HDCP-How to?

[venkatsiddaredd]

Hi,
I know that there was a lot of discussion on HDCP on these forums.
I checked these posts http://www.sevenforums.com/graphic-cards/40261-what-hdcp.html
http://www.sevenforums.com/music-pi...nding-hdcp-blu-ray-copy-protection-its-h.html
I still have few doubts. I will extremely thankful if some one can help me clear my doubts.

I am building cinema player for an art house film club here in India. We have a small chain of places where we can exhibit our films. We also screen some commercial films here on some weekends.

My graphics card is HDCP enabled.
Now all I want to do is to protect my content using HDCP. I know that HD-DVD and Blueray are protected by the way of HDCP. But my content is HD video in avi/h264/mpeg4 format. Now if I want to play my content safely (preventing DVI/HDMI splitters) I need to utilise the HDCP capability of my graphics card. But how do I notify my graphics card that my content should be played using HDCP encryption. Like Blueray players has a protection mechanism I would like to implement the same in to my video/audio files or in to the media player so that when these files are being played back I would like HDCP enabled.

Thanks
Venkat

Of what I can understand is that you want to show your stuff with HDCP protection enabled. As far as I know, there is NO way to protect your content from home. Also, HDCP uses a "key" to encode the content... However, if no software knows the key (it's heavily encrypted), they won't be able to playback anything. That is why most blu-ray players on the market are regularly updated with the latest blu-ray releases or at least connect to a database to be able to get the key. HDCP is only for Blu-ray Video discs. You can't protect a file on the hard drive with HDCP. If you want to do that, encrypt the hard drive (not safe imo).

If you are going to play commercial movies, all you need a HDCP compatible graphic card, HDMI and HDCP enabled monitor.

I will be playing commecrial movies too.
We would be encoding the video using our custom codec. Once encoded the files are encrypted and loaded in to the media server. The operator then can playback the video.
Since the files are encrypted and decypted on the fly during playback we do not have probelms with the security of the files themeselves.
But we also want to protect the link between projector and server so that no pirate can steal the video using DVI and HDMI splitters>
In this scenario what is the best way to implement the security of the video signal.

I'm not an expert, but when setting up a home system and trying to get my head around this stuff

Windows 7 has strict HDCP protection built into the OpSys to full anti-copy standards (unlike XP etc)

Therefore it will auto-detect a blu-ray and ensure the leads/adaptors/pci-e cards/output monitor/projector all adhere to the standard for High Definition playback.

If any item of the detected 'chain' fails the HDCP 'test' (ie not compatible) video/audio playback is reduced to dvd quality or simply won't show anything.

Hi,
thanks for the info.
But what if I want to play a HD quality video encoded by me. I hope windows cannot identify that as an HDCP encoded movie.
If I want the same thing to apply (as windows applies the security to Blueray) for my HD movies too, what is that I have to do?

Please advice
