Why Should You Purchase A Magnavox HDTV

It is “high” for you to start looking into the Magnavox HDTV with its crystal clear picture that has clarity never seen before.  Soon all TV stations will be only available in HDTV.  It would be wise to start doing your homework on the various HDTV TV’s on the market.

What is HDTV?   High-definition television (HDTV) is a digital television broadcasting system with higher resolution than traditional television systems (SDTV) . HDTV is digitally broadcast digital television (DTV) that requires less bandwidth.

On February 17, 2009 the US intends to terminate all full-power analog broadcasting (some smaller local stations have later deadlines), with both standard definition TV (SDTV) and HDTV being allowed.  This will require all new televisions to be manufactured with HDTV capability.  There are adapters that can be purchased to trasform the analog set to HDTV.

With LED HDTV, the resolution is the primary reason for the change.  The clarity is so incredible that people watching sporting events, concerts, movies, or virtually any show will be amazed at how incredible the picture becomes.  For example, the number of visible lines seen with standard programming is 480 but with a LCD high definition television, that number jumps to 1,080.

Most cities in the US with major network stations broadcast over the air in HD. To receive this signal an HD tuner is required.  The new Magnavox HDTV has an HD tuner built in. For HDTV televisions without a built in HD tuner, a separate set-top HD tuner box can be rented from a cable or satellite company or a Magnavox HD tuner box can be purchased.

HDTV broadcast systems are described in the following three ways: 1. The number of lines in the vertical display resolution. 2. The scanning system: Progressive Scanning (noted with a “p”) or Interlaced Scanning (noted with an “I”.)   Progressive scanning simply draws a complete image frame (all the lines) per image.   Interlaced scanning draws a partial image field (every second line) during a first pass, then fills-in the remaining lines during a second pass. 3. The number of frames per second or fields per second.

Of course HDTV has outstanding resolution due to the frame or field rate.  When shopping for an LCD look for the specified resolution rate. 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second consisting of 50 interlaced fields per second.

Knowing the technical jargon before going shopping should help when making your final decision. Hopefully you are a little clearer and not more confused about HDTV.  We believe after doing your research on the HDTV brands available you will come to the same conclusion we have. The Magnavox HDTV may well have the most crystal clear HD picture when compared to the rest.
