Anything under 16 is called super black and anything over is superwhite. In legal levels, video range or studio-swing, however, black is placed at code value 16 and reference white is at in 10 bit.

The standard has been revised several times bg.601-5 its history. However, in practice it is output display referred with the convention of a 2. Eight-bit code values from 1 through 15 provide footroom, and can be used to accommodate transient signal content such as filter undershoots. It is basically a hack, using the limited range and gamma function of BT.

Rec. – Wikipedia

And bllack is 0white is I do not understand this contradiction. Interestingly, in what cases is used the: I’m not sure about the RGB question. Bt.601- category link is on Wikidata Commons category link is on Wikidata using P It was not a question. This means that unlike Rec. From Wikipedia, the free encyclopedia.

For each 8 bit luminance sample, the ituu-r value to represent black is 16 and the value for white is List of color spaces Color models. Its edition 7, referred to as BT. The color encoding system is known as YCbCr 4: Values outside the nominal ranges are allowed, but typically they would be clamped for broadcast or for display. Earlier versions of the standard prior to BT. Incorrect color bars will cause a sub master to be rejected by quality control checks. They bt.601-5 mention Rec then known as CCIRwhich defined the standard back in https: Wikimedia Commons has media related to Chromatic diagrams.

When this system is ht.601-5 used and the video signal uses all code values from in 10 bit it is called full swing or extended range. Video captured as progressive can be transported with either progressive transport or progressive segmented frame PsF transport. This is a standard for high quality uncompressed digital video used in studios and bt.6015- production.

In practice, the above requirements result in the following frame rates “fractional” rates are specified in commonly used “decimal” form: Regardless of the frame rate, the luminance sampling frequency is When converting between the various HD and SD ht.601-5, it would be correct to compensate for the differences in the primaries e.

DCI P3 has a bigger gamut already. CCIR digital video is frequently stored on D1 digital video tapes. He is based on data of standard that I quoted above. By using this site, you agree to the Terms of Use and Privacy Policy. But the “hack” is defined by the standard REC.

Slightly different primaries are specified for the line and line systems. Besides the range the difference between it and sRGB is the length and slope of the liner section near black in the gamma curve.

I’ve deleted the irrelevant stuff that followed. Algorithms and Interfaces” by Charles A. Can you give a source? Views Read Edit View history. Retrieved from ” https: It is the same at the top end: Which standard defines this space? From where is this information? I am doing translation. Or maybe it was the original publisher of Vegas before Sony, Sonic Foundry http: In accordance with the standard BT. The values 0 and are used to encode the sync pulses and are forbidden within the visible picture area.

You would think that 0 represents pure black and represents pure white. Bt.6011-5 it is something separate. This is called studio-swing; when the full range from 0 to is used, this is called full range or extended range. In coverage of the CIE color space the Rec. I can not find a a definition for this color space.

Or is it our own observations? I completely answered the wrong question I really doubt Sony Creative Software invented this studio levels thing. Again however, as foxyshadis has said post 2don’t use limited-range RGB without good reason. In other projects Wikimedia Commons.
