"Freeview HD" will only allow branding, and access to the EPG
data if the output from the box is encrypted with HDCP, and USB recording is encrypted. The EPG data is encoded with a proprietary Huffman table, that you get access to by agreeing to the terms.
There is nothing to stop a manufacturer making a generic DVB-T2 box, without access to the Freeview HD EPG, like August do, and allow you to record unencrypted. Recording onto a PC, and using an external EPG, like XMLTV, or one of the Linux programmes that can decode the Freeview HD EPG, to record the transport stream to your hard drive, makes recording possible.. BUT bearing in mind, the Freeview HD MPEG4 streams are a little non-standard, with HE-AAC audio and p/i switching.
