rhysb:

Some of the newer Nvidia & ATI cards provide HDCP over DVI, so you don't necessarily need to have an HDMI output.



Yes this is true. Plus some TVs and monitors support HDCP over DVI.

The point I'm trying to make is to watch freeview in HD from a PC based tuner you don't require HDCP.

No1Daemon: So updated drivers will do the trick? I am installing a Hauppauge HVR3000 currently and only chose it because it was a hybrid DVB-S/Analogue and also DVB-T and I didn't really want to change cards next year just to use the DVB-T service instead of satellite.



I don't think the card or driver really anything to do with it. the DVB-X card is more like a network card receiving data, it's the PVR Software and codec that processes that data whether it be MPEG2 or MPEG4 or whatever. Someone please correct me if I'm wrong.

So your saying that even if Freeview set HDCP "on" then it is possible to get a PC based tuner to still receive the HD broadcast but drop the HDCP encoding?

I realise that HD can be played without HDCP and have done so, just trying to nail the requirements down as if Freeview do use HDCP on some HD material and as the PC I am planning on using as a media center does not have any HDCP built in if I can't drop the HDCP then I have a problem with my intended hardware.

My understanding is that Vista is the only operating system that currently has an encrypted path to allow the output of protected content, that's why MS require signed drivers etc. Which means that if Freeview were to turn on the broadcast flag you would only be able to view it in HD on Vista with an HDCP compliant video card and display. However you should still be able to view it in SD on other platforms.

I believe apple is also looking to add the DRM stuff required to OSX, not sure of the timeframe though.

If they do turn on the broadcast flag, will this make us the first country in the world to do so?

Hi McraeNZ. I read your howto on your system and it gave me a lot of ideas.
I was the one who questioned you on where you had got your sat card with ci.
Good to see you on here.

Ok you are still missing the point.

On broadcast there is no HDCP. There is a flag that tells the STB  to turn the HDCP between it and the screen on or off.

If you have a PC you just ignore the flag and watch the unencrypted HD content.

And in what manner do you get your pc to "ignore the flag"? Is it hardware or software based?

I believe the only time HDCP is ever an issue on a PC is if you are using it to watch a BluRay/HD-DVD. And, as said before, you will still be able to watch it in SD if you do not have HDCP compliant GPU and monitor/TV.

So watching anything other than a blueray  or hd dvd is not a problem. Then that still leaves me with my original question for future proofing your media centre which is how do you get your pc to ignore the hdcp flag so you can play hd dvd and bluray

The only way to strip it on a PC is to use AnyDVD which can remove the DRM stuff from some BlueRay & HDDVD disks. Otherwise you need a setup that has DRM all the way ie Vista/Signed Drivers/HDCP.

OK sounds good. Now I just need to see if I can coax my aging P4 2.8 HT to handle HD broadcasts.. oh and convince someone to upgrade the local TV tower...

The motherboard I have chosen has a daughter board with HDMI that it compliant with hdcp so I shouldn't have to worry hopefully.
Otherwise ANYDVD is easy enough to get hold of.

Thanks

What board did you go for? I would suggest steering clear of an Asus M2A-HDMI. I got one of these a few months ago when I rebuilt my PVR and regret it as they are full of problems.

Thats unfortunate because I got the ASUS M2A-VM HDMI. What sort of problems did you encounter with it?
