Question:
does having a 12 bit video decode mean that you get a better picture, it seems most have 10 but some like phillips and a ronin player have 12?
DVD as a format is only 8 bit, but higher players up-convert the signal. You don't get any "improvement" as such, but you get less obvious blocking etc.

You don't get any "improvement" as such, but you get less obvious blocking etc. Yeah, although DVDs are only 8bit(per colour channel), by perforiming the decoding etc. in 10 or 12 bit per channel colour space helps avoid rounding errors accumulating, and as Adamant mentions, this has most effect in avoiding any blocking in large colour fields.
A good example would be to take a high res bitmap image, reduce it to 8 bit colour and see what that looks like. Then (if your image editing programme allows), take the same image and reduce it to 10 or 12 bit color. That will give a (quite rough) approximation of what the difference will be.
Hmmm...I don't buy that. In your example you're reducing the colour depth of an RGB image from 24 bits to 8 bits, so yes, it's going to look mighty rubbish in 256 colours (or 1024 or 4096 colours).
I think the "10-bit DAC" on DVD players affects the YUV conversion to RGB or something to give effectively a 30-bit RGB image. Damned if I can notice it on my player though - I still see banding.
I'm probably completely wrong though :help:
I'm not totally sure.
Try what i said on a YUV encoded image then. ;)
It must be a good feature to have, whatever it does.
My Samsung claims quite proudly to have a 10-bit video DAC. Oooo....and don't forget the 24-bit 96KHz audio. Like that's ever going to be used!
