Difference Between SD ,HD Ready and Full HD TV and Set Top Box

In the era of continuous changing technology, we have completely different style and format of viewing TV or any display. Currently we are offered three formats which are SD (standard definition) , HD(High Definition) Ready and Full HD.

Whether buying a TV, Laptop, any Mobile or DTH Set top Box, we get confused which format to select and what is the difference in these three formats.

So here is a comparison between SD, HD Ready and Full HD ,basic difference lies in pixels size

SD (Standard definition) Gadgets are those which can display 480p , means a pixel resolution of 640 x 480 pixels. Standard definition has always 4:3 aspect ratio.

HD Ready Gadgets can display an image from HD signal, HD ready comes with 720 horizontal lines, means a pixel resolution of 1280 x 720 pixels , which is really very great of watching HD videos and HD broadcasting videos. Though HD ready is capable of playing full HD resolution, but sometimes picture may get stuck, and hanging problem can happen.

Full HD gadgets can display 1080 horizontal lines per frame, means a pixel resolution of 1920 x 1080 pixels, Full HD display contains a greater detail of picture and it brings an extreme level of real life detail and perfect experience of watching High definition videos. HD supports 16:9 aspect ratios.

To watch the HD videos, you are required to have HD supported TV, Laptop, mobile or Set Top box. You cannot watch HD videos in standard definition gadgets.

Increasing the pixels will also affects the cost, lower resolution costs less, and higher resolution will cost more.

When we see TV channels using SD Set top box, we experience a great picture quality and find it crystal clear, but now you can imagine the picture quality would be in HD ready and full HD.

Full HD Set top box shows a picture five times clearer than SD Set top box.

REVIEW OF LCD, LED AND PLASMA TV

Tags: LCD TV|LED Tv|Plasma Tv|Difference between LCD , LED and plasma tv|Techniques of LCD Tv , LED Tv and Plasma Tv


Big set up of CRT(Cathode ray tube) is going and a new debate has started between LCD, LED and PLASMA display. Now a days all the makers are working on these three technologies to make them better.

If we talk about technical details then LCD (liquid crystal display), has liquid crystal between the display panel of  Tv which get activated when an electric current is supplied to it.
LED (Light emitting diode) works on same liquid crystal platform but light emitting diode (LED) are used as back light panel of this TV.
PLASMA Tv works on completely different platform, it has sheet of plasma cells which are activated when current is passed through it.


Here is brief discussion on these three Technologies:


LCD TV:

• LCD Tv's are thinner and lighter and provide more sharper and clear picture then CRT Tv
• It has good contrast ratio so better and clear picture
• Talk about viewing angle, when TV is viewed from odd angle, there is loss of color and detail.
• LCD TV's are economical 
• LCD consumes less power if compare with Plasma
• Lifespan is much higer of LCD, so its a long time investment.

LED TV:

LED and LCD  are based on same technology but in LED light emitting diode is used for black lightning. LED is classified on the basis of location of LED in them. If LED is present at the edges, then it is called EDGE LED Tv and if LED is present throughout then it is called Full LED TV.

• LED TV's are more thinner then LCD, so offer better brightness
• LED have better contrast ratio, so better than LCD
• LED has much wider viewing angle, so problem what you faced in LCD , it minimizes
• LED TV's are more expensive than LCD TV's
• LED back light is more  power efficient, so it consumes less power
• It has long lasting life

PLASMA TV:

Plasma display panel is flat display panel used in large display Tv. These are also perfect for viewing motion video on large display.

• PLASMA Tv has best contrast ratio because it have individual plasma cells.so it has much better brightness.
• Watch your TV from any angle, you will not find any difference in quality. it has much wider viewing angle
• PLASMA consumes lot more power than LCD and LED, because every sub pixels on the screen need to be lit.

Every technology has its merits and demerits, you can take decision according to your need.
