Yes, that's correct. Negative or super-white values of R'G'B' can't happen unless a scheme like 1361 is adopted. SCART is perfect until then, and would still be fine as long as there are no clippers in the R'G'B' signal paths and a colorimetrically correct linear matrix (in the linear RGB signals) is included to convert signals to the display primaries (if they are different from those of the transmission system). ----- Original Message ----- From: "John Shutt" <shuttj@xxxxxxxxx> To: "OpenDTV" <opendtv@xxxxxxxxxxxxx> Sent: Thursday, January 13, 2005 5:29 PM Subject: [opendtv] RGB mania > All, > > I have read with great interest all of the responses regarding negative RGB > values, color gamuts that exceed current video specs, and the wonders of > negative and superpositive values of RGB. > > However, as fascinating as all this information is, and I am not being > sarcastic, it does not address my original rebuttal to Tom McMahon's > assertion that RGB was unacceptable as a connection between a DTV STB and a > display, ala SCART, when compared to a component connection.
