§ 15.117 TV broadcast receivers.
(a) All TV broadcast receivers shipped in interstate commerce or
imported into the United States, for sale or resale to the public,
shall comply with the provisions of this section, except that
paragraphs (f) and (g) of this section shall not apply to the features
of such sets that provide for reception of digital television signals.
The reference in this section to TV broadcast receivers also includes
devices, such as TV interface devices and set-top devices that are
intended to provide audio-video signals to a video monitor, that
incorporate the tuner portion of a TV broadcast receiver and that are
equipped with an antenna or antenna terminals that can be used for
off-the-air reception of TV broadcast signals, as authorized under part
73 of this chapter.
(b) Until August 31, 2017, TV broadcast receivers shall be capable of
adequately receiving all channels allocated by the Commission to the
television broadcast service. After August 31, 2017, TV broadcast
receivers shall be capable of adequately receiving all channels
allocated by the Commission to the television broadcast service that
broadcast digital signals, buy they need not be capable of receiving
(c) On a given receiver, use of the UHF and VHF tuning systems shall
provide approximately the same degree of tuning accuracy with
approximately the same expenditure of time and effort: Provided,
however, That this requirement will be considered to be met if the need
for routine fine tuning is eliminated on UHF channels.
(1) Basic tuning mechanism. If a TV broadcast receiver is equipped to
provide for repeated access to VHF television channels at discrete
tuning positions, that receiver shall be equipped to provide for
repeated access to a minimum of six UHF television channels at discrete
tuning positions. Unless a discrete tuning position is provided for
each channel allocated to UHF television, each position shall be
readily adjustable to a particular UHF channel by the user without the
use of tools. If 12 or fewer discrete tuning positions are provided,
each position shall be adjustable to receive any channel allocated to
Note: The combination of detented rotary switch and pushbutton controls
is acceptable, provided UHF channels, after their initial selection,
can be accurately tuned with an expenditure of time and effort
approximately the same as that used in accurately tuning VHF channels.
A UHF tuning system comprising five pushbuttons and a separate manual
tuning knob is considered to provide repeated access to six channels at
discrete tuning positions. A one-knob (VHF/UHF) tuning system providing
repeated access to 11 or more discrete tuning positions is also
acceptable, provided each of the tuning positions is readily
adjustable, without the use of tools, to receive any UHF channel.
(2) Tuning controls and channel readout. UHF tuning controls and
channel readout on a given receiver shall be comparable in size,
location, accessibility and legibility to VHF controls and readout on
Note: Differences between UHF and VHF channel readout that follow
directly from the larger number of UHF television channels available
are acceptable if it is clear that a good faith effort to comply with
the provisions of this section has been made.
(d) If equipment and controls that tend to simplify, expedite or
perfect the reception of television signals (e.g., AFC, visual aids,
remote control, or signal seeking capability referred to generally as
tuning aids) are incorporated into the VHF portion of a TV broadcast
receiver, tuning aids of the same type and comparable capability and
quality shall be provided for the UHF portion of that receiver.
(e) If a television receiver has an antenna affixed to the VHF antenna
terminals, it must have an antenna designed for and capable of
receiving all UHF television channels affixed to the UHF antenna
terminals. If a VHF antenna is provided with but not affixed to a
receiver, a UHF antenna shall be provided with the receiver.
(f) The picture sensitivity of a TV broadcast receiver averaged for all
channels between 14 and 69 inclusive shall not be more than 8dB larger
than the peak picture sensitivity of that receiver averaged for all
channels between 2 and 13 inclusive.
(g) The noise figure for any television channel 14 to 69 inclusive
shall not exceed 14 dB. A TV receiver model is considered to comply
with this noise figure if the maximum noise figure for channels 14-69
inclusive of 97.5% of all receivers within that model does not exceed
(1) The responsible party shall measure the noise figure of a number of
UHF channels of the test sample to give reasonable assurance that the
UHF noise figure for each channel complies with the above limit.
(2) The responsible party shall insert in his files a statement
explaining the basis on which it will rely to ensure that at least
97.5% of all production units of the test sample that are manufactured
have a noise figure of no greater than 14 dB.
(4) In the case of a TV tuner built-in as part of a video tape recorder
that uses a power splitter between the antenna terminals of the video
tape recorder and the input terminals of the TV tuner or a TV broadcast
receiver that uses a power splitter between the antenna terminals of
two or more UHF tuners contained within that receiver, 4 dB may be
subtracted from the noise figure measured at the antenna terminals of
the video tape recorder or TV broadcast receiver for determining
compliance of the UHF tuner(s) with the 14 dB noise figure limit.
(h) Digital television reception capability. TV broadcast receivers are
required only to provide useable picture and sound commensurate with
their video and audio capabilities when receiving digital television
(i) Digital television reception requirement. (1) Responsible parties,
as defined in § 2.909 of this chapter, are required to equip with DTV
tuners new TV broadcast receivers that are shipped in interstate
commerce or imported from any foreign country into the United States
and for which they are responsible to comply with the provisions of
this section. For purposes of this section, the term “TV broadcast
receivers” includes other video devices (videocassette recorders
(VCRs), digital video recorders such as hard drive and DVD recorders,
etc.) that receive television signals.
(2) The requirement to include digital television reception capability
in new TV broadcast receivers does not apply to devices such as mobile
telephones and personal digital assistants where such devices do not
include the capability to receive TV service on the frequencies
allocated for broadcast television service.
(j) For a TV broadcast receiver equipped with a cable input selector
switch, the selector switch shall provide, in any of its set positions,
isolation between the antenna and cable input terminals of at least 80
dB from 54 MHz to 216 MHz, at least 60 dB from 216 MHz to 550 MHz and
at least 55 dB from 550 MHz to 806 MHz. The 80 dB standard applies at
216 MHz and the 60 dB standard applies at 550 MHz. In the case of a
selector switch requiring a power source, the required isolation shall
be maintained in the event the device is not connected to a power
source or power is interrupted. An actual switch that can alternate
between reception of cable television service and an antenna is not
required for a TV broadcast receiver, provided compliance with the
isolation requirement specified in this paragraph can be demonstrated
and the circuitry following the antenna input terminal(s) has
sufficient band-width to allow the reception of all TV broadcast
channels authorized under this chapter.
(k) The following requirements apply to all responsible parties, as
defined in § 2.909 of this chapter, and any person that displays or
offers for sale or rent television receiving equipment that is not
capable of receiving, decoding and tuning digital signals.
(1) Such parties and persons shall place conspicuously and in close
proximity to such television broadcast receivers a sign containing, in
clear and conspicuous print, the Consumer Alert disclosure text
required by paragraph (k)(3) of this section. The text should be in a
size of type large enough to be clear, conspicuous and readily legible,
consistent with the dimensions of the equipment and the label. The
information may be printed on a transparent material and affixed to the
screen, if the receiver includes a display, in a manner that is
removable by the consumer and does not obscure the picture, or, if the
receiver does not include a display, in a prominent location on the
device, such as on the top or front of the device, when displayed for
sale, or the information in this format may be displayed separately
immediately adjacent to each television broadcast receiver offered for
sale and clearly associated with the analog-only model to which it
(2) If such parties and persons display or offer for sale or rent such
television broadcast receivers via direct mail, catalog, or electronic
means, they shall prominently display in close proximity to the images
or descriptions of such television broadcast receivers, in clear and
conspicuous print, the Consumer Alert disclosure text required by
paragraph (k)(3) of this section. The text should be in a size large
enough to be clear, conspicuous, and readily legible, consistent with
the dimensions of the advertisement or description.
(3) Consumer alert. This television receiver has only an analog
broadcast tuner and will require a converter box after February 17,
2009, to receive over-the-air broadcasts with an antenna because of the
Nation's transition to digital broadcasting. Analog-only TVs should
continue to work as before with cable and satellite TV services, gaming
consoles, VCRs, DVD players, and similar products. For more
information, call the Federal Communications Commission at
1-888-225-5322 (TTY: 1-888-835-5322) or visit the Commission's digital
television Web site at: http://www.dtv.gov.
