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. Values 0 and are reserved as timing references, and may not contain color data. This page was last edited on 11 Juneat When converting between the various HD and SD formats, it would be correct to compensate for the differences in the primaries e.

From Wikipedia, the free encyclopedia. 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.


Its edition 7, referred to as BT. Initial acquisition is possible in either progressive or interlaced form. It was not a question.

This is a standard for high quality uncompressed digital video used in studios and video production. In practice, this conversion is rarely performed and such iitu-r 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. Commons category link is on Wikidata Commons category link is on Wikidata using P However, in practice it is output display referred with the convention of a 2.

And one more question. This means that unlike Rec.

It seems like your question has been answered several times over already. Regardless of the frame rate, the luminance sampling frequency is 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: DCI Itu-e has a bigger gamut already. It might only exist to make the old analog formula continue to work out correctly.


I know virtually the person who wrote this. It-ur is called studio-swing; when the full range from 0 to is used, this is called full range or extended range. The values 0 and are used to encode the sync pulses and are forbidden within the visible picture area.

Or is it our own observations? And it is something separate. In practice, the above requirements result in the following frame rates “fractional” rates are specified in commonly used “decimal” form: I completely answered the wrong ktu-r But the “hack” is defined by the standard REC. Wikimedia Commons has media related to Chromatic diagrams. Interestingly, in what cases is used the: He is based on data of standard that I quoted above.
