TVs have come a long way
from black-and –white with few channels to color with wide range of channels
to HDTVs (High Definition Televisions) and to Smart TVs . As the
technology advancement has changed the quality of TV viewing, the requirement
for high-featured TV has grown. Whether Watching TV is national pastime
or not, and without arguing its influence on children, here are few tips
for better TV viewing .
HDTV: HDTVs are those that provide high-performance mainly in terms of
its picture quality and sound besides other things more than normal TVs. There
are various types of them according to how they produce picture on screen such
as Plasmas(uses charged ions ), LEDs(Light Emitting Diodes), and
LCDs(Liquid Crystal Display). The interesting comparison among these are as
follows:
According to
Webopedia.com, LED TVs are the most energy efficient among the three, also LEDs
have slim panels and easier wall mounting. LEDs are good for viewing in dark or
dimly-lit rooms and for wider viewing angels (more people can watch).
Plasma TVs have thick and heavy
panels, least energy efficient with widest viewing angels and not available
under 42” screen size.
LCD TVs are more energy
efficient than plasma TVs with availability of wide range of screen size.
Although three types of
TVs are similar in producing colourful pictures, there are some differences as
described above which you may consider in buying a TV.
Picture Quality: 1080p (progressive)and 720p are the standard
for defining picture quality, also called as “resolution” . It refers to number
of pixels represented for a picture, 1,080 vertical pixels by 1920
horizontal pixels or column of pixels. High-definition signals have 1080p
format which is highest. Higher the
resolution higher the picture definition as there are more lines of information,
the level of detail can be much more precise. Not all channels are in HD mode
and HD channels are pricey.
HDMI: High Definition Multimedia Interface point
or input on HDTV provides interface to computer and other devices such as the home theater,
set top box , gaming systems, and blu-ray players. Internet can be accessed via this port.
Set Top Box: ““Set top box” (STB) is a device, which is connected to a
television set at the consumer premises and which allows a consumer to view
encrypted channels of his choice. The basic function of the set top box is to
decrypt the channels and to convert the digital signals into analog mode for
viewing on television sets. A smart card or viewing card is a part of set top
box which allow only those channels to be viewed which are subscribed by the
consumer and authorised by the service provider” as mentioned by Trai.gov.in.
This is in particular to STBs which are now mandatory to use in India. This STBs are used for DAS(digitally
addressable system) and not for DTH system.What it means for your TV…is a
question. STBs may or may not provide timings of programs and other related functionalities. Without STB, channels can not be viewed on TV.

Smart TV
Smart TVs:
These are extended version of HDTVs with processor to provide Internet
browsing, Apps(Twitter, YouTube and others) and other functionalities(gesture
controlled, not remote controlled; 3D effects, etc.).There are devices by which any TV can be turned
into Smart TV(Akai smart box) which provides emailing, web browsing and so on. Whether
you want to watch TV with Internet or standalone is a matter of personal
choice.
Today’s TVs are more than passive
viewing and with new features added from time to time as tech is progressing rapidly, it is now
possible to experience infotainment at whole new level.
