DVD 10bit, 12bit 28bit ?????

[NewAudioBuff]

Hi,
Recently one of my friends was going nuts in FRYS trying to search for a higher bit (10, 12 or something like that) DVD player. I don't seem to understand this. Is it really possible to see the difference in picture between a 10-bit and a 28 bit dvd player? Also, I use a samsung HD931 DVD player which converts the 480 signal to 1080 for my hd tv. Does these bits play a significant role in my dvd player?

No, it is not possible from what I know. 10 bit is more than enough. But then you know how powerful marketing is, don't you?

Well this isn't exactly a marketing ploy this time. What the higher bit chips and sampling rate bring to the table is the ability to better resolve shadow and fine detail within the picture. Some 10 bit chips have a tough time with this low level information.

How many levels are needed and what bit rate would that be? What can the eye detect? I was told by in th eknow that 10 bit was enough. That is 1024 levels of scale.

Your question is unclear and inconcise. However you can sit closer to digital televisions and therefore the eye can detect more detail than it could with analog television. If the DVD player is non progressive, then 10 bits would be enough. But with DVD players that feature progressive scanning, 12 bit chips actually do a better job of of fleshing out more low level detail(remember you are sitting closer to the T.V) and therefore give the eye more to see. Whether the eye can see that low level detail is different from one person to the next, the size of the screen, and what type of display device you use. The higher the bitrate and sampling rate, the better the picture is. There is a point of diminishing returns, but 12 bit DAC's are not quite at that point.

I got this information from Joe Kane at his last Imaging Science workshop so don't kill the messenger.

Now why would I kill the messenger? I would just interrogate them more
Now we have 12 bits or close to it. Some suggested that 32 or 64 may not be enough.
