Not specifically FreeSat.  I got the general MHEG-5 Broadcast Profile
(ETSI ES 202 184 V2.2.1 (2011-03)), which contains the Interaction
Channel stuff, from www.etsi.org.  The doc is free if you register and
only need a few downloads.

I haven't seen any docs specifically relating to FreeSat extensions.
The patch for the type 5 bitmap was developed by observation, not from a
spec.

I presume there's some kind of NDA that the BBC/FreeSat have in place
for STB manufacturers and/or suppliers of libraries.  I guess that this
also relates to the decryption keys for the various FreeSat services and
the enforcement of DRM.  See

I'm not sure how applicable these changes would be to FreeView.  I would
have thought that the BBC would want an equivalent service for both.
But as I live in France I've not been able to try FreeView.
