[New-bugs-announce] [issue45775] Implementation of colorsys.rgb_to_yuv and vice versa

[Thomas Stolarski]

New submission from Thomas Stolarski <thomas.stolarski at gmail.com>:

Since the implementation of `rgb_to_yiq` roughly 30 years ago now, the advent of HDTV has resulted in most broadcasting and video processing having moved towards Rec 709 (or BT.709).

While I know colorsys has been on the chopping block for a while, it seemed a little silly that what is now arguably the most common color space used in video editors isn't available as part of this module, despite being a matrix mapping like much of the others.

YUV is a bit more contentious on its definition than YIQ is, but it is still widely used to refer to Rec 709 and this is the ATSC standardization for HDTV.

I've written a PR for both conversions and will add it to this ticket once it's up.
