Airwaves (also called spectrum or the
electromagnetic spectrum): The medium through which radio or television
signals are transmitted. These signals travel through the air,
unlike the signals transmitted by telephone or cable wires. Almost
every household in America has a television that receives free
programming, sent over the airwaves by local TV or radio stations.
A storage or transmission of information
by a variable physical means, such as a shifts in voltage sent
through the electromagnetic spectrum or the vibrations of against
patterns inside the grooves of a vinyl disc, to create physical
(analogous) patterns of pictures or sounds. Standard broadcasting
or the way old "record players" worked before "CD's."
Transmitting electromagnetic signals through
the airwaves over a wide area, as in television or radio. Such
signals may also be transmitted point-to-point, as in microwave
transmission, and are referred to as narrowcasting. 2. Broadcasting
is also referred to as the radio and television broadcast industry.
3. Broadcasters are those who work in the industry. 4. To broadcast
is to participate in a television or radio program. 5. A broadcast
may also be synonymous with a TV or radio program.
Official communication routes. The Federal
Communications Commission designates a channel (or spectrum frequency)
for a radio or television station to ensure that the stations
do not interfere with each others signal. Channels are commonly
known to viewers as the numbers on TV dials corresponding to individual
local stations. Channel assignments vary widely by market: For
example, ABC's affiliate can be Channel 7 in one market, Channel
4 in another. Cable systems may designate a channel on their service
which differs from the channel location given a broadcast station
by the government.
TV-PC convergence (also called convergence):
The fusion of television and PC into a single home appliance.
Much touted by both the computing and broadcasting industries
as a major advance in technology and convenience, it is equally
a stealth device in marketing. Convergence will allow marketers
to track every move you make on the Internet and on TV, resulting
in the transmission of extremely sophisticated advertising to
each and every member of your household.
The sending of data, audio or video messages
by breaking down that information into bits, the smallest units
a computer understands.
Digital TV (DTV)
The next generation in television, DTV
broadcasters will use the language of computers and the Internet
(bits: ones and zeros) to transmit a large amount information
to home TV receivers. Because much more information is sent as
compared to standard analog television, these pictures will be
much sharper and more detailed. DTV broadcasters will also be
able to send additional text, such as sports scores and closed-captioning.
In mid-1997, President Clinton appointed
a 22-member Advisory Committee on the Public Interest Obligations
of Digital Television Broadcasters, which became known as The
Gore Commission. The Commission's primary task was to recommend
obligations for the nation's 1,544 television stations. The Commission's
report was submitted to the President in mid-December 1998.
This terms refers to the practice by which
TV stations split a single digital signal into six or more different
regular channels. TV stations can then generate increased revenue
by using some channels for all of video transmission, voice mail,
paging, data transmission and Internet service.
A concept which holds that, in return
for using the public airwaves free of charge, the broadcasters
is obligated to act as a trustee of public property and do what
is best for the public good. The public has always meant the local
community to which broadcasters are licensed to serve. Interest
has always meant "to benefit the public," as distinct
from programs the public is interested in. Public interest obligations,
for example, are those specific actions broadcasters undertake
in exchange for their free license to repay the public for using
the public airwaves (or broadcast spectrum).
Public Service Announcements (PSA's)
Commercial like announcements providing
advice on an issue of importance, such as Take a Bite Out of Crime,
or Friends Don't Let Friends Drive Drunk, or a fundraising appeal
such as "A Mind is a Terrible Thing To Waste." These
announcements can be highly produced, or simple announcements
of a local event.
