What is multicasting?
Multicasting is one of the benefits of digital television. The DTV transmission allows stations to split its signal into 2 or more channels. This allows broadcasters to carry more than one program at the same time. These additional programs would exist on sub-channels.
For example, your favorite station is channel 61. This exists on a digital tuner at 61.1, but it may have another program on 61.2, or 61.3, etc.
Over time, more and more multicast channels may be added. Please check this site for updates.
