DTV Conversion

WNMU-TV completed our conversion to all digital broadcasting on Saturday, June 6, 2009. Our switch to digital enabled us to broadcast 3 digital channels 24 hours per day.

DTV Troubleshooting Guide

If you’re having problems receiving digital Channel 13 via antenna, we are always happy to help out. You can call us at 800-227-9668, or email dtv13@nmu.edu.

Before calling, here are a few things that you should check:

  • make sure you have a TV set with a digital (ATSC) tuner, or a set-top digital converter box (some older digital sets came without tuners);
  • make sure your antenna is capable of receiving both VHF and UHF signals. Channel 13 is on VHF, just like it always was;
  • if your antenna is old it may work just fine, but you might want to check the wiring and connections and make sure they are secure;
  • if you have a converter box, make sure your antenna is plugged into your converter box, rather than the TV;
  • if you have a VCR or DVD player/recorder with an analog tuner, make sure your converter box is attached to that device;
  • make sure you are using the correct remote control -- after installing a converter box, you will need to use the remote control that came with the box to change channels;
  • make sure you have re-scanned the channels on your TV or converter box – sometimes this is referred to as “adding new channels;”
  • while scanning for channels, you should see a screen where you can see a gauge of signal strength. If you can find any kind of a signal on channel 13, then you know that your antenna is picking up our signal, but it may be too weak to be tuned in. Most digital tuners need about 30-60% strength for a viewable picture;
  • if you have determined that you’re receiving a weak signal, then you’ll need to think about upgrading your antenna, raising the height or adding a signal amplifier;
  • you may also want to check with your neighbors to find out what kind of results they are getting.

Digital TV F.A.Q.

What is digital television?
Digital Television is a new digital broadcast standard where images and sound are captured using the same digital code found in computers. Dramatically improving the picture and sound quality in comparison to the current analog television technology, DTV provides broadcasters the ability to send more varied information over the airwaves, cable and satellite. DTV replaced analog television in the U.S. in June 2009.

What is high definition television (HDTV)?
Digital television allows stations to broadcast programs in much higher resolution or clarity than standard analog television. This is called high definition television or HDTV. Viewers at home can receive high-quality, crystal-clear pictures. These visually stunning pictures, with more than twice the resolution and clarity of standard television, are displayed in a wide-screen format with a 16 by 9 width-to-height ratio compared to the old 4 by 3 format. And because HDTV is digital, audiences have the benefit of six-channel CD-quality "surround sound." In other words, DTV viewers can enjoy a true home theater experience.

Can I watch digital television on my existing set?
Not without a set-top convertor box. Because DTV information is encoded in a different way than the analog signal, it requires a different kind of receiver; thus, digital programs can only be seen on a digital television set or by "down-converting" to your current analog set with a set-top converter box or digital cable box. Down-converting will not give you the full benefit of HD programming, but the video will still look better than analog broadcasts.
