Do you really believe this? How can the HD DVD spec possibly have any bearing on what you do to a signal after it's output from the HD DVD player?
The HD DVD spec requires HDCP for 1080 HDMI output, right? 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? 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.
Let me see if I get this right. The disc is 24p. The decoder generates 24p. The player outputs this in 60i after adding duplicate fields. And you think it is expensive to output the original 24p?
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
. There are a raft of posts here, including from respected insiders, that the current HD DVD spec does not address 1080p24 output in such a way that you can build a compliant player without, at a minimum, ignoring content flags which might impact proper stream decoding (see this
post for one of many credible references). In this
post you acknowledge the spec doesn't fully address issues related to authoring 24p content and that it's being worked on.
If you have 60i PiP, you can butcher it to 24p at encode time in BD
Which isn't an option in HD DVD, since 24p encoding isn't allowed for PiP content, correct?
And if studios wanted, they could choose to author all PiP content in 24p in HD DVD just the same.
Yes, if they wanted to author non-compliant content, and take their chances that all implementations would still handle it properly.
So really, your original argument was to propagate a myth.
No, a myth suggests there is no credible basis for the claims. I've provided credible reference to my claims, unlike your first claim (that the fact you can post-process HD DVD output to 24p proves you can output 24p content directly from a compliant HD DVD player.
