What is HD set top box?
Usual Television set with CRT tube is not capable
of producing picture more than 480 lines with limited depth of colors.
New Generation LCDs can reproduce image quality upto 1080 lines
detailing and beyond. If you have LCD with 1080i or above resolution,
this is known as High Defination television. 1080i gives you 5 times
clearer picture quality. Unfortunately Cable Transmission or Regular DTH
dish tv transmission is not capable of utilizing your LCD capability.
Old standard transmission works with 4:3 aspect ratio which is like
square where as HD offers you 16:9 aspect ratio which is like rectangle
the way LCDs are designed today. Old starndard give mono or stereo
sound output. HD offeres you 5.1 audio output. This goes to two rear
left+right speakers, two front left+right speakers one center and one to
woofer. Giving you realistic natural sound quality. Earlier TVs were
connected with RF cable, current set top boxes offer 3 pin AV cables.
For HD you need to have HDMI port on television. HDMI port is essential
part of HD set top box.
If you do not have LCD with 1080i resolution or
5.1 music system, you wont be able to take advantage of HD channels.
Regular CRT television is not made for HD transmission. Currently there
are only few channels which are offered with HD broadcast. So if you
think you are ready to experiment with this new technology you can go
ahead with this.
