I am not sure if what I want exists or is allowed to exist ( ala HDCP) What I need is a processor that will allow4 video to be displayed as a split screen on a 720p projector via HDMI. The video streams will be a mixture of 480i, 720p (non-HDCP), 1080i ( non-HDCP), 1080i (HDCP) and maybe 1080p. I was looking at the tvone c2-7100 which will do what I want except that it does not support HDCP.

The goal of this system is to be able to view HDCP content full screen at 720p as well as multiple feeds at once quad split screen.

Is the reason I have been unable to find such a processor that by it's nature it violates the terms of HDCP?

TIA

No - nothing there violates the HDCP agreement.
But, the expense of having 4 simultaneous HD processing paths is quite significant. I think that's more likely the reason you can't find one.

You could add 4 HDCP strippers to the one you mentioned and that would work, but there will probably be a solution out there somewhere for the broadcast/commercial arena.
