this in and check" "Perfection All Lines"? <-- "Picture at Last"

If I remember right it was heavily biased to PAL Archivist 00:55, Nov 15, 2003 (UTC)

Since the Yellow RCA connector is by far the most common connector, the term "yellow-plug video" has been suggested to help cut down on confusion between "composite" and "component" (which sound alike).

Samurai: what the hell does "commercial variations of video media." mean?

Why _IS_ composite referred to as RCA/BNC?

          Composite is referred to as RCA/BNC because those are the types of connecters used on the ends of the cable.
          An RCA plug is the common "yellow plug" video that is mentioned above.  BNC is an older style connecter that 
          attaches to coaxial cable.  BNC connectors can be found on old networking cards and all oscilliscopes.

BNC connectors are the professional choice and most professional video equipment will use BNCs for video input and output (composite, component, RGBHV, and in some cases even S-video); the RCA ("phono") connector is a poor connector in general, and regarded as particularly poor for video based on its electrical/shielding characteistics. BNC connectors are locking, mantain proper impedance and offer better shielding performance. Lincoln 69.17.11.103 17:35, 18 February 2007 (UTC)


Every piece of consumer equipment I've used in the USA in the past 25 years modulated the signal onto channel 2 or 3 (not 3 or 4), what am i missing?

I have never, ever owned a piece of equipment that modulated the signal into channel 2. Always 3 or 4. Liquidtenmillion 00:51, 15 April 2006 (UTC)

What is the normal frequency composite uses?

What is the typical and maximum equivalent resolution of video information carried by the CVBS format? 480 lines? Glueball (talk) 11:26, 13 May 2008 (UTC)

Unlike television channels, which are modulated onto an RF carrier, composite video is baseband. The signal ranges from 0Hz to about 4.5MHz. Television channels are about 6MHz wide, described variously as the lower end, the center, or the carrier frequency. US TV channel 2 is from 54 to 60MHz, for example, with the carrier at 55.25MHz.
