More HVX200 info

[Harlan]

The “14-bit DSP that’s internally 19-bit” is actually a 19-bit A/D convertor feeding the 14-bit DSP. In otherwords the data path from the CCD’s to the DSP chip is 19-bit, once it hits the DSP it becomes 14-bit where all the signal processing is applied.

I believe. It’s hard to decipher the translation.

I saw that website too. One thing I noticed about the specs is the lack of a 1/48 shutter speed (180 degress) and a 1080p recording option. Hope we don

Hi Rodrigo,

Those two shutter speeds are within the synchro scan speeds, just as they are in the DVX100 series.

Best,

Thanks for the info. Although the way I read it, with it’s “wide pixels” is something like 1280×720 with pixelshift in the DSP to 1280×1080, and then downconvert to 1080i, 720p etc. Perhaps. I don’t know.

The interpretation done by Babelfish is interesting. It is a 1080P/60 capture and it is down converted from there. The chip is an analog device and should always be regarded as such.

Best,

Maybe I’m missing something here, but if the CCDs are 1080/60p native, then why can’t we record 1080/60p to the P2 cards?

While on this topic, what is the image size and pixel aspect ratio of a 720p recording and 1080i (and 1080p) recording on P2 cards?

Brian,

[Brian SaenzDeViteri] “if the CCDs are 1080/60p native, then why can’t we record 1080/60p to the P2 cards?”

I’d guess that there’s no codec for it, …yet. DVCPro100 just doesn’t have the space for that many pixels at that temporal density. It’d have to be closer to 200 Mbps to do that with quality. Of course, now we can see another good reason why the P2 cards are raided memory chips. They’ve got the speed to handle DVCPro200 if there were such a thing, and I’d bet there will be or something similar eventually.

especially this tidbit: “In all image chestnut thornback tar…”

Those are secret instructions to Panasonic agents around the world.

[Barry Green] “…apparently the CCDs are natively scanned at 1080/60p.”

I’d like to know the horizontal resolution of the chips and is it same with European models?

So, maybe there’s no pixel shifting at all?
I’d thought it would have been better way to use 720p chips and vertical pixel shifting for component recording formats. That way the chips would have been a lot more sensitive.

[toke lahti] “So, maybe there’s no pixel shifting at all?”

Except that Jan has repeatedly said that the HVX’s CCDs will use pixel shift. In one DVXuser post, she said, “All pixel shift does is cover the non-photosensitive areas, the registers, and give more resolution.” And in another, “Without pixel shift/spatial offset, you would have vertical stripes in the pictures, which once the light became low you would see.” From this I gather she means that pixels are shifted or staggered so that there would be no visible gaps between them. Beyond this, it hasn’t been revealed how much the pixels are shifted.
