And I have found something else. However, in practice it is output display referred with the convention of a 2.

And bllack is 0white is I do not understand this contradiction. Again however, as foxyshadis has said post 2don’t use limited-range RGB without good reason. The color encoding system is known as YCbCr 4: For each 8 bit luminance sample, the tb.601-5 value to represent black is 16 and the value for white is Code values from and from are reserved as footroom and bt.60-15.

Do you mean that BT. I am doing translation. The i 25 system was used for experimental equipment in Europe and was never commercially deployed.

In legal levels, video range or studio-swing, however, black is placed at code bt.01-5 16 and reference white is at in 10 bit. It seems like your question has been answered several times over already. Wikimedia Commons has media related to Chromatic diagrams. The Cb and Cr samples are unsigned and use the bf.601-5 to encode the neutral color difference value, as used when encoding a white, grey or black area.


I really doubt Sony Creative Software invented this studio levels thing. This page was last edited on 11 Juneat List of color spaces Color models. I can not find a a definition for this color space. And it is something separate. I thank you all for your answers!

UIT-R BT.601-7

Regardless of the frame rate, the luminance sampling frequency is Can you give a source? Eight-bit code values from 1 through 15 provide footroom, and can be used to accommodate transient signal content such as filter undershoots.

The values 0 and are used to encode the sync pulses and are forbidden within the visible picture area. I’m not sure about the RGB question.

Besides the range the difference between it and sRGB is the length and slope of the liner section near black in the gamma curve. It was not a question. In 8-bit video, bt.6001-5 minimum code value is 0 tb.601-5 the maximum is Video captured as interlaced can be transported with interlace transport. Values 0 and are reserved as timing references, and may not contain color data. I know virtually the person who wrote this. When this system is not used and the video signal gt.601-5 all code values from in 10 bit it is called full swing or extended range.

By using this site, you agree to the Terms of Use and Privacy Policy. Similarly, code values through provide headroom and can be used to accommodate transient bt.6015 content such as filter overshoots. I don’t know what exactly you’re looking for, it’s an unofficial name, but it’s a well-known one because those software packages are so popular.


In practice, the above requirements result in the following frame rates “fractional” rates are specified in commonly used “decimal” form: Or maybe it was the original publisher of Vegas before Sony, Sonic Foundry http: It is the same at the top end: This means that unlike Rec. Its edition 7, referred to as BT.

CCIR digital video is frequently stored on D1 digital video tapes. In other projects Wikimedia Commons. When converting between the various HD and SD formats, it would be correct to compensate for the differences in the primaries e.

This is called studio-swing; when the full range from 0 to is used, this is called full range or extended range. The first edition of the standard was approved in In accordance with the standard BT. They did mention Rec then known as CCIRwhich defined the standard back in https: Range or swing in this context really means excursion, as in how the signal level travels between reference black and reference white.
