        violation of subsection (b) with respect to such copyright
        management information, if the activity that constitutes such
        violation is not intended to induce, enable, facilitate, or
        conceal infringement of a right under this title, and if - 
            (i) the transmission of such information by such person
          would result in a perceptible visual or aural degradation of
          the digital signal; or

          would conflict with -

            section of broadcast stations or cable systems and
