Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

HDMI --> PCI Interface?


Is there such an aminal? Is there such a driver for it?

I want to capture video out from my Dishplayer 942. It's getting eingefullen.

NO. Even if there is one. It will not be in anybody's price range. Also it will be 100% in-compatible with Linux.

Why? A digital-to-digital bridge would be very straight-forward, hardware-wise.

But I now find that encryption (HDCP) is on all the time, specifically to prevent such actions as I want to take?

Maybe I have to resort to component. Any suggestions for component video HDTV capture?

Or why not D-DVI? Same signaling as HDMI. Newer cards should have HDCP in it.

Find an YPbPr (component) to S-Video encoder that connects to the component video.

For DVI, find a connector that converts it to VGA and then use a RGB to S-Video encoder.

I doubt that the card at http://www.digitalconnection.com/Pro...deo/mdp130.asp will work in Linux. A $200 is a high price to pay for a card that has no chance of working in Linux.

You need to understand that companies write software for Windows. Because of this the Linux community have to reverse engineer the code for the card above or any HDTV card to work.

You can get the AVerMedia AVerTVHD MCE A180 or KWORLD ATSC-110 to capture high quality video from S-Video. I think these cards uses Philips SAA7135 chip. I suggset getting the Kworld card because it looks like it has audio output to feed it to the sound card. The SAA713x module in Linux does not have good support for audio capture, so you have to use a sound card. I suggest Audiotrak Prodigy 7.1LT for good sound recordings.

Thanks, but I'd rather not record, than record SVideo.

If have a source device which puts out DVI-D, what is the nature of that signal? Is it LVDS, encoding digital data? If so, how is the speed rated, with symbols, or bits, or what? What modulation? What else should be known about the signal?

Assuming my DVI-D is not HDCP, what does this mean if I want to record HD video? If the data rate is too high to record, why hasn't Firewire-800 had the same problem?

OK, here's one that will record SD, HD, 2K & Dual Link HD, and has Linux drivers from here. Anyone have any experience with this?

Or know what capture card this gear is using?

The price tag is way too high for anybody unless you have won the lottery or getting paid as much as Bill Gates. The equipment is for studios that invest in billions of dollars for a movie. It is ok to dream but you have to gauge your obession of quality versus your bank account.

You need to ask your self is your satellite TV provider sending you true HDTV or psuedo "fake" HDTV content? If it is fake, there is no point buying high quality video capture equipment. Probably 99% of the content on your unit is fake HDTV. The other 1% is HDTV. If you buy a DV recorder and hook up to your computer through IEEE-1394, it will still provide you the best quality and it will be in your price range. If your unit recorded in a lossy compression like MPEG, again there is no point to get very, very, very expensive equipment.

On my shows, I can get by using a 422p YUV color space which provides 16 bit color (actually its 15 bit color) at a resolution of 360x480. The amount that ffmpeg HuffYUV will take up is about 20 GB per hour and this is with out sound. If I want to include sound using PCM as the codec in the recording, I need at least two (2) hard drives in RAID-0 (stripping) to handle the throughput during writting. My sound card (Audiotrak Prodigy 7.1) can record at a sampling rate of 96 KHz at 24-bit stereo, but that will waste too much space. CD quality sound is all I need. Of course I will be using XFS as my filesystem.

I see. If I'm understanding, what you suggest is buying a video camera and recording the image from my screen?

The Kona card is $975, not as bad as you'd think.

I am gathering now, that my Dish 942 DVR puts out HDMI without HDCP. I had understood that HDMI always is HDCP, but a credible source on AVSForum says not for this DVR. This eliminates the need for an HDCP stripper.

However, with the Kona card, I'd need to convert DVI to SDI, and I don't really trust that, plus I don't have the PCI-X needed. I could upgrade, but I'm starting to think that just recording component HD would be a better solution for now. Of course the interface card would need to compress in hardware, to relieve the disk. I don't care what compression format, as I could transcode to DiVX off-line.

So I guess that's the direction I'm reluctantly forking now.
