|This patent is perfectly valid.|
Show me an STB solution currently that has an internet-linked EPG.
As far as I know, TiVo is closest, but it downloads the EPG in a batch and
any "links" to extra data are handled internally, via contracts to get the
EPG information from TV suppliers, not via dynamic viewing of internet content.
Of course it doesn't stop ANY solution like this from being created in Europe.
That's the great thing about US patents :)
