There is no compression, the black bars on a Sony 4:3 XBR use a method called "anamorphic squeeze" so that the content is displayed in it's native aspect ratio and the black bars do not count towards the resolution (wasting resolution data).

While the subject of TV's is being discussed, I have the question for the ages..
I must admit I am totally lost with regard to HDTV.. Gaining in understanding,
but still hopelessly befuddled.


My TV is a Sony WEGA 40XBR800.. This is the 40" tube TV that weighs 305 pounds..
What a monster, but what a picture..


So I decided to take the plunge with Cox and get HD hooked up..
The digital box with Cox is a Scientific Atlanta Explorer 3250HD..

High Definition really is amazing..

So here we go.. Is the picture by definition, necessarily compressed to a
smaller size with black and gray bars as borders in the center of the screen?


I'm having to answer my wife's classic question: "It's really a clear picture
Bill, but why is the picture so small?" Of course she is used to a 4:3 TV where
the picture fills the screen..


HD is compressed, but all my other digital non-HD pictures are compressed also..

Struggling to understand here..

TIA,

Bill
