|
|
Hi,
Any recommendations for a good capture card to capture 1080p signal from the HDFury on a PC ?
I have no idea which would be best and which HDFury to buy for it.
Any suggestions welcome

Welcome to the forum. There are much better ways of capturing HD then in the analog domain. What types of signals do you want to timeshift?

The input is an HDMI signal (sometimes with HDCP, depends on which channel I'm watching).

Capturing uncompressed HD via HDMI is really not practical at this time. I have heard it takes about 1tb of storage for about an hour worth of programming. I assume your trying to timeshift direct broadcast satellite or HD cable. I don't know of a realistic solution for those types of signals. Perhaps someone else will chime in.

I have a digital HD cable and they provided a HD recorder, but it's awful to use... fast forward or rewind is extremely unstable, sometimes the whole thing just crashes and resets itself, which means you have to wait 15-20 minutes to have it sync again, etc.
My idea was to record using the HD recorder and then to transfer recordings that I want to be able to fast forward (like the Olympics) on the PC.
Isn't there a card that supports real-time compression ? Given the fact that the HD recorder can store it on disk, I suppose a PC must be able to do the same thing, or am I far off now ?

If we are talking about over the air HD or clear QAM Cable (Non Premium) Home Run HD seems like a cool solution.
http://www.newegg.com/Product/Product.aspx?Item=N82E16815327005
It has 2 tuners and streams HD over ethernet. It will work with Windows, Mac or Linux. I want to pick one of these up to play with when I get a chance. Decent price too @$170.00.

The signal I get is through HDMI only. So I thought I'd convert it using the HDFury2 and then use a capture card, but that doesn't seem an option then ?

If your cable system provides clear QAM, by law for locals they are required to. The HomeRun HD replaces your cable box.

I should clarify it's in fact not cable, it's digital TV over VDSL, so I can't hook up anything else than the decoder from the digital TV provider.

HD DVR's aren't compressing anything, though. They're just capturing an already highly compressed stream (3-4 megs/second) and storing it on the disk.
There is the Hauppage HD PVR that will capture and compress HD in real time to AVCHD, but your quality will probably be significantly less than the original signal. Maybe not bad, but probably not great, either. First, you're starting with a compressed signal, then you're at the mercy of how good the component outputs are on your source (D/A), then you're digitizing (A/D) and compressing that signal (again). Not ideal of course, but maybe it would OK.

You can also use an HDCP stripper and capture the signal fully digital with something like a BlackMagic card, but it's definitely not user-friendly as a home/CE device and it would take mountains of disk space. Definitely not a solution for time shifting episodes of Weeds.
There's really no good way to do what you want to do.

I don't get this. The signal I get is indeed compressed (takes up 11-12Mbit/sec on the VDSL according to the technician) and then gets decompressed and output on HDMI. Since they compress it on the other end, can't I do the same to the HDMI signal ? If devices such as the Hauppage HD DVR can do it, there must be PC capture cards that can do it too ?
Sorry, I'm pretty new to all of this...

I'm located in Belgium. The product I have is Belgacom TV, which is offered on a VDSL2 connection, using FTTC (I'm connected to a node about 200m/600ft from here).
I'm not sure what brand of decoder/recorder I have, because they put their own label on it. But it has HDMI and SCART outputs.
There's also a digital TV cable provider here, but I'm not sure what standard they follow. I wouldn't be surprised if it was a closed system too... typical for Belgium !

I've got the HD PVR. Haven't spent a lot of time playing with it, but it seems real nice. I haven't been able to figure out how to get full screen yet(to show how much I've played with it).
Blackmagic really isn't all that great for the price. Does something like 8 bit 4:2:2 uncompressed mpeg2 encoding. The nice thing with the Hauppauge HD PVR is hardware h.264 encoding, and it is $100 bucks less. As long as the source is the same quality, you can probably get the same PQ with the HD-PVR with a lot less space.
I'm not going to say run out and buy it yet, but it seems to do the job and be fairly stable. If I develop a firm opinion any time soon, I'll post it.

The Hauppauge HD PVR seems ok at first glance. Acording to the specs you can do 2 hours at 5mbps so a one hour show per single layer DVD at 10MBPS wouldn't be that bad would it?
You would have to set your digital box to output 1080i though as it doens't capture 1080p
