Viewers who watch TV with an antenna, either indoor or atop your roof. If you subscribe to a cable or satellite service, you don't need to take any action.

The television channel rescan is the result of a national channel alignment. Because of demand for faster and higher capacity mobile broadband services, the Federal Communications Commission expanded wireless services through a nationwide spectrum auction. WCMU participated in this auction. The freed up bandwidth for cellular companies required an alignment for the new channel configuration. As part of this national channel alignment, if you watch free over-the-air TV using an antenna, you'll need to need to rescan your televisions to continue receiving your favorite channels.

Friday, October 18, at 3 AM. In order to continue receiving our stations, you will need to rescan after that time.
Nationwide, about 1,000 stations are affected by this change, including WCMU-TV and its three over-the-air channels WCMU-TV PBS, the WCMU Create Channel and the WCMU 24/7 PBS KIDS Channel.
About a decade ago, television broadcasting converted from an analog to a digital transmission system. This digital transition created additional capacity using the same amount of spectrum, so local television broadcasters could now multicast additional channels. That's why WCMU Public Television's over-the-air viewers have enjoyed two new digital channels in addition to our flagship WCMU-TV PBS channel: the WCMU Create Channel and the WCMU 24/7 PBS KIDS Channel.

Beyond providing you with more channels, another benefit of the digital transition is that unused space between the channels is able to be compressed, so more broadcasting fits into fewer frequencies. This and other unused spectrum are being used by wireless carriers and for other mobile broadband uses.

With the popularity of watching video on our phones surging in recent years, demand for mobile broadband has gone up exponentially, so Congress and the FCC decided to rearrange some of the television spectrum to free up airwaves. The FCC is more efficiently allocating this spectrum for new wireless mobile broadband uses, such as the new 5G technologies that are coming.
If you watch television over cable or satellite you donít have to rescan; your provider will have completed the process. However, if you do receive television over-the-air with an antenna, you will need to rescan your television channels. If you haven't rescanned when the frequencies change, then your favorite channels will seem to have disappeared. You need to retrain your TV by rescanning itóand that's a simple process. In fact, when you first set up your digital TV (or analog TV converter box), it had to be scanned to get your stations. This is the same process.

Just take your remote control and press the menu or setup button. Look for an option that says "antenna" or "channel," press it and it will display "auto tune" or "auto scan." Press that and your TV will search and find all available channels. This process should take about five minutes.

It's a good idea to scan your TV occasionally, as new channels may be available since your last scan. So, if you haven't rescanned your TV in a while, you may be pleasantly surprised at the channels now available to you. If you suddenly don't see a channel where it should be, the first thing you should do is to rescan your TV.

There's even a handy interactive digital TV map there which allows you to put in your home address to pull up all the stations that should be available to you with an antenna. Additionally, the National Association of Broadcasters has created an informative website at tvanswers.org.
