Why is the switch to digital television happening?
Digital TV provides a more efficient use of our public airwaves. More than one digital channel can be broadcast using the same space needed for just one analog channel. This allows stations like OPB to provide more programs for the benefit of the community. It also frees up extra bandwidth for public agencies, emergency first responders and new data and communication services. Digital TV offers improved pictures, sound and reception. Digital signals are less prone to interference, and pictures are free of snow and “ghost” images. Once you switch to DTV, you can start watching all OPB digital channels right away. And they’re all free when you watch over the air with an antenna or rabbit ears.
