However, in practice it is output display referred with the convention of a 2.

Rec. – Wikipedia

The color encoding system is known as YCbCr 4: Do I understand correctly? 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. Similarly, code values through provide headroom and can be used to accommodate transient signal content such as filter overshoots.

And bllack is 0white is I do not understand this contradiction.

Regardless of the frame rate, the luminance sampling frequency is 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.

The standard has been revised several times in its history. And one more question. HDTV according to Rec.

BTW the standard allowed for bit quantization right from the very beginning, so saying “” is a simplification, but we all know what is meant. I know that REC. 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. This is called studio-swing; when the full range from 0 to is used, this is called full range or extended range.

Interestingly, in what cases is used the: Video captured as progressive can be transported with either progressive transport or progressive segmented frame PsF transport. It might only exist to make the old analog formula continue to work out correctly.

I am doing translation. Retrieved from ” https: In legal levels, video range or studio-swing, however, black is placed at code value 16 and reference white is at in 10 bit.

In 8-bit video, the minimum code value is 0 and the maximum is It seems like your question has been answered several times over already. But the “hack” is defined by the standard REC. Or maybe it was the original publisher of Vegas before Sony, Sonic Foundry http: Initial acquisition is possible in either progressive or interlaced form.

I really doubt Sony Creative Software invented this studio levels thing.

This page was last edited on 11 Juneat He is itu-t on data of standard that I quoted above. The values 0 and are used to encode the sync pulses and are forbidden within the visible picture area. CCIR digital video is frequently stored on D1 digital video tapes. And it is something separate. Slightly different primaries are specified for the line and line systems.

You would think that 0 represents pure black and represents pure white. Bbt.601-5 and Interfaces” by Charles A.
