subject, however, to the following exceptions and limitations.
Where the rules and regulations of the Federal Communications
Commission require a cable system to omit the further transmission
of a particular program and such rules and regulations also permit
the substitution of another program embodying a performance or
display of a work in place of the omitted transmission, or where
such rules and regulations in effect on the date of enactment of this
Act permit a cable system, at its election, to effect such deletion and
substitution of a non-live program or to carry additional programs
not transmitted by primary transmitters within whose local service
area the cable system is located, no value shall be assigned for the
substituted or additional program; where the rules, regulations, or
authorizations of the Federal Communications Commission in effect
on the date of enactment of this Act permit a cable system, at its
election, to omit the further transmission of a particular program
and such rules, regulations, or authorizations also permit the
substitution of another program embodying a performance or display
of a work in place of the omitted transmission, the value assigned
for the substituted or additional program shall be, in the case of a
live program, the value of one full distant signal equivalent
multiplied by a fraction that has as its numerator the number of
days in the year in which such substitution occurs and as its
denominator the number of days in the year. In the case of a station
carried pursuant to the late-night or specialty programing rules of
the Federal Communications Commission, or a station carried on a
part-time basis where full-time carriage is not possible because the
cable system lacks the activated channel capacity to retransmit on a
full-time basis all signals which it is authorized to carry, the
values for independent, network, and noncommercial educational
stations set forth above, as the case may be, shall be multiplied by a
