Digital TV - Maybe Not Next Month?

I've been writing about the transition from analog to digital television, referred to as DTV, for the last year and a half or so. Here's a refresher.....

Way back in 2005 Congress decided to move to all digital over-air broadcasting to free up spectrum for public safety and make some money by auctioning off the space. Auctions for the spectrum held last year brought in $19.6 billion to the federal government. Congress allocated a little less than $2 billion to provide $40 coupons for digital to analog converter boxes and get the word out to consumers about the change - if you have an analog television and watch over the air your television will not work after February 17 without a converter box.

So far so good - better public safety, some money for the federal government, higher quality digital television and a coupon program for the converter boxes, all with good up front planning.......

Fast forward to last week - on Monday the organization handling the conversion, the National Telecommunications and Information Administration said the program had no money left and a waiting list of 1.1 million converter box coupon requests. They also said approximately 13 million of the 41 million coupons mailed out to consumers had expired after 90 days.

Want more? Here's a quote from a piece in the Los Angeles Times:

In a letter Thursday to key members of Congress, John Podesta, co-chairman of Obama's presidential transition team, said the Feb. 17 conversion should be delayed, though he did not specify for how long. But with the incoming administration facing economic and foreign policy crises, it does not want to add a major problem with TV viewing in its first weeks in office.

Podesta cited troubles with the converter box coupon program as well as inadequate efforts to educate the public about the switch, and the need to help elderly, poor and rural Americans prepare for it.

"With coupons unavailable, support and education insufficient and the most vulnerable Americans exposed, I urge you to consider a change to the legislatively mandated analog cutoff date," Podesta wrote.

Podesta said the waiting list for coupons could climb to more than 5 million by early February.

Also..... Obama's economic stimulus package is rumored to include some money for the analog to digital transition.....

Will the February 17 deadline end up being extended? Right now it sure looks like it.

Digital TV: Goodbye Analog Snow, Hello Digital Losses

We don't have long to go until over-the-air analog television bites the dust, replaced with digital signaling on February 18. Watching televison the "old-fashioned" way (without cable) brings back fond memories of the aerial antenna on top of my parents house. I remember my Dad climbing up on the roof to move the antenna so we could watch Boston Bruins hockey games more clearly. It only took a few trips to the roof before we had one of those fancy motorized antennas with a controller on top of the set - no more roof climbing to redirect an antenna with one of those - just a twist of a dial......

Most of us have come a long way since those antenna days but there are still many in this country who watch television over-the-air. Realizing this, Congress did get out in front of the digital conversion a year and a half or so ago and starting offering $40 coupons (see www.dtv2009.gov ) consumers can use towards the purchase of a digital set top conversion box. Basically these boxes take the digital signal from the air and convert it to an analog signal that an analog TV can use.

Moving to digital has a lot of advantages including a 3:1 channel ratio - you'll have three digital channels for the equivalent of one single analog channel. It also frees up spectrum for new wireless communications services.

There are also some disadvantages though - most analog sets have 4:3 ratio screens while most digital programming is broadcast in wide screen format. This means analog set owners are going to see letterboxing - black bands at the top and bottom of screens. I think the biggest complaint though will be from those who live in areas where broadcast signals are weak.

Let's take a close look. Back when we were watching those Bruins hockey games we expected a snowy picture - if you're not sure what a snowy picture is - here's an 18 second analog transmission video I just shot:



A fuzzy/snowy picture with good audio - it's watchable and it is also listenable. Analog signals fade gracefully (as someone much smarter that me once said whose name I cannot remember). As signals get weaker the picture snows up but is still watchable. The audio is commonly good with weak audio signals - in fact you typically lose the picture before you lose the audio.

Digital transmissions are another story. Weaker signals will cause the picture to randomly lose pixels along with random pieces of audio. Here's a 20 second digital transmission video I just shot showing pixel and audio loss.



Pixel lose is scattered and occurs throughout the video and, if you missed it, audio is momentarily lost at around 5 seconds. Annoying and just about impossible for me to watch for more than a few minutes..... I'm changing the channel!

Over the air digital television is being pitched by many as a go-no-go service, with people saying you will either get the channel or you won't. From what I've seen this is not the case - there is an in between that is not very pleasant - those digital signals do not fade gracefully!
