HDMI Splitter

Is this a legit hdmi splitter? Seems kind of cheap to be a powered splitter that can do 1080p:

I know theoretically they should be cheap since all you need is 2 high speed opamps, but I am still skeptical.

Looking to buy asap so any input would be appreciated.

Sorry, also need your opinion on this:

http://cgi.ebay.com/HDMI-Component-V...item563c1de354

HDMI to component converted. It says it supports HDCP, does that mean it strips it since component does not have HDCP? I'm looking to use this on my PS3 for a blackmagic intensity pro, want to make sure this works as far as HDCP is concerned.

I suspect that it means that it will not convert it if the incoming content requires HDCP. Or it may mean that it will not convert it to a high resolution if HDCP is required and the Image Control Token is present.

I have no problem with image control, but why would it support HDCP if it's not converting, wouldn't that mean it DOESNT support HDCP?

Also, any info on the splitters?

If receiving HD resolutioncontent over HDMI that requires HDCP you are not allowed to convert it to HD resolution Component if the Image Control token your are required to convert to SD component. And yes this is because component does not support HDCP and therfore the component content can be copied.

So what exactly does that mean? If the device SUPPORTS HDCP as the device indicated, that the device will convert the content to 480i?

that's cute. There are up to 6 high speed TMDS lines, none of which are terminated with an op-amp. Not to mention the handshaking that must occur.

You have it backwords if it supports the HDCP rules that means it will NOT convert content that has the ICT (image constraint token) set to HD resolution component see:

As far as the splitter goes, I would personally buy one from monoprice or like website. Shipping on that particular one from ebay is $15...more than the price of the splitter. Plus, it is coming from Hong Kong...last time I purchased something from a seller from Hong Kong was my Broadcom Crystal HD card...back in January and have never received it.

Stick with the well known sites before hitting up ebay. You always get what you pay for.

Sorry, I'm used to analog video buffering (which is done with high speed opamps), haven't worked with HDMI. Besides, when I said opamp, I really meant it as a general term for a buffer. I know HDMI signals were some form of LVDS but I assumed the signals were buffered with fully differential opamps of some kind.

I see, so does that mean it won't convert PS3's hdmi to component?

No in fact there is no evidence to indicate the any studio will set the Image Constraint Token until 2012 at the earliest and it at that time the ICT is set on some HDMI content then it will still convert it to SD component.
