message: Why was 1080p removed from compatible video resolutions?  Component cables support 1080p, some HDTVs allow 1080p over component, but some do not. ~Michael
:Are you sure? The only thing you can get true (native) 1080p output from is Blueray and HDDVD and both of those players require HDMI cables to take advantage of the 1080p resolution. Perhaps there are some dated DVD players that upscale and output in 1080p over composite, but I wouldn't believe that until I see it. —The preceding unsigned comment was added by 130.63.18.177 (talk • contribs).

replies: text:  Popcorn Hour and clones also support 1080p over component (not composite!). From what I've read the reason blu-ray players do not support 1080p over component is that the blu-ray standard prohibits that (most likely due to lack of content protection).

Of course adaptors are used for BNC plug to RCA plug. —The preceding unsigned comment was added by 144.214.54.102 (talk • contribs) .
:Two problems: If you're referring to that flavor of "Component Video" that comes out of, say, a DVD player, then the components aren't Red, Blue, and Green (which are used by the VGA signals). Instead, two are "difference" signals (see YPbPr). Second problem: The VGA video may not include the sync (synchronization) signals in the video because VGA has completely separate wires for horizontal sync and vertical sync.

replies: text: Most European DVD video players output RGB component video (from the SCART connector) as well as YPrPb component from the RCA connectors.  Contrary to poular belief, for practical purposes neither has any advantage over the other.  YPrPb is what comes off the disk, but the display device requires RGB.  The former has to be converted to the latter somewhere, and it doesn't really matter where.  To be strictly accurate, if the signal has to be transmitted over very long distances, then YPrPb will suffer propagation problems because the Y component has a higher bandwidth and will therefore propagate more slowly. 20.133.0.14 10:25, 29 September 2006 (UTC)

message: One confusion I've had when setting up for HD has been that the capacity of an interface is not necessarily what that interface provides.  HDCP doesn't "like" Component Video, but that HDCP-enabled devices will still output to them, albeit at a lower resolution.  I'm not sure how this would fit into an article on Component Video, but it does affect the interface's capabilities, in practice.  Stevarooni 15:37, 2 November 2007 (UTC)

message: "Component video cables do not carry audio."
Isn't it more accurate to say that a component video signal does not carry audio? Component video cables are just RCA connected-cables, aren't they?

replies: text: Composite gives lower quality than component or RGB even at SD resoloutions for a number of reasons. As for whether the TV can do 480p i'd imagine that varies between individual TVs, best to either read the manual or try it (note i'm in europe where we used RGB scart rather than component for high quality SD so i've only personally seen component on HDTVs).

thread_title:  Merge to YPbPr? 

message: One thing confuses me that the article doesn't really explain. What is the point of YPbPr (rather than "pure" RGB) in component video? I can understand its use in composite and multiplexed signals where it makes sense to compress the two colour signals more than luma. However, surely in component form all three are allocated the same bandwidth- which I assume is the same bandwidth as R, G and B signals.
So why bother using component YPbPr over RGB at all- let alone the fact that it's apparently more popular? 88.105.112.128 (talk) 23:48, 9 April 2010 (UTC)
replies: text: One advantage is maybe that you could feasibly produce an image on a black-and-white monitor using the luma channel alone. A second maybe is that post-processing (i.e. adjusting lightness/contrast/saturation) is easier when the luma, chroma, etc. channels are already split ahead of time, as opposed to having to isolate (or convert to) these components after the fact (and most likely lossily) from the RGB signal. I'm just guessing though. SharkD  Talk  01:55, 16 November 2010 (UTC)

text: As far as connecting a DVD video player to a TV is concerned, one offers no advantage over the other.  YPbPr seems to have been adopted as the de facto standard in the United States (they could have easily adopted RGB instead).  Thus YPbPr is present on almost all consumer equipment.  European equipment also features an RGB connection (by virtue of the presence of SCART connectors).  SCART doesn't have to carry RGB, but most DVD players are capable of outputting it, and European TVs will generally accept it (automagically recognising it). 86.182.71.209 (talk) 17:18, 5 March 2011 (UTC)
thread_title:  YPbPr vs. RGB 

message: There is enormous confusion on this article about component video. People are commenting on this page who are mixing up the ideas of colour space and signal separation. If we accept the idea that colour space makes component video, well that makes all colour video signals component (even the ones which are also composite) as all colour video signals require colour space in some fashion or another. Nowhere is this confusion best illustrated than in the idea of digital component video.

thread_title:  Enormous Confusion over Component Video 

message: Can any of the three colored connections (either the red, green, or blue cable) be used in place of a single "composite" (yellow video) cable?  I realize that Audio will still need to be connected and that the user should just use a composite  single strand(yellow cable) instead of using a 3 strand component (red, green, blue) cable and only using one of these colors but I'm curious if this will work and if it matters which colored cable of the component cable I used for this connection.
:This is not a forum where you can ask technical questions or get tech support, it is a page for discussing discrepancies or (potential) changes to the article (see WP:NOTAFORUM). In future please refrain from asking such questions on talk pages.
:That said, the question is fairly trivial, so here goes. The colour is irrelevant - any RCA-to-RCA connector will work when connecting any RCA-type output/input, be it composite video, analogue audio, component video, digital coax audio or any other connection that uses RCAs. All an RCA cable is is a :coaxial cable with an RCA connector on either end. The colour-coding is only there so that it's more obvious to the user which cable connects to which port (if you connect an RCA into a composite connector but also have several other RCA cables connected to other ports (say audio and component), it's very easy to muddle them up and not know which was connected to composite without colour-coding).

thread_title:  RGBHV coloring 

message: The section about sync signals says the following (in other words):
* "Sync on composite" should not be confused with "composite sync."
* "Sync on luma" is pure sync signals transmitted over a wire otherwise used for luminance signals.
As far as I know, "sync on composite" and "composite sync" are not mutually exclusive - for instance, a SCART device switched to RGB usage will take the necessary sync from a pin otherwise used for composite video in.
I am unsure whether it separates the sync from composite video transmitted alongside RGB or uses pure composite sync. The point is, especially if the latter is true, that there is "composite sync on composite" - it is composite sync and it is transmitted over a wire also used for full composite video.
Similarly:
"Sync on luma" can refer to two ways of sending sync, in both cases it is composite sync. The first - a wire marked "luma" is used for transmitting composite sync to complement RGB. That makes no sense at all. And the second - S-Video or YPbPr use composite synchronisation combined with the luminance signal, and that is always true.
To prevent confusion, the information in the section - and also some "Composite sync" article I found lying around - should be clarified. Yet in what way, I am unsure.
If I am mistaken in my knowledge and opinions, feel free to correct me. Skloo (talk) 15:12, 4 November 2018 (UTC)
thread_title:  Types of sync 

message: I think something is wrong with this statement "RGB analog component video standards ..contain a lot of redundant data since each channel typically includes much of the same black-and-white image."
This is correct for black-and-white image, but wrong for the color, which is what RGB is used for. It's just a more or less direct interface of the RGB monitor. 
For black and white image, all three RGB channels are the same, and just like that YPBPR uses only Y channel, so they are the same in terms of redundancy and bandwidth. Luma-based monitor interface also often suffers from double signal conversion, and excess bandwidth for chromа, where the human eye is way less sensitive than to luma.
Тhis is all true for the composite video standards, not for high-frequency video transmission. Texdruk (talk) 19:59, 28 August 2023 (UTC)
