Talk:YPbPr

message: Y means luminance, but what do Pb and Pr mean? thanks, --Abull 20:52, 17 Jan 2005 (UTC)
replies: text: The 'b' and 'r' mean 'blue' and 'red' respectively.  The 'P' stands for 'Parallel', which had something to do with the actual electrical connection when the standard was first made, but you can safely assume it doesn't stand for anything in particular other than to differentiate it from YCbCr 64.121.2.24 21:29, 5 May 2007 (UTC)
replies: text: What the P (and the Y for that matter) actually stand for should be added to the article. I've been googling for a while and have not been able to find out. The most convincing argument I found was that is stood for 'Purplish'. This is the only place I've seen it claimed that it stands for 'Parallel'. A reliable source needs to be found for the abbreviation and this should be added to the article.
The article calls Y the luma component, but other articles differentiate between luma (Y') and luminance (Y). Is the article incorrect?DB10099 (talk) 10:25, 15 May 2008 (UTC)
thread_title: What are Pb and Pr?

thread_title:  B-Y R-Y Y 

message: The entry doesn't state why component is thought of as the best type of analog connection between video devices. How does it compare with analog RGB connectors? --24.249.108.133 16:08, 1 March 2007 (UTC)
thread_title:  Why is component good? 

message: My understanding is this scheme was originally invented to implement broadcast color TV as an addition to but without altering or impacting the original black-and-white signal being received by millions of B&W TVs.  In fact the Y-signal is actually the legacy black-and-white TV signal and the other two were added for (now obsolete) analog color TVs to "chromatize" the B&W picture.  This may be demonstrated on some monitors by connecting only the Y component cable from a video source to the monitor's component video inputs producing a B&W version of the source video.  My recollection is this scheme was proposed by RCA and/or adopted back in the late 1940s or early '50s.  An alternative proposed by another TV giant (CBS?) was rejected because it would have required an entirely new set of frequencies/signals for color TV. --Jmangross (talk) 20:21, 16 July 2009 (UTC)
replies: text: The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section. 
The result of the proposal was no consensus to move.--Fuhghettaboutit 01:56, 16 April 2007 (UTC)
thread_title:  What about historical usage? 

message: OK, I don't think that there is much information about how YPbPr is different from YUV (whereas there is some mention in the YCbCr article).  I can get that YPbPr is used for analogue and YCbCr is used for digital, but then there are other questions that need asking.  Such as: 
* Does YPbPr use the same colour space as YCbCr?  If so, then the same graphics in the YCbCr article can be used here as well.  If not, then how is the YPbPr colour space different from YCbCr, apart from the obvious "one is analogue & one is digital"?
* How is the YPbPr colour space similar to YUV?  How is it different?
* Along the same lines, for comparison sake: How is the YPbPr colour space similar to YDbDr (the space used for SÉCAM) and NTSC's YIQ colour space?  How is it different from them both?
* How can one differentiate between YPbPr and YUV?
* Hypothetically, is it possible to have an analogue colour TV system invented which only uses the YPbPr colour space?
Granted, these are the questions that a non-specialist could ask and which should be addressed in the article, but I would hope that they would be answered here in the talk page first - just because I'm curious.  --Daniel Blanchette 01:52, 20 October 2011 (UTC)
replies: text: "Does YPbPr use the same colour space as YCbCr?" Yes. "YPbPr colour space similar to YUV?" I updated YCbCr article about that 1/2 is used. All other questions are not important. 2A00:1370:812D:178D:D87F:3075:AE6C:AB53 (talk) 08:50, 15 April 2021 (UTC)
thread_title:  YPbPr vs. YUV? 

message: Please make it clear whether the red green and blue cables actually conduct those specific individual colors separately because this article dose not state that specifically but seems to hint that the colors are not representative of the mixed colors amongst the respective colored wires (and I don't know and can't tell from this article).  — Preceding unsigned comment added by 71.163.183.71 (talk) 09:49, 5 January 2013 (UTC)
thread_title:  Please make it clear whether the red green and blue cables actually conduct those individual colors 

message: I've been told that Composite Video and S-video generate color in NTSC at a bandwidth of 3.58 megahertz with a horizontal resolution of 120TV lines per scan-line. In a digital resolution that would be 160x480 for color resolution. What I want to know is how much more bandwidth do you get with Y-Pb-Pr component video, after all component video produces color at a higher resolution than composite video and s-video. Does anybody know what the horizontal resolution is for Component Video color? I also want to know if the horizontal resolution stays the same when you pump HD resolutions over component video such as 720p,1080i, and 1080p. I just wish this was explicitly stated in Wikipedia article for this analog video format.  TommyMunoz2002 (talk) 22:21, 22 July 2022 (UTC)
