UYVY in Max, what standard is used to display/convert to RGB?

What formulas or standards does Max use for any needed UYVY -> RGB conversions in objects like jit.window, jit.pwindow, jit.gl.videoplane, etc.?

I ask this because in today’s world of HD (720p or higher) resolutions, often the encoding is actually not UYVY (or YUY2) and is instead YCbCr using the BT.709 standard. The latter is the HDTV standard for anything HD (720p+). This newer standard has material changes in formulae from UYVY (old school YUV or BT.601).

I understand that I can always write my own shader and convert the data myself. I also understand that the shaders distributed w/ Max in the Cycling ’74\jitter-shaders\color folder are based on the non-HD standard of BT.601 with studio-swing.
