Digital Television Information
WHIO-TV began transmitting its digital signal on channel 41-1 in October 2001. Digital television allows for a significantly improved viewing experience called High Definition television or HDTV, which includes higher resolution picture, CD quality sound and the expanded 16:9 aspect ratio screen image. WHIO-TV transmits a digital signal from our transmitter daily, but you can only receive the digital signal over the air with special receivers that are sold by area electronics retailers. If you would like to receive the signal through your cable operator please write or call your local cable provider to request that they carry our signal.
What is digital television?
The picture you currently receive is based on a 55-year-old analog transmission system. In December 1996, the FCC approved the U.S. standard for a new era of television - digital television. In a digital system, images and sounds are captured using the same digital code found in computers. The change to digital will not only significantly improve the quality of the television picture, but also make possible the over-the-air delivery of several simultaneous services to viewers. Digital television makes possible high definition television, multicasting and data transmission.
