47 CFR § 76.57 - Channel positioning.
(a) At the election of the licensee of a local commercial broadcast television station, and for the purpose of this section, a qualified low power television station, carried in fulfillment of the must-carry obligations, a cable operator shall carry such signal on the cable system channel number on which the local commercial television station is broadcast over the air, or on the channel on which it was carried on July 19, 1985, or on the channel on which it was carried on January 1, 1992.
(b) At the election of the licensee of a qualified local NCE broadcast television station carried in fulfillment of the must-carry obligations, a cable operator shall carry such signal on the cable system channel number on which the qualified NCE television station is broadcast over the air, or on the channel on which it was carried on July 19, 1985.
(c) With respect to digital signals of a television station carried in fulfillment of the must-carry obligations, a cable operator shall carry the information necessary to identify and tune to the broadcast television signal.
(d) Any signal carried in fulfillment of the must-carry obligations may be carried on such other channel number as is mutually agreed upon by the station and the cable operator.
(e) At the time a local commercial station elects must-carry status pursuant to § 76.64, such station shall notify the cable system of its choice of channel position as specified in paragraphs (a), (b), and (d) of this section. A qualified NCE station shall notify the cable system of its choice of channel position when it requests carriage.
(f) Pursuant to § 76.64(f)(3), a local commercial broadcast television station that fails to make an election is deemed a must-carry station. A cable operator shall carry such a television station on the cable system channel number on which the local commercial television station is broadcast over the air, or on the channel on which it was carried on July 19, 1985, or on the channel on which it was carried on January 1, 1992. In the event that none of these specified channel positions is available due to a channel positioning request from a commercial television station affirmatively asserting its must-carry rights or such a request from a qualified local noncommercial educational station, the cable operator shall place the signal of such a television station on a channel of the cable system's choice, so long as that channel is included on the basic service tier.
Any existing agreement for channel position between a local commercial station entitled to must-carry status and a cable operator entered into prior to June 26, 1990, may continue through the expiration of such agreement.
