From black and white to color, from color to digital to HDTV. Television technology is an ever changing world.
Television has evolved a long way since they were introduced to public.
Decades ago, television sets managed to captivate the hearts of people
by offering something more amazing and inspiring than radio. The
ability to display animation, live moving images from early cartoons to
people displayed inside a small box. Television sets eventually became
a home staple, adopting the nickname the TV.
While early television sets displayed images in black and white , the
concept of the television set soon grew and evolved. Not only did color
television took over the world of home entertainment, but new add ons
emerged pioneered by VHS systems, early video game consoles and one of
the more recent but aging technologies the DVD player.
Color television sets themselves showed and continue to suffer constant
change. As technology changes and advances continued color television
sets evolved from the old round screen to the more recent flat screen
TV sets. Screens changed from round to flat but new screen display
technologies surfaced including CRT, LCD and Plasma.
Enter Digital television and the HDTV revolution
As home entertainment technology continued to evolve along came digital
television; the ability to broadcast and receive television signals
based on numbers rather than frequency waves. And with Digital
television appeared HDTV. HDTV stands for high definition television
sitting on top of the current home television quality scale. These
gadgets have the ability to display breath taking high resolution
images otherwise impossible to be displayed in older analog and current
standard definition digital television sets known as SDTVs.
These television sets have more than just the ability to display
superior image quality, they feature the wide screen aspect ratio of
theaters. Image is just one of the features that is appealing about
HDTV’s sound quality is also impressive since most of them are 5.1
Dolby Digital Surround Sound ready further enhancing the experience by
offering the option of creating a real surround sound audio space
provided that a 5.1 Dolby Digital set of speakers are used, properly
tuned and placed.
One problem with HDTVs is the fact that in order to watch high
definition television you need high definition sources that can include
a HD DVD or Blu-Ray player for movies or an HDTV ready tuner or
converter for broadcast. Which increases the cost of having a complete
High Definition home system even more expensive.
As HDTVs continue to revolutionize digital television , the technical
aspects regarding high definition television continue to confuse
consumers as this technology develops more and more.
