You can do 4K/25p in HDMI 1.4 (with 225 MHz transmitters). Currently there is no 297MHz
transmitter, just receiver. If you try to do it in a "software way" in FPGA,
you will need HDMI license ($10K annually!)
an opensource implementation exists at :
http://www.adafruit.com/products/609 (device)
https://github.com/bunnie/netv-fpga (fpga code)
Yes, but for those who do not know:
"HDMI input and output ports, compatible with pixclock speeds of 95MHz"
That uses plain LVDS pairs, which go up to 1080Mbit/s, there is
absolutely no way to scale it further up. And there is also an Xilinx
app-note for TMDS implementation (DVI out of box).
The interesting part is however this:
"Video overlay on HDCP encrypted feeds"
Realtime hdcp decryption/encryption, all in LX9 part?
