can't sell a HDTV decoder card nowadays. And HDMI is not only about
encryption but also contains audio encapsulation. And that is an argument
for HDMI vs. DVI... HDCP on a open Linux system is useless anyway.

The driver contains not much more than you would get with I2C-snooping. But
if you want to buy the chip, you need to sign the NDA first...

So what? Wasn't it idea of free Software to get it without paying for it? Or
is there a newly inserted paragraph about hardware vendors to pay something
if they use free SW?

Overall, all this (IMO useless) discussion is only about the HDMI driver
part which is currently (accidently) implemented in the kernel. I can't see
that it's getting any "better" from an OSS standpoint when it's a
closed-source user space program. Get real...
The usual practical "anti-binary" arguments for a PC platform (new mainboard
requires new kernel) don't count here, it's an embedded system. You can't
simply switch the kernel anyway, as it has many additions for the V4L-stuff.

Well, you don't have to buy the card if you would wake up in cold sweat
every once in a while because of the small binary-only part in the kernel.
But IMO you can wait until the end of time for a full open source HDTV card
with HDMI output. If you have the time... ;-)
