What is a Multi
system VCR?

There are different video standards that are used in
different parts of the world. For example, North America
uses NTSC system; Europe uses PAL and SECAM, while South
America uses PAL-M, PAL-N, PAL and NTSC. Almost every area of the
world has a combination of video standards. Unfortunately none of these
standards are compatible and well matched. Here the utility of a multi system
VCR comes in. it has the ability to play video tapes of different video
standards.

Normally, a multi system VCR permits you to play video tapes
from all over the world, but is not able to convert the video signals.
Therefore, if you are using a NTSC system, a multi system VCR may not allow you
to watch a PAL tape on your NTSC television. A converting multi system VCR is
then required which will convert its video output signal through a video
converter which is in built, so that you can watch a PAL video tape on an NTSC
TV. With an ordinary multi system VCR, you will need to procure an external Ten
lab video converter or a multi system TV. Normally these days the multi system
VCR?s are coming with in built Video Converters. (For your information, a multi
system TV is capable of playing all the video formats like NTSC, PAL and
SECAM.)

On the same fundamentals of multi system VCR, if you apply
an NTSC video input tape into a multi system VCR, it will result in an NTSC
output video signal, and a SECAM tape will result in a SECAM output signal.
Therefore, a multi system VCR will always output whatever type or format of
input you will put into it.

Now the question
arises, how will you view the tapes?

Well, there are a number of ways to execute this. As you
read above, only a multi system VCR alone won't be helpful. Only if the system
has an in built converter, you will not need an external video converter. When
a multi system VCR gives an output of a video signal, what ever it may be (PAL,
SECAM, or NTSC), the video converter will receive the signal and convert it to
whatever video signal you desire. So, if you want to watch a PAL video tape on a
NTSC TV with your multi system VCR, you would have to place the video converter
between the VCR and the TV. In this arrangement, the PAL signal from the VCR
goes into the video converter, gets converted and is outputted as an NTSC
signal, then goes to the TV as a video signal that the TV can display.

However, some multi system VCRs already have the video
converter installed internally so there's no need to purchase an external one.
The disadvantage to these units is that the image quality they produce isn't as
good as a multi system VCR and external video converter combination.

The final possibility is to get a multi system TV/VCR combo.
This solution is not recommended because TV/VCR combos tend to be of low
quality. Many VCRs record an electronic index code at the beginning of each
recording. To scan your recordings on a tape, you press index search. The VCR
then stops at each index mark, and plays back a few seconds of the recording.
Some VCRs even let you go directly to a specific index mark and start playback.

It allows you to search forward or backward through a tape
at a range of fast and slow speeds. Jog control allows you to move the tape
forward or backward frame by frame. These models set their own clock thanks to
a time signal being sent from your local PBS station. This means that you never
have to set the clock initially or reset it after a blackout or brownout. When
power is restored, the VCR will display the correct time. Auto Clock Set is now
found on many mid- to upper-end models.

If you are buying a multi system VCR mainly to record
television broadcasts, then programming is an important thought which should be
given due importance. Except for VCPs (video cassette players), all multi
system VCRs can be programmed at will to record at least one desired program.
The most basic programming proposal uses a built-in clock timer that you set to
start and stop within the next a 24-hour period. More complicated programming
allows you to record several different programs on different channels or a
period of 28 days or more. Other program operations let you record the same
program every day or every week. Many VCRs include VCR Plus+, a simple method
of programming by entering a number listed in TV Guide or many newspapers'
television guides. Some VCR Plus+ models will also change channels on your
cable box via a mouse, blaster, or an infrared transmitter located on the top
of the VCR.

Another characteristic is the Hi-fi sound system that stands
for high-fidelity, or high-quality sound. It is a new true stereo--not the low-pitched
sound that was accessible on VCRs quite a few years ago. If you are thinking of
taking a new VCR or even replacement, then certainly, hi-fi is the one upgrade
feature that you should consider. All movies and videos manufactured now have
hi-fi soundtracks encoded with Dolby Surround system.
