    By far missingremote helped me a lot in understanding HDCP clearly.

    I was under assumption that we have to encode/encrypt the videos with HDCP.

    But this article http://www.missingremote.com/blog/high-definition-optical-discs-and-their-associated-copy-protection-acronyms cleared my doubts.

    So the content it self need not be encrypted with HDCP. Am I right?

    My video files are encrypted using AES encryption alogorithm and is decrypted on the fly.

    Now I have a graphics card from Nvidia which is HDCP ready. I checked the HDCP status and it says HDCP is enabled. Now if I connect my server (with Nvidia Quadro fx 3800) to a projector with HDCP capabilities will it stop pirates from using DVI/HDMI splitters?

    I understand they can use HDFury but this is not a readily avalibale product here so it is ok as long as they can’t use DVI/HDMI splitters.

    Now one last doubt that I have is, how do I notify my graphics card that my content should be played using HDCP? How can the graphics card differentiate between a high value content that needs to use HDCP and normal video which need not use HDCP?

    Please let me know your suggestions

    Thanks
