§ 74.790 Permissible service of digital TV translator and LPTV stations.
(a) Digital TV translator stations provide a means whereby the signals
of DTV broadcast stations may be retransmitted to areas in which direct
reception of such DTV stations is unsatisfactory due to distance or
intervening terrain barriers.
(b) Except as provided in paragraph (f) of this section, a digital TV
translator station may be used only to receive the signals of a TV
broadcast or DTV broadcast station, another digital TV translator
station, a TV translator relay station, a television intercity relay
station, a television STL station, or other suitable sources such as a
CARS or common carrier microwave station, for the simultaneous
retransmission of the programs and signals of a TV or DTV broadcast
station. Such retransmissions may be accomplished by any of the
(1) Reception of TV broadcast or DTV broadcast station programs and
signals directly through space and conversion to a different channel by
one of the following transmission modes:
(i) Heterodyne frequency conversion and suitable amplification, subject
to a digital output power limit of 30 watts for transmitters operating
on channels 14-69 and 3 watts for transmitters operating on channels
(ii) Digital signal regeneration (i.e., DTV signal demodulation,
decoding, error processing, encoding, remodulation, and frequency
upconversion) and suitable amplification; or,
(2) Demodulation, remodulation and amplification of TV broadcast or DTV
broadcast station programs and signals received through a microwave
(c) The transmissions of each digital TV translator station shall be
intended for direct reception by the general public, and any other use
shall be incidental thereto. A digital TV translator station shall not
be operated solely for the purpose of relaying signals to one or more
fixed receiving points for retransmission, distribution, or further
(d) Except as provided in (e) and (f) of this section, the technical
characteristics of the retransmitted signals shall not be deliberately
altered so as to hinder reception on consumer DTV broadcast receiving
(e) A digital TV translator station shall not retransmit the programs
and signals of any TV broadcast or DTV broadcast station(s) without the
prior written consent of such station(s). A digital TV translator may
multiplex on its output channel the video program services of two or
more TV broadcast and/or DTV broadcast stations, pursuant to
arrangements with all affected stations, and for this limited purpose,
is permitted to alter a TV broadcast and/or DTV broadcast signal.
(f) A digital TV translator station may transmit locally originated
visual and/or aural messages limited to emergency warnings of imminent
danger, to local public service announcements (PSAs) and to seeking or
acknowledging financial support deemed necessary to the continued
operation of the station. Acknowledgments of financial support may
include identification of the contributors, the size and nature of the
contribution and the advertising messages of the contributors. The
originations concerning financial support and PSAs are limited to 30
seconds each, no more than once per hour. Emergency transmissions shall
be no longer or more frequent than necessary to protect life and
property. Such originations may be accomplished by any technical means
agreed upon between the TV translator and DTV station whose signal is
being retransmitted, but must be capable of being received on consumer
DTV broadcast reception equipment. A digital TV translator shall
modify, as necessary to avoid DTV reception tuning conflicts, the
Program System and Information Protocol (PSIP) information in the DTV
broadcast signal being retransmitted.
(g) A digital LPTV station may operate under the following modes of
(1) For the retransmission of programming of a TV broadcast or DTV
broadcast station, subject to the prior written consent of the station
whose signal is being retransmitted;
(2) For the origination of programming and commercial matter as defined
in § 74.701(l).
(3) Whenever operating, a digital LPTV station must transmit an
over-the-air video program signal at no direct charge to viewers at
least comparable in resolution to that of its associated analog (NTSC)
LPTV station or, in the case of an on-channel digital conversion, that
of its former analog LPTV station.
(4) A digital LPTV station may dynamically alter the bit stream of its
signal to transmit one or more video program services in any
established DTV video format.
(h) A digital LPTV station is not subject to minimum required hours of
operation and may operate in either of the two modes described in
paragraph (g) of this section for any number of hours.
(i) Upon transmitting a signal that meets the requirements of paragraph
(g)(3) of this section, a digital LPTV station may offer services of
any nature, consistent with the public interest, convenience, and
necessity, on an ancillary or supplementary basis in accordance with
the provisions of § 73.624(c) and (g) of this chapter.
(j) A digital LPTV station may not be operated solely for the purpose
of relaying signals to one or more fixed receiving points for
retransmission, distribution or relaying.
(k) A digital LPTV station may receive input signals for transmission
or retransmission by any technical means, including those specified in
paragraph (b) of this section.
