Major Components

All video cameras contain 3 major components – the
lens, imager, and recorder. The lens gathers and
focuses the light on the imager, which is normally
a charge coupled device (CCD) or CMOS sensor IC.
Finally, the recorder will encode the video signal
into a form that can be stored. Commonly, the optics
and imager are known as the camera section.

The optic lens is the first component in the camera
section’s light path. The optics normally have one
or more the following adjustments:
1. aperture – controls the amount of light
2. zoom – controls the field of view
3. shutter speed – captures continuous motion
In most consumer units, these adjustments are
automatically controlled by the video camera’s
electronics, normally to maintain constant exposure
onto the imager.

The imager is the “eye” of the camera, housing a
photo sensitive device or devices. The imager works
to convert light into an electronic video signal
through an elaborate electronic process. The
camera lens projects an image to the imager surface,
exposing the photo sensitive array to the light.

The light exposure is then converted into an electrical
charge. Towards the end of the timed exposure, the
imager will convert the accumulated charge into a
continuous analog voltage at the imager’s output
terminals.

The third piece, the recorder, is responsible for
writing the video signal to a recording medium,
such as magnetic videotape. The recording function
involves many steps of signal processing, and
historically, the recording process introduced
some distortion and noise to the stored video,
such that the playback of stored signal may not
retain the same detail as the original live feed.

All but the most primitive of video cameras will
also need to have a recorder controlling section
which will allow you to control the camera. You
can also swich the recorder into playback mode
for reviewing your recorded footage.

The image you recorded doesn’t need to be limited
to what appeared in the view finder. For a
documentation of events such as those used by the
police, the fields of view will overlay such
things as the time and date of the recording along
the top and bottom of the image.

As you can probably tell now, a high definition
video camera is very complex indeed. There are
several other parts involved as well, although the
above are the most important. A HD video camera
is very complex in build, making it something
that is more than worth the time it takes to create.

The Advent And Rise Of High Definition Telvision

A media for viewing moving images along with real sounds had been a distant and ambitious dream for everyone until 1926. during that year, a kind of media was invented.

1926 was the year television was invented. People and fanatics have long been arguing that the television is so far the greatest and most important invention made by mankind.

It can be proven true. Everything was magneted and driven toward television. The economy, and all industries have centered around television. Television is the modern a nd widely used source of news, entertainment and information.

No wonder television is catching all the attention, unlike its media peers, the radio and the newspapers. The challenge of the Internet is posing threat, but television still is up to its sleeve.

The dominance of television as a source of information and entertainment, is expected to lost some long time further. Thus, revenues pouring from ads and sponsorships are likely to be enjoyed by broadcast companies for several more years to come.

That could probably be the reason why technology firms are still focused on developing television sets that are outpacing and making older models obsolete and inferior.

High definition television

High definition television was almost also an impossible dream fro the benevolent TV addict until 1998, when the first high definition television was introduced and launched to the market.

The introduction of high definition television has somehow contributed to the modern day influx of television sets and models. High definition television sets have made the earlier models, especially the widely used and affordable analog television sets, inferior and of low standards.

Indeed, high definition television has set standards of its own in the television manufacturing industry. The first developers of high television sets were envied by competitors, that is why other TV makers have come out with their own versions of high definition television sets.

Unbelievable features

There are a number of incredible features exhibited by high definition television sets. For one, and as a start, the resolution is crystal clear. High definition television sets are made of the finest LCDs or monitors, with the best audio qualities possibly can be integrated in a modern day machine.

Analog TVs can be crystal clear and contenting, but seeing the exceptional quality of image and pictures in high definition television sets will make them comparatively lagging behind and in the most straight-forward word, inferior.

The sound quality of high definition television is equally breath taking. It is like hearing the real and actual sound, only much and way long better.

High definition television sets make up for a more pleasurable and breath taking television viewing experience. There is no arguing to that.

TV signals

Because the technology used in the development and manufacture of high definition television sets is different from the wide used technology used in the making of analog TVs, the signal reception is different.

That could make up one downside to the high definition television emergence. Because most TV networks around the world are basically operating using analog signal transmitters, it would take years before all of them are fully converted into digital signal transmissions.

Digital signal transmissions is the key to high definition television sets. These TVs cannot receive and take in the conventional analog TV signals. Because they are digital, high definition television sets can only accommodate digital TV signals.

Switching of broadcast industries to digital will take years to accomplish. In the US, it is assumed that the switch will be fully implemented by February 2007. it will be until 2009 to 2010 in Australia and the rest of the world is soon to follow suit.

Thus the adoption and full-scale blow up of high definition television industry will take several more years to be realized.
