Understand the Technology First - Current LED TVs - The Truth

Thinking of buying an LED TV, well....Stop! Before you spend in excess of $1500, you need to cut through the jargon and hype to truly understand the technology that you're actually spending your hard earned money on. TV manufacturers and the media are very good at convincing us that the latest products incorporate the most cutting edge technology and are a must have. Lets get real here, to the average consumer most of this jargon is just down right confusing.

A new range of LED TVs that have hit the market with a big buzz. Samsung have crept through the backdoor and have released the 7000 series range boasting LED technology.

That's great...but what is this LED technology thats being boasted?

Current LED TVs - The Truth

The term 'LED' stands for Light Emitting Diode and as you may well know LEDs are used in many of our devices at present, however in terms of the current line of LED TVs, the actual LEDs are used for the backlight of the TV ONLY and not the TV display themselves. If you consider that current TV technology uses CCFL (Cold Cathode Fluorecent Lamps), there is no doubt that an LED backlight is a more efficient form of backlight.

However, the important point here is that the LED television's display is actually LCD (Liquid Crystal Display), it is the backlight only that is made up of LEDs. So there are two major technologies at use here; LCD for the display and LED for the backlight. In essence a more advanced form of LCD TV.

When you compare this technology to a true LED display TV. Displays such as OLED (Organic Light Emitting Diode) will self illuminate, utilizing an internal thin layer of LED for its display only.
The fact that the 'LED TV' term has been used to describe a type of LCD TV is a cunning move on Samsungs part, but genius in terms of marketing, since it capitalises on the current buzz in the TV market of true LED display TVs such as Sony's XEL-1 OLED TV.

LCD TVs with LED Backlights - The Improvements

Now that we've established that this is LCD TV with an LED backlight, lets look at how this new range of TV improves on current TV technology such as plasma and standard LCD in 3 key areas:

1. Picture Quality Quite simply, the picture quality has been improved over standard LCD and Plasma, because the range of colours have increased. The utilization of Light Emitting Diodes as a light source instead of traditional lamps provides a higher contrast ratio because the LED produces blacker blacks and whiter whites, this is the key to achieving quality images on screen.
2. Environment LED Technology consumes less power than current backlight TV technology, making a saving on your energy bills.
3. Slimmer Models. Since no provision for a conventional light source is required, LED TVs can be made ultra thin, this makes for a thin, sleek, more attractive model.

Decisions, Decisions

If you are in the market for a TV now and want a picture quality in advance of current standard LCD and Plasma ranges on the market, then you cannot go far wrong with an LED TV.

However, if you are in no hurray to purchase a television at this present time and require a TV with technology that will keep it at the forefront of cutting edge, in terms of LED technology, OLED TV is the real deal. Laser TV is another option to explore.

Both are emerging technologies and require patience as they find their place in the market with the correct size screens for your home. These TVs may also require you to dig a little deeper into your bank balance.
The moral of the story is to understand the technology behind the product in great detail before you part with your money, the choice is yours.

Dish TV Programming Channels from MPEG 4 Technology

Dish TV programming channels are aired on MPEG 4 Format. Because of this viewers of satellite televisions are getting distortion free images on their television screens. The programs are broadcasted straight away from the geosynchronous satellites directly to the viewer. This is yet another reason that has made satellite television quite popular among people.
About MPEG 4

MPEG 4 is a patented technology that was introduced at the end of the year 1998 and it soon gained immense popularity. This format is used mainly to stream internet media and later on it was introduced for streaming television signals. Today MPEG 4 is recognized as a standard video and audio coding format. MPEG 4 is quite similar to MPEG 1 and MPEG 2 since it shares several features from these two formats. New features have been added later on for make it capable for 3D rendering. The well known codecs such as DivX, Xvid and Nero Digital have now become a part of this amazing compression format.

Previously this audio video compression format was aimed mainly at low bit-rate video communication. But soon the scope of this compression technology got expanded and now it has become the primary tool for multimedia coding. This format is extremely efficient across a wide spectrum of bit-rates, which is from few Kbps up to tens of megabytes per second (Mbps). MPEG 4 is known for enhancing the efficiency of coding and it is even capable of encoding mixed media data such as audio, video and speech.

Since this amazing audio and video compression format is used for streaming television signals, therefore dish TV service providers have decided to adopt this technology to offer maximum TV viewing pleasure. For this purpose the service providers of satellite television have introduced newer receiver models that are compatible with this format. One such receiver model is ViP 622 HDTV DVR receiver.

About ViP 622 HDTV DVR receiver

This is a unique satellite TV receiver that supports both MPEG 2 and MPEG 4 technology. This is a High Definition Receiver that has two tuners named TV1 and TV2. it has a built-in 120 gigabyte hard drive that is capable of storing 100 hours of television program recording. This device allows you to operate it in two modes. One is the Single Mode and the other one is Dual Mode. In single mode you can operate its two HD tuners from a single remote and in dual mode, you can record a TV show while watching another channel.

In this receiver you will be getting two remote controls in which one is a regular infra-red based and the other one is UHF or Ultra High Frequency based. The UHF remote will allow you to control your ViP 622 HDTV DVR receiver from 200 feet irrespective of any obstruction. And the regular IR based remote is even capable of controlling your TV and VCR.

Satellite TV is all about sophisticated technologies. You are getting crystal clear picture and rich surround sound on your television set. Add a feature packed satellite receiver with that and the outcome will be something that can be described only in one word - marvelous.
