"IT says 'Video', but
I've only got a DVD player" - a potential buyer studying a poster advertising
"Curious South Cheshire".
AS people are sometimes
confused by the various terms used in connection with videos, here is -
I hope - a useful guide. I am assuming these are the terms that everyone
Video. A video
project or production, such as a documentary or drama.
DVD. Those 12cm
discs that have been "burned" with the video production and are played in a
Machines playing both DVDs and video tape cassettes are
referred to as "combi" or combination players.
The letters DVD used to
stand for Digital Video Disc, but with a wider use for the discs, they
were renamed, Digital Versatile Disc.
VHS tapes/cassettes. (VHS stands
for Video Home Service and is a video cassette format patented by the
firm JVC). This is usually what people think of when they say
"video"; hence the confusion.
The tapes were being phased out and I
haven't seen any in what might be termed "the usual outlets" for a long
time. But you do get the occasional outlet which still caters for tape
users. Try a web search.
Video tapes are used in video cassette recorders (VCRs) for
recording television programmes for later viewing. And I used to have a (large)
camcorder which used them.
PAL (Phase Alternating Line). The
television standard used in the UK among other countries, including
Australia and West Germany. Although it appears to be moving, the
television picture is actually made up of still pictures flashed on to
the screen at a rate of 25 a second. Each is slightly different than the
previous one, giving the illusion of movement. A "gun" fires the
television picture at the back of the television screen in a total of
625 lines for one picture. But it "draws" lines 1, 3, 5, etc, going
down, followed by lines 625, 623, 621, etc, coming up again,
ready to "draw" the next picture.
Television System Committee). The television standard used in the United
States of America, Canada, Japan, etc.
The picture is formed by 525 lines
and 29.7 still pictures a second.
PAL videos produced in this country
have to be converted to NTSC versions for showing in other countries.
SECAM - or, strictly, SeCAM
(Sequential Couleur Avec Memorie - Sequential Colour With Memory). The
television standard used in France, Russia, etc, which like PAL, uses 625 lines.
PAL videos produced in this country have to be converted to SECAM
versions to be sold for showing in other countries.
