Television: From Wikipedia, the free encyclopedia

Television (often abbreviated to TV, T.V., or more recently, tv;
sometimes called telly, the tube, boob tube, or idiot box in British
English) is a widely used telecommunication system for broadcasting
and receiving moving pictures and sound over a distance. The term may
also be used to refer specifically to a television set, programming
or
television transmission. The word is derived from mixed Latin and
Greek roots, meaning "far sight": Greek tele (τῆλε), far, and Latin
vision, sight (from video, vis- to see, or to view in the first
person).


Since it first became commercially available from the late 1930s, the
television set has become a common household communications device in
homes and institutions, particularly in the first world, as a source
of entertainment and news. Since the 1970s, video recordings on VCR
tapes and later, digital playback systems such as DVDs, have enabled
the television to be used to view recorded movies and other programs.


A television system may be made up of multiple components, so a
screen
which lacks an internal tuner to receive the broadcast signals is
called a monitor rather than a television. A television may be built
to receive different broadcast or video formats, such as high-
definition television, or preferably referred to as (HDTV). HDTV
costs
more that normal TV but is becoming more available.


The end of analog television broadcasting


NTSC
In North America, the basic signal standards since 1941 have been
compatible enough that even the oldest monochrome televisions can
still receive color broadcasts in 2007. However, the United States
Congress has passed a law which requires the cessation of all
conventional television broadcast signals by February 2009. If the
law
is not changed again, then after that date all NTSC standard
televisions, with analog-only tuners, will go dark unless fitted with
digital ATSC tuners, and the spectrum previously occupied by those
analog channels will be auctioned off by the United States' Federal
Communications Commission for other uses. The analog cut-off date has
been changed by Congress in the past.


PAL and SECAM
PAL and SECAM are expected not to be broadcast in Europe and Eurasia
by the mid-2020s. PAL-M may have a similar decommissioning timeline.


The European Union has recommended its members to have closed down
analogue terrestrial television by 2012. Luxembourg and the
Netherlands had already completed their closedowns in 2006, and
Finland and Sweden will have closed down their analogue broadcasts in
2007. Meanwhile, some countries may have difficulties making the 2012
deadline.


Britain started its programme of switching off analogue transmitters
in October 2007. At 2am on Wednesday 17 October 2007 the BBC2
transmitter covering the Whitehaven and Copeland areas (NW England)
was turned off. The remaining four analogue channels cease
broadcasting in the region on Wednesday 14 November. The original
five
channels will then only be available in digital form, alongside some
15 additional free to air channels.
