Again, the licensing cost is not on the IC but on HDMI (and optionally
HDCP) as such. You need that same licensing even to build an A10 device
with HDMI output.

It is quite likely you can get one or two HDMI receiver ICs as samples
without having to proove you have a valid HDMI license. But in any
volume purchase of such ICs you are likely to need to proove that you
have an HDMI license for the use of those components.

You quite likely need that anyway to control an DVI/HDMI receiver / LCD
driver. Most are not 100% self-sustained in adopting to the various
kinds of signals you may see over DVI or HDMI.
