I have done a google or two on HDCP and come up with this....

http://www.edn.com/contents/images/209091.pdf

... which outlines how HDCP works and what is involved.

It also lead me onto this....

... as I suspected, to join the club is very expensive.

"The annual fee shall be US $15,000 per year

In addition to the annual fee the adopter shall pay the following=20
device key fees for each order of device keys.

1,000,000 keys =3D US $5,000
100,000 keys =3D US $2,500
10,000 keys =3D US $1,000"

It probably goes some way in explaining why the first available HDMI=20
over CAT5 converters are > $500 per set.

Also found this which might be of interest....

I recently got a nice new 32" JVC CRT with three SCARTS (2 RGB=20
capable) then about three weeks later read on the Tivo forum that=20
Samsung are releasing an 32" HD CRT for the same price (=A3350)

I dont think the people who were selling TiVo realised what a superb=20
product they were selling. It wasnt helped by the fact that TiVo=20
didnt give the shops a subscription for the demo machines so that=20
they could truely show its capabilities :(

I heard somewhere about an HDMI distribution amp that had HDCP on=20
its input and one output but the other outputs were non HDCP HDMI=20
but this unit was allegedly about =A32500
