What I'm after is a way to display from an HDMI source the output on my iMac, at the moment I use eyeTV via a scart convertor to display tv from a non-high def cable box. I want basically to upgrade the box to a high def one and just use the iMac as a monitor... ideas?

I don't see anything with HDMI to coax but you're going to loose quality.

I'd wait and see what comes out at CES this year.

why don't you get a vid in for the mac and just plug the coax right in?

Re: Capture card with DVI/HDMI input

--------------------------------------------------------------------------------

A raw HDTV stream is roughly 1.5Gbps. The hardware required to handle this level of information and encode it on the fly simply is out of the consumer's budget at the moment. In the professional video market there are devices that will do this, in the $2000-$10000 range.

When the hardware becomes cheaper, it may show up, but then again, when it is cheap enough the demand may not be there. With the push for HDCP being required for next gen settop boxes it would mean that there simply won't be unprotected DVI/HDMI signals to capture, and if the device is HDCP compliant, then it will have to respect the copy restrictions put in place on the content.


but I think it's mainly a copy protection thing. there are no tv tuners or capture cards with component, dvi, or hdmi due to hdcp. I have seen one or two cards with component inputs but the limit is 720, my aiw component out only does 720p which is why I don't use it.

but what have we here?
black magic

unfortunately it's only for editing and is not hdcp compliant.
Quote:
The HDMI standard sometimes includes copy protection encryption, such as commonly found on DVD players and some brands of set top boxes. When connected to these copy protected sources, the HDMI specification defines that Intensity cards cannot capture. Always confirm copyright ownership before capture or distribution of content. Intensity media file formats are fully compatible with DeckLink and Multibridge capture cards. Compatible with Microsoft Windows™ and Apple Intel based Mac Pro systems. Apple Power PC systems are not yet supported.

Blackmagic uses an Xilinx FPGA. Ya'd just have to hack it..... with a $5000 dev kit.

Been doing research on ATSC and QAM modulation.

ZeeVee has a consumer ready QAM modulator.
Upside: Its cheaper than pro gear
Downside: Its still $1000

Supports up to 720p

http://www.zeevee.com/connected-home/zvbox150

Pro gear starts around $3000+, but you get the delight of 1080p realtime encoding.
