In 1996 I borrowed a DVB encoder and receiver and tried to hack it
to send my own digital video.  There was a showstopper problem having
to do with the encryption.  Even if you wanted to send video in the
clear, you still needed authorization of the receiver.  To get the
passcodes, you had to pay a big licensing fee to the holder of the
encryption technology rights.  Is there a workaround for this?
