A question about the Pal XL2 CCD
The specs for the pal Xl2 say that in wide screen it uses 960 pixel horizontally, the NTSC model does too. So, there is no more pixels horizantally in the pal than in NTSC. However the Pal chip has 800,000 pixels per CCD while NTSC has 690,000. There has to be more pixels vertically (not that the pal needs anymore than the NTSC) in the Pal version. I already now the NTSC chip is 960x720, so what's the pal version's? All i can think of is that it is 960x850

Pal has 576 and NTSC 480 vertical Pixel.

I know that. I'm talking about the entire CCD Block not the video standard

If the PAL one has 800,000 pixels and it's still 960 wide then height must be 833.

We know for sure that the NTSC chips have a certain area above
and below the "content" area that are not being read (to get a 16:9 CCD). I assume on PAL the content area is simply increased and the not used areas are decreased. That sounds like a simple and perfect workable plan to me. I don't think they would put different chips in there. Makes sense?

Hi Rob,
nice idee but this can not work. If "the content area is simply increased" its no longer 16:9 ratio. So it must be another chip used. regards Daniel |

If the total pixels count isn't the same, it can't be the same chip.

Jean-Philippe: I'm pretty sure they are talking about effective
pixel counts, not the maximum number of pixels on the CCD's. Daniel: yes it will due to pixel aspect ratio's. Ofcourse it will probably have a wider resolution as well to get the different PA in the first place. Then again it could be different chips as well. There also concerns for DoF and FoV, ofcourse.

I mean. If it is the same chip - it must be also the same pixel size. And so the content area can not in both case 16:9
