I really doubt Sony Creative Software invented this studio levels thing. When this system is not used and the video signal uses all code values from in 10 bit it is called full swing or extended range.

Incorrect color bars will cause a sub master to be rejected by quality control checks. I blame microsoft with their video for windows: The first edition of the standard was approved in This page was last edited on 11 Juneat The standard has been revised several times in its history. I completely answered the wrong question In practice, this conversion is rarely performed and such a conversion would create a liability for post production facilities as they would need to ensure that the color bars on all the new masters are redone.

From where is this information? Correcting for differences in the primaries would cause the resulting color bars on the converted tape to be inaccurate. It might only exist to make the old analog formula continue to work out correctly. It is basically a hack, using the limited range and gamma function of BT. Video captured as progressive can be transported with either progressive transport or progressive segmented frame PsF transport.


BTW the standard allowed for bit quantization right from the very beginning, so saying “” is a simplification, but we all know what is meant.

Can you give a source? The values 0 and are used to encode the sync pulses and are forbidden within the visible picture area. I bt.01-5 you all for your answers! This question is important for me from bh.601-5 theoretical point of view. I’m not sure about the RGB question. And bllack is 0white is I do not understand this contradiction.

Its edition 7, referred to as BT. Views Read Edit View history. I can not find a a definition for this color space. List of color spaces Color models. HDTV according to Rec.

Similarly, code values through provide headroom and can be used to accommodate transient signal content such as filter overshoots.

Algorithms and Interfaces” by Charles A.

The Cb and Cr samples are unsigned and use the value to encode the neutral color difference value, as used when encoding a white, grey or black area. Again however, as foxyshadis has said post 2don’t use limited-range RGB without good reason.


Besides the range the difference between it and sRGB is the length and slope of the liner section near black in the gamma curve. And I have found something else.

Code values from and from are reserved as footroom and headroom. It seems like your question has been answered several times over already.

You would think that 0 represents pure black and represents pure white. Commons category link is on Wikidata Commons category link is on Wikidata using P In coverage of the CIE color space the Rec. He is based on data of standard that I quoted above. Wikimedia Commons has media related to Chromatic diagrams. But the “hack” is defined by the standard REC. Do I understand correctly?

It was not a question. It is the same at the top end: However, in practice it is output display referred with the convention of a 2.
