No product differentiation would exist if the standards orgs spec'ed everything. No CE company would go for such tight restrictions. Same reason why we spec decoders for codecs and not encoders as to leave room for differentiation.
The HD DVD spec requires HDCP for 1080 HDMI output, right?
Most definitely NOT. The HD DVD spec has no mention of HDCP for 1080i HDMI or otherwise.
AACS is the group that cares about copy protection measures for both formats. But even that group does not "spec" HDCP per-se. Instead, it stipulates that for digital outputs, some form of copy protection measure must be in place. In then goes on to approve HDCP as one measure. It could approve other measures in the future from other orgs. One could imagine DisplayPort being deployed for example and still be compliant with AACS. So you see, even here differentiation is allowed and top of mind.
There are aftermarket products which can strip the HDCP from the output. Does that mean I can build a compliant HD DVD player with no HDCP output on HDMI?
You could build an HD DVD player with such hacks or no HDCP support at all and still be fully compliant. But you would not be able to get a license to AACS to decrypt commercial content using it. Your player however can play unprotected HD DVDs just fine.
Of course not. Your argument that you can post-process the HD DVD output to get 24p has absolutely no bearing on whether a compliant HD DVD player can be built which supports 24p output.
As Ben mentioned, there are already software players that can do 24p. If they can do it, and still be logo compliant, then you have no case here.
No, I don't think it's more expensive to output the original 24p, assuming there's nothing in the HD DVD spec (such as what PiP framerates are allowed) which prevents you from simply outputting 24p.
Good that we agree now on 24p not being expensive.
No, a myth suggests there is no credible basis for the claims.
BDA used to claim that only BD could do 1080p. That was a myth and was blown away a few months later with announcement of 1080p HD DVD players. Do you really want to do that now with 24p?
