Windowboxing... Why won't you just fill the whole !#%^ screen?!?

Last night I sat down to watch the premiere of The Chopping Block on NBC and was surprised to see that my broadcast was being windowboxed on the screen.

What is windowboxing you ask? While I am watching this program on my 42" LCD HDTV, there is a thick black outline around the entire image, filling up half of my screen with dead space. This phenomenon is occurring more often recently as we shift into High Definition broadcasting.

The traditional tube television displays in an aspect ratio of 4:3 (for those of you not familiar with aspect ratios, that is the relationship between the length of the image and the height of the image). Brand new High Definition televisions now have a screen that is much wider than it is high, with an aspect ratio of 16:9. Just as the devices we use to watch programming have changed their aspect ratio, the cameras used to record the programs also have changed the shape of the images they capture.

So to get a 4:3 image to display without distortion on a 16:9 screen, the image is pillarboxed: the image is centered horizontally on the screen, and black space fills the left and right sides of the screen. Inversely, to view a 16:9 image on a 4:3 screen, the image is letterboxed: centered vertically, and black space fills the top and bottom.

So what I was seeing on my screen last night, was a program that was recorded in 16:9, but then was converted to be viewed on a 4:3 screen, which was then converted to fit my 16:9 screen. Dizzy yet?

Now this would make sense to me if I was watching a station that does not broadcast in HD, but this was not the case! The program before and after filled my screen with all of their HD glory! Apparently this revolution even confuses the "experts".

I am addicted to the digital world.

Today is a fantastic day. After work, my world will return to normalcy. The void I have lived with for the last 6 months will finally be filled. My new DirecTV service with HD/DVR will be hooked up when I get home!

In my 26 years on this planet, I have never known life before Cable TV. A proud member of “Generation Y,” I was born with a remote control in my hand. I always had cable: growing up, in my college dorm, in my first apartment, and finally in my first house.

This all changed about 6 months ago. Like many other Americans, Nate and I re-evaluated our budget, trying to find ways to save a few bucks here and there. We canceled the land line (only telemarketers call that anyways), combined cell phone services, and even switched to generic soda. Right around this time our contract with Dish Network was expiring, and we thought, “do we really need to spend $85/mo on television when we can just watch the networks for free?” We bit the bullet. We canceled. The Dark Age began.

It wasn’t so bad at first. I re-discovered PBS. My new favorite shows became American Scientific Frontiers and Cook's Country. If nothing was on, I’d actually turn off the TV and move on to other things - take a bike ride, weed the garden, play PS3, rent a Blu-Ray. A new world had opened up.

Then winter set in. A horrible, awful winter. Over 35 inches of snow in December alone! Now, it’s the cold snap that seems to last forever. For the last 2 months, leaving the house has been unbearable! When you are cooped up inside for so long, there are only so many ways you can pass the time. The Locals just don’t cut it anymore. I don’t think I can ever watch another episode of Who Wants to be a Millionaire? or Judge Judy.

But what do I miss most about life before the Dark Age? DVR. I’ve wasted far too much time watching commercials. Now that American Idol is back on, I can’t bear to actually waste 2 hours of my valuable evening time watching it. With a DVR, I can watch an entire episode in 35 minutes, not miss any of the action, and get on with my life.

Oh modern technology, how I have missed you. I promise never to leave you again. I’ll just have to find something else to sacrifice...
