On Monday, the FCC announced the final digital television (DTV) channel assignments in anticipation of the scheduled switch from analog broadcast. Because we haven’t covered this topic yet at TechConsumer.com, it seems like a good time to run through the process for those who may be affected.

Just what is DTV and why the switch?

TV has historically been broadcast via analog radio waves. On February 17, 2009 (scheduled just after the Super Bowl to avoid confusion for last-minute TV buyers), all over-the-air broadcast TV will be transmitted digitally. The digital signal will enable increased picture and sound quality and additional features like HDTV and multicasting, and will at the same time be more efficient than analog transmission, freeing extra spectrum for other uses.

Who will the change affect? The switch from analog to digital will be mandated for over-the-air TV broadcasts only, so those who receive their television signal using an antenna will need to make sure they’re prepared. (Cable and satellite providers will not be subject to the requirement, but much cable and satellite transmission already comes digitally.) To receive digital broadcasts consumers will need a TV with a built-in digital tuner or a converter. The FCC has a page with more details to make sure you’re ready.

On one hand, the switch is great. DTV represents a substantial, noticeable increase in TV technology. On the other hand, the change will require the millions of broadcast viewers to upgrade to the new standard whether they want to or not. At least some of these are likely to find the change an unnecessary expense in time and money. Another problem is that knowledge of the impending switch doesn’t seem very widespread.
