§ 73.682 TV transmission standards.
(a) Transmission standards. (1) The width of the television broadcast
channel shall be 6 MHz.
(2) The visual carrier frequency shall be nominally 1.25 MHz above the
lower boundary of the channel.
(3) The aural center frequency shall be 4.5 MHz higher than the visual
carrier frequency.
(4) The visual transmission amplitude characteristic shall be in
accordance with the chart designated as Figure 5 of § 73.699: Provided,
however, That for stations operating on Channel 15 through 69 and
employing a transmitter with maximum peak visual power output of 1 kW
or less the visual transmission amplitude characteristic may be in
accordance with the chart designated as Figure 5a of § 73.699.
(5) The chrominance subcarrier frequency is 63/88 times precisely 5 MHz
(3.57954545 . . . MHz). The tolerance is +-10 Hz and the rate of
frequency drift must not exceed 0.1 Hz per second (cycles per second
squared).
(6) For monochrome and color transmissions the number of scanning lines
per frame shall be 525, interlaced two to one in successive fields. The
horizontal scanning frequency shall be 2/455 times the chrominance
subcarrier frequency; this corresponds nominally to 15,750 Hz with an
actual value of 15,734.264 +-0.044 Hz). The vertical scanning frequency
is 2/525 times the horizontal scanning frequency; this corresponds
nominally to 60 Hz (the actual value is 59.94 Hz). For monochrome
transmissions only, the nominal values of line and field frequencies
may be used.
(7) The aspect ratio of the transmitted television picture shall be 4
units horizontally to 3 units vertically.
(8) During active scanning intervals, the scene shall be scanned from
left to right horizontally and from top to bottom vertically, at
uniform velocities.
(9) A carrier shall be modulated within a single television channel for
both picture and synchronizing signals. The two signals comprise
different modulation ranges in amplitude in accordance with the
following:
(i) Monochrome transmissions shall comply with synchronizing waveform
specifications in Figure 7 of § 73.699.
(ii) Color transmissions shall comply with the synchronizing waveform
specifications in Figure 6 of § 73.699.
(iii) All stations operating on Channels 2 through 14 and those
stations operating on Channels 15 through 69 licensed for a peak visual
transmitter output power greater than one kW shall comply with the
picture transmission amplitude characteristics shown in Figure 5 of
§ 73.699.
(iv) Stations operating on Channels 15 through 69 licensed for a peak
visual transmitter output power of one kW or less shall comply with the
picture transmission amplitude characteristic shown in Figure 5 or 5a
of § 73.699.
(10) A decrease in initial light intensity shall cause an increase in
radiated power (negative transmission).
(11) The reference black level shall be represented by a definite
carrier level, independent of light and shade in the picture.
(12) The blanking level shall be transmitted at 75+-2.5 percent of the
peak carrier level.
(13) The reference white level of the luminance signal shall be
12.5+-2.5 percent of the peak carrier level.
(14) It shall be standard to employ horizontal polarization. However,
circular or elliptical polarization may be employed if desired, in
which case clockwise (right hand) rotation, as defined in the IEEE
Standard Definition 42A65-3E2, and transmission of the horizontal and
vertical components in time and space quadrature shall be used. For
either omnidirectional or directional antennas the licensed effective
radiated power of the vertically polarized component may not exceed the
licensed effective radiated power of the horizontally polarized
component. For directional antennas, the maximum effective radiated
power of the vertically polarized component shall not exceed the
maximum effective radiated power of the horizontally polarized
component in any specified horizontal or vertical direction.
(15) The effective radiated power of the aural transmitter must not
exceed 22% of the peak radiated power of the visual transmitter.
(16) The peak-to-peak variation of transmitter output within one frame
of video signal due to all causes, including hum, noise, and
low-frequency response, measured at both scanning synchronizing peak
and blanking level, shall not exceed 5 percent of the average scanning
synchronizing peak signal amplitude. This provision is subject to
change but is considered the best practice under the present state of
the art. It will not be enforced pending a further determination
thereof.
(17) The reference black level shall be separated from the blanking
level by the setup interval, which shall be 7.5+-2.5 percent of the
video range from blanking level to the reference white level.
(18) For monochrome transmission, the transmitter output shall vary in
substantially inverse logarithmic relation to the brightness of the
subject. No tolerances are set at this time. This provision is subject
to change but is considered the best practice under the present state
of the art. It will not be enforced pending a further determination
thereof.
(19) The color picture signal shall correspond to a luminance component
transmitted as amplitude modulation of the picture carrier and a
simultaneous pair of chrominance components transmitted as the
amplitude modulation sidebands of a pair of suppressed subcarriers in
quadrature.
(20) Equation of complete color signal.
(i) The color picture signal has the following composition:
EM=EY'+[EQ' sin (wt+33DEG)+EI' cos (wt+33DEG)]
Where:
EQ'=0.41(EB' -EY')+0.48(ER' -EY').
EI'= -0.27(EB' -EY')+0.74(ER' -EY').
EY'=0.30ER'+0.59EG'+0. -1EB'.
For color-difference frequencies below 500 kHz (see (iii) below), the
signal can be represented by:
EM=EY'+[(1/1.14)[(1/1.78)(EB' -EY') sin wt+(ER' -EY') cos wt]]
(ii) The symbols in paragraph (a)(20)(i) of this section have the
following significance:
EM is the total video voltage, corresponding to the scanning of a
particular picture element, applied to the modulator of the picture
transmitter.
EY' is the gamma-corrected voltage of the monochrome (black-and-white)
portion of the color picture signal, corresponding to the given picture
element.
Note: Forming of the high frequency portion of the monochrome signal in
a different manner is permissible and may in fact be desirable in order
to improve the sharpness on saturated colors.
EQ' and EI' are the amplitudes of two orthogonal components of the
chrominance signal corresponding respectively to narrow-band and
wide-band axes.
ER', EG', and EB' are the gamma-corrected voltages corresponding to
red, green, and blue signals during the scanning of the given picture
element.
w is the angular frequency and is 2 times the frequency of the
chrominance subcarrier.
The portion of each expression between brackets in (i) represents the
chrominance subcarrier signal which carries the chrominance
information.
The phase reference in the EM equation in (i) is the phase of the
burst+180DEG, as shown in Figure 8 of § 73.699. The burst corresponds
to amplitude modulation of a continuous sine wave.
(iii) The equivalent bandwidth assigned prior to modulation to the
color difference signals EQ' and EI' are as follows:
Q-channel bandwidth:
At 400 kHz less than 2 dB down.
At 500 kHz less than 6 dB down.
At 600 kHz at least 6 dB down.
I-channel bandwidth:
At 1.3 MHz less than 2 dB down.
At 3.6 MHz at least 20 dB down.
(iv) The gamma corrected voltages ER', EG', and EB' are suitable for a
color picture tube having primary colors with the following
chromaticities in the CIE system of specification:
x y
Red (R) 0.67 0.33
Green (G) 0.21 0.71
Blue (B) 0.14 0.08
and having a transfer gradient (gamma exponent) of 2.2 associated with
each primary color. The voltages ER', EG', and EB' may be respectively
of the form ER1/g, EG1/g, and EB1/g although other forms may be used
with advances in the state of the art.
Note: At the present state of the art it is considered inadvisable to
set a tolerance on the value of gamma and correspondingly this portion
of the specification will not be enforced.
(v) The radiated chrominance subcarrier shall vanish on the reference
white of the scene.
Note: The numerical values of the signal specification assume that this
condition will be reproduced as CIE Illuminant C (x=0.310, y=0.316).
(vi) EY', EQ', EI', and the components of these signals shall match
each other in time to 0.05 usecs.
(vii) The angles of the subcarrier measured with respect to the burst
phase, when reproducing saturated primaries and their complements at 75
percent of full amplitude, shall be within +-10DEG and their amplitudes
shall be within +-20 percent of the values specified above. The ratios
of the measured amplitudes of the subcarrier to the luminance signal
for the same saturated primaries and their complements shall fall
between the limits of 0.8 and 1.2 of the values specified for their
ratios. Closer tolerances may prove to be practicable and desirable
with advance in the art.
(21) The interval beginning with line 17 and continuing through line 20
of the vertical blanking interval of each field may be used for the
transmission of test signals, cue and control signals, and
identification signals, subject to the conditions and restrictions set
forth below. Test signals may include signals designed to check the
performance of the overall transmission system or its individual
components. Cue and control signals shall be related to the operation
of the TV broadcast station. Identification signals may be transmitted
to identify the broadcast material or its source, and the date and time
of its origination. Figures 6 and 7 of § 73.699 identify the numbered
lines referred to in this paragraph.
(i) Modulation of the television transmitter by such signals shall be
confined to the area between the reference white level and the blanking
level, except where test signals include chrominance subcarrier
frequencies, in which case positive excursions of chrominance
components may exceed reference white, and negative excursions may
extend into the synchronizing area. In no case may the modulation
excursions produced by test signals extend beyond peak-of-sync, or to
zero carrier level.
(ii) The use of such signals shall not result in significant
degradation of the program transmission of the television broadcast
station, nor produce emission outside of the frequency band occupied
for normal program transmissions.
(iii) Such signals may not be transmitted during that portion of each
line devoted to horizontal blanking.
(iv) Regardless of other provisions of this paragraph, after June 30,
1994, Line 19, in each field, may be used only for the transmission of
the ghost-canceling reference signal described in OET Bulletin No. 68,
which is available from the FCC Warehouse, 9300 East Hampton Drive,
Capitol Heights, MD 20743. Notwithstanding the modulation limits
contained in paragraph (a)(23)(i) of this section, the vertical
interval reference signal formerly permitted on Line 19 and described
in Figure 16 of § 73.699, may be transmitted on any of lines 10 through
16 without specific Commission authorization, subject to the conditions
contained in paragraphs (a)(21)(ii) and (a)(22)(ii) of this section.
(22)(i) Line 21, in each field, may be used for the transmission of a
program-related data signal which, when decoded, provides a visual
depiction of information simultaneously being presented on the aural
channel (captions). Line 21, field 2 may be used for transmission of a
program-related data signal which, when decoded, identifies a rating
level associated with the current program. Such data signals shall
conform to the format described in figure 17 of § 73.699 of this
chapter, and may be transmitted during all periods of regular
operation. On a space available basis, line 21 field 2 may also be used
for text-mode data and extended data service information.
Note: The signals on Fields 1 and 2 shall be distinct data streams, for
example, to supply captions in different languages or at different
reading levels.
(ii) At times when Line 21 is not being used to transmit a program
related data signal, data signals which are not program related may be
transmitted, Provided: the same data format is used and the information
to be displayed is of a broadcast nature.
(iii) The use of Line 21 for transmission of other data signals
conforming to other formats may be used subject to prior authorization
by the Commission.
(iv) The data signal shall cause no significant degradation to any
portion of the visual signal nor produce emissions outside the
authorized television channel.
(v) Transmission of visual emergency messages pursuant to § 73.1250
shall take precedence and shall be cause for interrupting transmission
of data signals permitted under this paragraph.
(23) Specific scanning lines in the vertical blanking interval may be
used for the purpose of transmitting telecommunications signals in
accordance with § 73.646, subject to certain conditions:
(i) Telecommunications may be transmitted on Lines 10-18 and 20, all of
Field 2 and Field 1. Modulation level shall not exceed 70 IRE on lines
10, 11, and 12; and, 80 IRE on lines 13-18 and 20.
(ii) No observable degradation may be caused to any portion of the
visual or aural signals.
(iii) Telecommunications signals must not produce emissions outside the
authorized television channel bandwidth. Digital data pulses must be
shaped to limit spectral energy to the nominal video baseband.
(iv) Transmission of emergency visual messages pursuant to § 73.1250
must take precedence over, and shall be cause for interrupting, a
service such as teletext that provides a visual depiction of
information simultaneously transmitted on the aural channel.
(v) A reference pulse for a decoder associated adaptive equalizer
filter designed to improve the decoding of telecommunications signals
may be inserted on any portion of the vertical blanking interval
authorized for data service, in accordance with the signal levels set
forth in paragraph (a)(23)(i) of this section.
(vi) All lines authorized for telecommunications transmissions may be
used for other purposes upon prior approval by the Commission.
(24) Licensees and permittees of TV broadcast and low power TV stations
may insert non-video data into the active video portion of their TV
transmission, subject to certain conditions:
(i) The active video portion of the visual signal begins with line 22
and continues through the end of each field, except it does not include
that portion of each line devoted to horizontal blanking. Figures 6 and
7 of § 73.699 identify the numbered line referred to in this paragraph;
(ii) Inserted non-video data may be used for the purpose of
transmitting a telecommunications service in accordance with § 73.646.
In addition to a telecommunications service, non-video data can be used
to enhance the station's broadcast program service or for purposes
related to station operations. Signals relating to the operation of TV
stations include, but are not limited to program or source
identification, relay of broadcast materials to other stations, remote
cueing and order messages, and control and telemetry signals for the
transmitting system; and
(iii) A station may only use systems for inserting non-video
information that have been approved in advance by the Commission. The
criteria for advance approval of systems are as follows:
(A) The use of such signals shall not result in significant degradation
to any portion of the visual, aural, or program-related data signals of
the television broadcast station;
(B) No increase in width of the television broadcast channel (6 MHz) is
permitted. Emissions outside the authorized television channel must not
exceed the limitations given in § 73.687(e). Interference to reception
of television service either of co-channel or adjacent channel stations
must not increase over that resulting from the transmission of
programming without inserted data; and
(C) Where required, system receiving or decoding devices must meet the
TV interface device provisions of Part 15, Subpart H of this chapter.
(iv) No protection from interference of any kind will be afforded to
reception of inserted non-video data.
(v) Upon request by an authorized representative of the Commission, the
licensee of a TV station transmitting encoded programming must make
available a receiving decoder to the Commission to carry out its
regulatory responsibilities.
(b) Subscription TV technical systems. The FCC may specify, as part of
the advance approval of the technical system for transmitting encoded
subscription programming, deviations from the power determination
procedures, operating power levels, aural or video baseband signals,
modulation levels or other characteristics of the transmitted signal as
otherwise specified in this Subpart. Any decision to approve such
operating deviations shall be solely at the discretion of the FCC.
(c) TV multiplex subcarrier/stereophonic aural transmission standards.
(1) The modulating signal for the main channel shall consist of the sum
of the stereophonic (biphonic, quadraphonic, etc.) input signals.
(2) The instantaneous frequency of the baseband stereophonic subcarrier
must at all times be within the range 15 kHz to 120 kHz. Either
amplitude or frequency modulation of the stereophonic subcarrier may be
used.
(3) One or more pilot subcarriers between 16 kHz and 120 kHz may be
used to switch a TV receiver between the stereophonic and monophonic
reception modes or to activate a stereophonic audio indicator light,
and one or more subcarriers between 15 kHz and 120 kHz may be used for
any other authorized purpose; except that stations employing the BTSC
system of stereophonic sound transmission and audio processing may
transmit a pilot subcarrier at 15,734 Hz, +-2 Hz. Other methods of
multiplex subcarrier or stereophonic aural transmission systems must
limit energy at 15,734 Hz, +-20 Hz, to no more than +-0.125 kHz aural
carrier deviation.
(4) Aural baseband information above 120 kHz must be attenuated 40 dB
referenced to 25 kHz main channel deviation of the aural carrier.
(5) For required transmitter performance, all of the requirements of
§ 73.687(b) shall apply to the main channel, with the transmitter in
the multiplex subcarrier or stereophonic aural mode.
(6) For electrical performance standards of the transmitter, the
requirements of § 73.687(b) apply to the main channel.
(7) Multiplex subcarrier or stereophonic aural transmission systems
must be capable of producing and must not exceed +-25 kHz main channel
deviation of the aural carrier.
(8) The arithmetic sum of non-multiphonic baseband signals between 15
kHz and 120 kHz must not exceed +-50 kHz deviation of the aural
carrier.
(9) Total modulation of the aural carrier must not exceed +-75 kHz.
(d) Digital broadcast television transmission standard. Effective
October 11, 2011 transmission of digital broadcast television (DTV)
signals shall comply with the standards for such transmissions set
forth in ATSC A/52: "ATSC Standard Digital Audio Compression (AC-3)",
ATSC A/53, Parts 1-4 and 6: 2007 "ATSC Digital Television Standard,"
(January 3, 2007), and ATSC A/53 Part 5:2010 "ATSC Digital Television
Standard: Part 5--AC-3 Audio System Characteristic," (July 6, 2010),
except for section 6.1.2 ("Compression Format Constraints") of A/53
Part 4: 2007 ("MPEG-2 Video Systems Characteristics") and the phrase
"see Table 6.2" in section 6.1.1 Table 6.1 and section 6.1.3 Table 6.3,
and ATSC A/65C: "ATSC Program and System Information Protocol for
Terrestrial Broadcast and Cable, Revision C With Amendment No. 1 dated
May 9, 2006," (January 2, 2006) (all standards incorporated by
reference, see § 73.8000). Although not incorporated by reference,
licensees may also consult ATSC A/54A: "Recommended Practice: Guide to
Use of the ATSC Digital Television Standard, including Corrigendum No.
1," (December 4, 2003, Corrigendum No. 1 dated December 20, 2006, and
ATSC A/69: "Recommended Practice PSIP Implementation Guidelines for
Broadcasters," (June 25, 2002) (Secs. 4, 5, 303, 48 Stat., as amended,
1066, 1068, 1082 (47 U.S.C. 154, 155, 303)). ATSC A/54A and ATSC A/69
are available from Advanced Television Systems Committee (ATSC), 1750 K
Street, NW., Suite 1200, Washington, DC 20006, or at the ATSC Web site:
http://www.atsc.org/standards.html.
(e) Transmission of commercial advertisements by television broadcast
station. (1) Mandatory compliance with ATSC A/85 RP. Effective December
13, 2012, television broadcast stations must comply with the ATSC A/85
RP incorporated by reference, see § 73.8000), insofar as it concerns
the transmission of commercial advertisements.
(2) Commercials inserted by station. A television broadcast station
that installs, utilizes, and maintains in a commercially reasonable
manner the equipment and associated software to comply with ATSC A/85
RP shall be deemed in compliance with respect to locally inserted
commercials, which for the purposes of this provision are commercial
advertisements added to a programming stream by a station prior to or
at the time of transmission to viewers. In order to be considered to
have installed, utilized and maintained the equipment and associated
software in a commercially reasonable manner, a television broadcast
station must:
(i) Install, maintain and utilize equipment to properly measure the
loudness of the content and to ensure that the dialnorm metadata value
correctly matches the loudness of the content when encoding the audio
into AC-3 for transmitting the content to the consumer;
(ii) Provide records showing the consistent and ongoing use of this
equipment in the regular course of business and demonstrating that the
equipment has undergone commercially reasonable periodic maintenance
and testing to ensure its continued proper operation;
(iii) Certify that it either has no actual knowledge of a violation of
the ATSC A/85 RP, or that any violation of which it has become aware
has been corrected promptly upon becoming aware of such a violation;
and
(iv) Certify that its own transmission equipment is not at fault for
any pattern or trend of complaints.
(3) Embedded commercials--safe harbor. With respect to embedded
commercials, which, for the purposes of this provision, are those
commercial advertisements placed into the programming stream by a third
party (i.e., programmer) and passed through by the station to viewers,
a television broadcast station must certify that its own transmission
equipment is not at fault for any pattern or trend of complaints, and
may demonstrate compliance with the ATSC A/85 RP through one of the
following methods:
(i) Relying on a network's or other programmer's certification of
compliance with the ATSC A/85 RP with respect to commercial
programming, provided that:
(A) The certification is widely available by Web site or other means to
any television broadcast station, cable operator, or multichannel video
programming distributor that transmits that programming; and
(B) The television broadcast station has no reason to believe that the
certification is false; and
(C) The television broadcast station performs a spot check, as defined
in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on programming in response
to an enforcement inquiry concerning a pattern or trend of complaints
regarding commercials contained in that programming.
(ii) If transmitting any programming that is not certified as described
in § 73.682(e)(3)(i), a television broadcast station that had more than
$14,000,000 in annual receipts for the calendar year 2011 must perform
annual spot checks, as defined in § 73.682(e)(3)(iv)(A), (B), (C), and
(E), of all the non-certified commercial programming it receives from a
network or other programmer and perform a spot check, as defined in
§ 73.682(e)(3)(iv)(A), (B), (D), and (E), on programming in response to
an enforcement inquiry concerning a pattern or trend of complaints
regarding commercials contained in that programming;
(iii) A television broadcast station that had $14,000,000 or less in
annual receipts for the year 2011 need not perform annual spot checks
but must perform a spot check, as defined in § 73.682(e)(3)(iv)(A),
(B), (D), and (E), on programming in response to an enforcement inquiry
concerning a pattern or trend of complaints regarding commercials
contained in that programming.
(iv) For purposes of this section, a "spot check" of embedded
commercials requires monitoring 24 uninterrupted hours of programming
with an audio loudness meter employing the measurement technique
specified in the ATSC A/85 RP, and reviewing the records from that
monitoring to detect any commercials transmitted in violation of the
ATSC A/85 RP. The television broadcast station must not inform the
network or programmer of the spot check prior to performing it.
(A) Spot-checking must be conducted after the signal has passed through
the television broadcast station's processing equipment (e.g., at the
output of a television receiver). If a problem is found, the television
broadcast station must determine the source of the noncompliance.
(B) To be considered valid, the television broadcast station must
demonstrate appropriate maintenance records for the audio loudness
meter.
(C) With reference to the annual "safe harbor" spot check in
§ 73.682(e)(3)(ii):
(1) To be considered valid, the television broadcast station must
demonstrate, at the time of any enforcement inquiry, that appropriate
spot checks had been ongoing.
(2) If there is no single 24 hour period in which all programmers of a
given program stream are represented, an annual spot check may consist
of a series of loudness measurements over the course of a 7 day period,
totaling no fewer than 24 hours, that measure at least one program, in
its entirety, provided by each non-certified programmer that supplies
programming for that program stream.
(3) If annual spot checks are performed for two consecutive years
without finding evidence of noncompliance with the ATSC A/85 RP, no
further annual spot checks are required to remain in the safe harbor
for existing programming.
(4) Non-certified program streams must be spot-checked annually using
the approach described in this section. If annual spot checks of the
program stream are performed for two consecutive years without finding
evidence of noncompliance with the ATSC A/85 RP, no further annual spot
checks are required to remain in the safe harbor for that program
stream.
(5) Even after the two year period for annual spot checks, if a spot
check shows noncompliance on a non-certified program stream, the
station must once again perform annual spot checks of that program
stream to be in the safe harbor for that programming. If these renewed
annual spot checks are performed for two consecutive years without
finding additional evidence of noncompliance with the ATSC A/85 RP, no
further annual spot checks are required to remain in the safe harbor
for that program stream.
(D) With reference to the spot checks in response to an enforcement
inquiry pursuant to § 73.682(e)(3)(i)(C), (2), or (3):
(1) If notified of a pattern or trend of complaints, the television
broadcast station must perform the 24-hour spot check of the program
stream at issue within 30 days or as otherwise specified by the
Enforcement Bureau; and
(2) If the spot check reveals actual compliance, the television
broadcast station must notify the Commission in its response to the
enforcement inquiry.
(E) If any spot check shows noncompliance with the ATSC A/85 RP, the
television station must notify the Commission and the network or
programmer within 7 days, direct the programmer's attention to any
relevant complaints, and must perform a follow-up spot check within 30
days of providing such notice. The station must notify the Commission
and the network or programmer of the results of the follow-up spot
check. Notice to the Federal Communications Commission must be provided
to the Chief, Investigations and Hearings Division, Enforcement Bureau,
or as otherwise directed in a Letter of Inquiry to which the station is
responding.
(1) If the follow-up spot check shows compliance with the ATSC A/85 RP,
the station remains in the safe harbor for that program stream.
(2) If the follow-up spot check shows noncompliance with the ATSC A/85
RP, the station will not be in the safe harbor with respect to
commercials contained in the program stream for which the spot check
showed noncompliance until a subsequent spot check shows that the
program stream is in compliance.
(4) Use of a real-time processor. A television broadcast station that
installs, maintains and utilizes a real-time processor in a
commercially reasonable manner will be deemed in compliance with the
ATSC A/85 RP with regard to any commercial advertisements on which it
uses such a processor, so long as it also:
(i) Provides records showing the consistent and ongoing use of this
equipment in the regular course of business and demonstrating that the
equipment has undergone commercially reasonable periodic maintenance
and testing to ensure its continued proper operation;
(ii) Certifies that it either has no actual knowledge of a violation of
the ATSC A/85 RP, or that any violation of which it has become aware
has been corrected promptly upon becoming aware of such a violation;
and
(iii) Certifies that its own transmission equipment is not at fault for
any pattern or trend of complaints.
(5) Commercials locally inserted by a station's agent--safe harbor.
With respect to commercials locally inserted, which for the purposes of
this provision are commercial advertisements added to a programming
stream for the television broadcast station by a third party after it
has been received from the programmer but prior to or at the time of
transmission to viewers, a station may demonstrate compliance with the
ATSC A/85 RP by relying on the third party local inserter's
certification of compliance with the ATSC A/85 RP, provided that:
(i) The television broadcast station has no reason to believe that the
certification is false;
(ii) The television broadcast station certifies that its own
transmission equipment is not at fault for any pattern or trend of
complaints; and
(iii) The television broadcast station performs a spot check, as
defined in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on the programming
at issue in response to an enforcement inquiry concerning a pattern or
trend of complaints regarding commercials inserted by that third party.
(6) Instead of demonstrating compliance pursuant to paragraphs (e)(2)
through (5) of this section, a station may demonstrate compliance with
paragraph (e)(1) of this section in response to an enforcement inquiry
prompted by a pattern or trend of complaints by demonstrating actual
compliance with ATSC A/85 RP with regard to the commercial
advertisements that are the subject of the inquiry, and certifying that
its own transmission equipment is not at fault for any such pattern or
trend of complaints.
Note to § 73.682: For additional information regarding this
requirement, see Implementation of the Commercial Advertisement
Loudness Mitigation (CALM) Act, FCC 11-182.
