HIS iClear = Clearer audio/video?

Zorlac · 03-10-2008, 06:50 PM

I saw a picture of this from Cebit and found the product on the HIS site:

http://www.hisdigital.com/html/product_ov.php?id=340

"HIS iFilter card provides a better image with clear picture
HIS iClear card provides better gaming experiences by reduce the distortion and noise generate from graphic card.
It can eliminate the noise generate from high-end card such as 8800GTX, GTS graphic card to provide a "clear picture" when they play can
HIS iClear card provides an ultimate HD experience by reduces the distortion and noise generate from TV tuner card."

Snake oil?

All I see are some caps, and resistors.

Wiggy McShades · 03-10-2008, 06:53 PM

i dont get it if you look at the card its just a pcb with a few capacitors on it.

NickS · 03-10-2008, 06:54 PM

How the heck does it work?

Sometimes, that's all it takes to clean up a signal. I'm not aware of any video noise that needs cleaned up from a gfx card though.

well yeah but how would a separate card clean the video signal from my graphics card?

Good question.

Guys what you don't see is the magic inside. :-P

I honestly don't know. I see how only a few components can clean things up, but I don't get how this separate card can clear things up

ohh i see it now the card runs on hopes and dreams.

Goes great with your KillerNIC and physx card

ryboto · 03-10-2008, 07:12 PM

my HD 3870 makes some signal noise under 3d, it's clearly audible over the rest of the system. Then again, the fastest spinning fan in my system is quieter than my loudest hard drive, so my system may be atypical.

Same thing I was asking myself

MuffinFlavored · 03-10-2008, 07:16 PM

Reflective PCB?

ChaosMinionX · 03-10-2008, 07:23 PM

might be some sort of EMI/RFI shielding that you put inbetween your videocard and soundcards... since most Mobos have PCIE1x inbetween the PCIE and PCI...just a guess though.

I was going with that guess, but not a lot of motherboard makers have the open slot.

ZOMGVTEK · 03-10-2008, 07:31 PM

Without a doubt, it would help clean the power going to your video card. But the difference would be so marginal by any measure, its not a big deal. It looks like they are using larger electrolytic caps to store enough to help minimize transient fluctuations, and some smaller SMT style caps. Im not sure what frequencies a video card can throw back into your power, but those smt caps look a bit large to do much good.

If its under $20 and you are experiencing problems likely associated to your video card, such as you 'hearing' your video card through your headphones, then it might help. But getting a bigger and better PSU that has larger internal capacitors and is designed to put out more power would likely do more. But that aint cheap...

And yes, its likely that the main surface of the board is unetched copper clad, and would help to shield your sound card from other devices with proper use.

All of these custom built computers throw rf all over the place, and all the devices have to do massive corrections to adjust for that. Might account for the differences when you run a benchmark twice in a row and you get slightly different results... That should not happen assuming constant conditions.

That makes a bit more sense. I was trying to figure out how it would clean up video.

WeStSiDePLaYa · 03-10-2008, 07:37 PM

this is about 2 dollars of chemicon P series polymer capacitors, and 20cents worth of ceramic capacitors.

No resistors.

All this does is add extra capacitance to the power rails available through the pcie slot.

The reason all the silk screened cap spots aren't filled, is because it was probably too high of capacitors, causing too large of in rush current and causing boot issues.

I have dealt with power conditioners, and every bit of capacitance i added to the line increased the resolution i could get out of the tv. Not noticeable to most, but the difference is there. The right size and type capacitors can seriously clean up signals.

The moral of the story is, this card isnt going to do anything... That you notice.

Monkeywoman · 03-10-2008, 07:38 PM

i bet they are going to sell it for 150 bucks.

ToTTenTranz · 03-10-2008, 07:39 PM

A bunch of capacitors between the PCI-E power and ground supplies? It should decrease the power supply's noise for the PCI cards.. but I guess most motherboards already take care of that.. And why did they make such a big card to store 7 small capacitors?!
I wonder if this will ever make any difference at all. And audible at that.

Nothing like a RightMark AA -based review to prove it.. In case some reviewer ever bothers..

I would say this would have the biggest impact on something sensitive, like a analog tv tuner... Otherwise, i couldnt see it making a difference.

Pretty much garbage.

Well yes, no reason to get it... Unless youre REALLY into getting channel 2 off the air as perfect as possible and dont want to modify anything.

I see youre into your headphones...
